    Sivapithecus lufcngensis shows a great magnitude of sexual dimorphism, as justified previously on the basis of abundant materials. The sexual dimorphism of Laccopithecus robustus in Lufeng is also markedly expressed. Reexamination of the specimens reveals the facts that: 1) diastemata between maxillary second incisors and canines are evidently present on both sides in one specimen (PA 876) , while absent in another (PA 860) ; 2) lower canines show a striking difference in size which could not be considered to represent different individuals of the same sex. Because of the small sample size we do not adhere to the average magnitude of the sexual dimorphism we have determined. Nevertheless, this marked expression of sex difference is definitely not merely an accident of small sample size. The reduction of sexual dimorphism is revealed in an additional primate lineage-gibbon lineage.
    Comparative studies indicate that Sivapithecus lufengensis is sexually more dimorphic in dental measurements than those of chimpanzees, gorillas and orangutans. The average and the coefficient of variation of the reductions of the dimorphism indices from Sivapithecus lufengensis to each kind of extant great apes are used to describe the extent and the nature of dimorphism change. Chimpanzees have the largest average and the smallest coefficient of variation in extant great apes. That seems to say, in chimpanzees, the reduction of sexual dimorphism from the condition of Sivapithecus lufengensis is most marked and, more importantly, most proportional in dental measurements. This fact strengthens the claim on the close phylogenetic relationship between Sivapithecus lufengensis and extant chimpanzees.

    Gigantopithecus teeth, 610 in total, from the cave at Liucheng were examined for evidence of hypoplasia. The teeth were observed under a low-power binocular microscope. The hypoplasia can be found on most types of posterior teeth, including the third molars. A high incidence (14. 3—17. 9%) is shown by a calculation on individual basis. The results suggest that the Gigantopithecus is as susceptible to enamel hypoplasia as australopithecines of South Africa.
    Though there are many etiological factors responsible for hypoplasia, malnutrition seems to be a major one in the case of Gigantopithecus. This assumption follows from two facts: a high incidence of dental caries in Gigantopithecus (Woo, 1962) , and the coexistance of Gigantopithecus with Homo erecus (Zhang, 1985) . The facts imply a limitation in food types and a shortage in food sources, and a result in nutrition, malnutrition, could be expected in Gigan*opithecus.

    The author has calculated the coefficients of divergence among skulls from upper Paleo-lithic China and Niah cave. The results are as follows.
    Niah-Liujiang 0. 033
    Niah-Upper Cave 101 0. 078
    Niah-Upper Cave 102 0. 050
    Niah-Upper Cave 103 0. 048
    Upper Cave 102-Upper Cave 103 0. 030
    Liujiang-Upper Cave 101 0. 056
    Based on these figures and referred to the figures provided by D. Brothwell in his paper on Niah Cave Man (1960, Niah-Talgai 0. 057; Niah-keilor 0. 061) , we can find that Niah and Liujiang are very close. If the figure between UCI02 and UCI03 can be considered as representing the normal intrapopulation divergence for the same sex, the degree of difference between Niah and Liujiang is probably even as close as that of intrapopulation one. The affinity between Liujiang and Upper Cave is less than that between the former and Niah.
    There are morphological features worthy of mentioning. The cranial index of Niah skull (77. 8) is very different from those in Australian and Indonesian late Pleistocene skulls (Talgai 73. 4, Keilor 72. 6, wad jak I 74. 5) . On the contrary it is closer to those of Liujiang skull (75. 1) and Ziyang (77. 8) . The shape of the upper dental arch of Niah is similar to that of Liujiang and different from that in Australia. The palatal index of Niah (78. 9) is much higher than that of Talgai (64. 5) . Although it is close to that of Keilor (83. 5) but the absolute length of palate of Niah (47. 5 mm) and Keilor (56. 5 mm) are very different. So does the breadth of palate (37. 5 mm for Niah, 47. 2 mm for Keilor) , while the Niah palate is similar to that of Liujiang in absolute measurements and index (45 mm in length, 36 mm in breadth, 80. 0 in imdex) .
    Indeed, the coefficient of divergence between Niah and Tasmanians is slightly lower than that between Niah and Liujiang.
    The author considers that the results gained from comparing upper paleolithic Niah man with upper paleolithic man in both China and Australia are more valuable and reasonable than that gained from comparing Niah man with modern man. The affinity between Niah and Liujiang is closer than that between Niah and Australian Pleistocene ones. Niah man was probably the product of gene exchange between the Asian and Australian continents. Another possibility is that Kalimantan might have acted as a transfer station on the way of human migration from Asian continent to Australia. Considering the early date of Niah man the latter possibility seems more probable.
    The agenesis of lower third molar is more frequent in Mongoloids (Eskimo 36. 6%, modern Chinese 5. 14%—40. 6% according to different authors) than in Australoids (1. 5%) and can be traced as early as Lantian mandible dated more than half million years ago.
    There is a longitudinal thin ridge along the median part of the nasal bone from Tabon. Similar structure can be seen in Homo sapiens fossils in China (Dali, Maba and Upper Cave101).
    The above mentioned two phenomena in the Tabon specimens may probably imply the influence from Asian continent than that from the South. Tabon man might be a represent ative of the product of interbreeding between early man of Australian and Asian continents.

