    The characters of spinal nervous plexuses were investigated in six Snub -nosed monkeys, including Rhinopithecus bieti (3 ♀♀), R. roxellanae (1 )and R.brelichi (2 ♂♂) . Through comparison with other primates on the cervical plexus, the brachial plexus and the Iumbosacral plexus; the followings arc considered to be significant.

    This paper deals the skull and the teeth of the golden monkey (Rhinopithecus rxellanae Milae-Edwards ) . It can be obviously observed that there are many remarkable differences in skull characters between the golden monkey and the rhesus macaque (Macaca mulatta) and the banded leaf monkey (Presbytis francoisi), i.e.the golden monkey's skull is higher in form, the occipital arises externally and upwardly from the foramen magnum; the cranial length-auricular hight index, the cranial capacity, the total prognathism and the anterior inclined corner of mandible all are larger in golden monkey. The tubers and trochanters of the skull, the remarkable trochanters of the stronger mandible give the larger attaching surface for the musculus temporalis and the musculus masseter, and we believe that these structural characters of the golden monkey are related with chewing and tearing of the stronger and tougher phloem, nuts and drups. The stronger crista superciliaris can shade the eye to prevent the rain and snow in the wild. The authors also considered that the bluntness of the teeth may be related to its food habit, chewing of coarse materials.

    The colony structure of the golden monkey, Rhinopithecus roxellanac Milne-Edwards, is composed of many"families" or "microcolonies". Every "microcolony"contains one stronger male,three to five females,some young under three years old and infants. This structure, using"microcolony" as the center of association may be related directly or indirectly to sexual behavior. There are fightings between adult males for hegemony of females and establishing a sequence of dominancy, Whenever the sequence has established, the"recognition"and the"tacit understanding"of the "principle of having property"are efficacious,then the males abide the sequence each other, and refrain from unnecessary fightings.Every natural colony has a fixed homerange, when two neighbourings meet in looking for food, they will go away quickly to different directions.The young males become adult about at seven years old,and the young females at four or five years old. The copulation season is in August, September, and October. the period of pregnancy is about six months,and the labor season is centralized in March, April and May. A learning experiment was carried out by teaching the youngs to take the sweet from different containers. that showed a higher ability of learning.

    The breeding phenomena of rhesus monkeys (Macaca rnulatta ) were investigated in the monkey breeding ranch of Kunming Institute of Zoology from 1961 to 1966. The investigations were especially emphasized on the following problems such as: The group reproductive rate, the favorite period for reproduction and some breeding problems under domestication.The frequency of pregnancy might approach 90% and the average was 69.8%, The normal frequency of parturition might be 100% and averagely 82.2%. The favorite period for reproduction was from Feb. to June every year, and the high peak for parturition was within the period from March to May.If we want to breed monkeys in cage conditions we must put special emphasize on: the careful selection of breeding stock, the chosen of suitable method of breeding and both the breeding adults and the newly born young monkeys must be carefully treated in management.

    Many fossils of Mi-deer Elaphurus davidianus were discovered in 95 sites in the Eastern part of China. A pair of relatively intact fossil antlers has been described in detail in this paper (pl.I). Fossil and living antlers from more than 50 individuals have been studied and compared (pl.ll, Tab. 2 ) . Methods and terms for description of the antlers have been suggested (Fig. 1, Tab. 1 )According to the information collected (Tab. 3 ), it is believed that an evolutionary sequence is ranging from Elaphurus lantianensis through E. chinanensis and E. bifurcatus,to E. davidianus. Of course,the evolutionary stage does not mean that one species was originated from the other directly.

    This paper gives a systematic review of the ferret badger (Melogalc moschata ) recorded from China. In this species, 6 subspecies are recognized, in which 5 occur in China. The specimens discovered in Guanxi belong to M. m. taxilla, and is new record of subspecies in