    The thickness of the cranial vault at the midline on the mid-frontal squama, pre-bregmatic eminence, frontal at bregma, parietal at vertex, occipital at lambda and the external occipital protuberance was recorded in 40 male and 7 female Northern Chinese crania, 47 male and 52 female Australian Aboriginal crania and 13 male European crania using specially nodified vernier calipers. Comparison of vault thickness data obtained through direct measurement with those obtained from lateral radiographs indicated that direct measurenent provided consistently more accurate results.
    Male and female samples were processed separately so that the extent of sexbased variation could be examined. Student's t test was used to compare the sample means and the percentage of sexual dimorphism for each dimension was calculated according to Garn et al. (1964) . The possibility of an allometric association between the thickness of the bones within the cranial vault, size of the cranial vault and stature was examined using Spearman's rank correlation coefficient and the Australian Aboriginal sample.
    All but one of the mean thickness dirmensions in the Australian Aboriginal male sample is significantly greater than the Northern Chinese and European means. The female results support those obtained with the males. In both males and females thickness at the external occipital protuberance, in all of the populations examined, did not correlate highly with that obtained from other parts of the cranial vault. This reflects the high degree of morphological variation in the position of the internal occipital protuberance and its influence on cranial vault thickness dimensions recorded at the external occipital protuberance. The European and Northern Chinese samples have similar cranial vault thickness dimensions. The Spearman's rank correlation coefficient matrix scores provide some support for a biological association between vault thickness and overall cranial size. However, there appears to be little support for an association between stature and cranial vault thickness. The difference between the male and female mean vault thickness dimensions were significant at bregma, vertex and the external occipital protuberance in Australian Aboriginals and lambda and the external occipital protuberance in Northern Chinese. Some caution is needed in the interpretation of the Northern Chinese female data as the sample is extremely small.
    Evidence of trauma, supressed fractures, is extremely common on the vaults of Australian Aboriginal crania from southern and central Australia. Traditionally Australian Aboriginals, males and females, involved in agressive dispute will use a substantial wooden implement and strike to the head of thir opponent (Meggitt 1962) . The injuries that result from this are more common in females than in male. This form of social interaction must have rigorously selected against those individuals with thinner bones in their cranial vaults. To a large degree this may explain the greatly thickened vaults in Australian Aboriginals relative to Europeans and Northern Chines. This may also provide a clue to the factors resulting in the development of marked cranial vault thickness in Homo erecius.

    Based on the temporal and morphological sequence of early man in China and their geographical position, this paper suggests that early man spread from south to north in China. They were restricted to south of Yangtze River in the Early Pleistocene, then dispersed to the north of Qinling Mountain and south of Yellow River in the early Middle Pleistocene. Later, Peking Man spread further to the north of Yellow River and arrived at N 40°, the northern limit of Homo erecus so far known in China.

    This paper is based on the investigation of 2281 girl students of Han and some women peasants of Han in the country in Xian City and Kaiyuan County of Liaoning Province. The mean menarcheal age is 13. 50 ±1. 21 years in Xian and 14. 40±1. 40 years in Kaiyuan. The me- narcheal age tends to be earlier than expected. It is more obvious in the country. The method of life table is better than other statistics methods. The status quo method is more accurate in the investigation. The results were compared with the reports at home and abroad. The frequency of occurrence of menarche in different seasons and the factors influencing menarche were analysed.

    A preliminary research on the physical charateristics of Yugu nationality was made in 1984. The 8 observational items and 51 measurements of adult 210 males and 199 females of Yugu nationality in Gansu province were investigated. The conclusions are as follows:
    The mean stature of males is 1672. 72 mm, and that of females is 1562. 76 mm. The span of arm is larger than the stature in both sexes.
    The cephalic index is of mesocephaly and brachycephaly in both sexes. The facial form is leptoprosopy and hyperleptorosopy in both sexes. The nasal root height is larger than that of other nationalities.
    In addition, 79. 6% of both sexes have eyefold on the upper eyelid. The proportion of Mongolian fold among males is 39. 8% and among females is 40. 2%. The nationality has not only some common characteristics of East Asian type of Mongoloid but also its own special ones.
    In comparison of some measurements with other nationalities in China, Yugu nationality is closer to Han nationality in North China, Dawuer, Qiang and Sibo nationality, and further from Li and Miao nationality.

    The late geologist Yu Shiyuan collected some paleolithic artifacts in the Liangshan area in July 1951. These remains constituted the first discovery of the earliest evidence of human activity in the Hanshui R. valley. Unfortunately, it had been neglected for a period preceding 1980. In 1980, under the effort of Prof. Yian Jiaqi of Xian Mining College, the site once more saw the light of day.
    The total number of Yian's collection is 1000 artifacts or more, but most of them were from surface collections. In 1982, the first author of the present paper went to Liangshan and found more than 30 stone artifacts from the surplus gravels in the quarry of the Lunggang Temple brickkiln. In addition, two pieces were obtained from exeavation. In the spring of 1985, 108 stone artifacts were also collected by the Archaeological Institute of Shaanxi province. In November of the same year, a team from the IVPP and Banpo Museum went to Liagshan and continued the investigations. 147 additional paleoliths were found. Among them, 81 came from the quarry of the Lunggang Temple brickkiln. It is especially fortunate that Tang Yingjun and Zong Guanfu of the IVPP and some colleagues of Geological Museum of Shaanxi province have found several Paleolithic lo?alities and associated mammalian faunas in the other areas of the Hanshui R. valley, Therefore the study of Liangshan paleolith has entered a new stage.
    The Liangshan site is situated in the quarry of the Lunggang Temple brickkiln, about 10km southwest of Hanzhong city, Shaanxi province (106°58E, 33° 3'N) . This is the upper reaches of the Hanshui R. and southern margin of the Hanzhong Basin, attached to the Dabashan Mt. in south and overlooking the Qinling Mts. from the other side of the Hanshui R. in north. The height above sea level in the basin is 510-530 m. (Fig. 1).
    Five terrace levels of Hanshui R. can be seen in Lunggang Temple area and measure 6— 10 m. , 15-20 m. , 40-50 m. , 60—80 m. and 150-170 m. above the present level of Hanshui R. respectively. The section yielding stone artifacts is located in the upper deposits of the third terrace mentioned above. Exposed thickness is 8-10 m. The sequence of the section from top to bottom in turn is as follows (Fig. 2):
    6. Brownish red, brownish grey clay, thickness 0. 2-0. 5 m.
    5. Greyish drab fine sand, thickness 0. 2 m.
    4. Blackish drab clay, thickness 0. 2-0. 3m.
    3. Reddish drab sandy clay, thickness 2-8 m.
    2. Gravel. Scattering 1-2 m. above ground. The stone artifacts were found in this layer.
    1. Greyish brown, greyish green crystallian complex which consists of the bottom of the third terrace, local exposed thickness is 2-3 m.
    More than 1, 000 stone artifacts have been collected by the scientists from Liangshan area since 1980. Among them more than 200 pieces were obtained from the layer 2 of the third terrace level in the quarry of the Lunggang Temple brickkiln in situ, while the rest were collected on the surface of the fourth and fifth terrace levels and the top of hills nearby. The raw materials employed for making artifacts consist of cobbles of quartz, volcanic rock and quartzite from the gravel of the third terrace.
    Direct free-hand blows and the "bipolar"methods were used to flaking, but the former is in the majority. The retouches of tool were made by stonehammer. The tool types include chopper, choppingtool, spheroid, biface, cleaver, pick and scraper. Of them, the chopper, chopping-tool and spheroid are the most common. The size of these types is generally big, belonging to the heavy-duty tools. There are some light-duty tools, too. However, they cover only some scrapers, a few of spheroids and chopping-tools. Most of the tools mentioned above were'made of cobbles.
    In typology, technology and size, Liangshan Stone Industry is similar to those of Lantian, Kehe, Sanmenxia city and Dingcun located in the "Fen-Wei Graben" at north slope of Qinling Mts. and especially the Sanmenxia city. All types of stone implement found in Sanmenxia city can be seen in the Liangshan site. Liangshan Stone Industry also can be compared with that found in the Baise Basin of Guangxi Zhuang Autonomous Region in South China. The only difference is that the spheroids have not been found and the bifaces hold the third place in number succeeding choppers and chopping-tools in Baise.
    In early Paleolithic industries of East Asia, the Chongoknian in Korea peninsula is comparable to the Liangshan Industry. The former is known as a "Biface Culture" which can be compared with the Achelean Culture of Europe and Africa. Liangshan Industry also resembles very much those of the Oldowan and Developed Oldowan from the Oldovai Gorge in East Africa. There are no essential differences between the heavy-duty tools of Liangshan and Oldovai except that the light-duty tools of Liangshan are much less.
    In 1940s, Hallam L. Movius proposed his "two culture theory", the "chopper/chopping-tool culture" of East and the "hand-axe culture"of West. However, this synthesis is not in accord with objective reality of the Paleolithic World. As the first author of the present paper mentioned in another paper, biface is not "absentor "rare" in East and South Asia. There are some stone industries yielding biface, and Liangshan Industry is a good example.

    A lower jaw bone of deer, very thick, was found from the Salawusu Formation of the Late Pleistocene in Inner Mongolia not long ago (Wei Qi, 1983, p. 93) . Its swelled condition below the middle lobe of Msis similar to that of Megaloceros pachyosteus of Zhoukoudian Locality 1 (Table 1) . It seems that this jaw can be referred to Megaloceros pachyosteus rather than Megaloceros ordosianus. It is possible that Megaloceros pachyosteus survives after the end of the Middle Pleistocene in North China.

    Seventeen fossil bones and teeth of mammals from the deposits of Hexian and Chaoxian, Anhui Province, where human skull, teeth and occipital bone were found, were dated with uranium series dating method. The closed system of these samples was tested. This paper gives the age ranges of 150-190 ka and 160-200 ka for Hexian and Chaoxian fossil human sites respectively. But it can not be excluded that samples (especially, the samples from Chaoxiany with an older age (less than 270 ka) might exist in the lower parts of these deposits.
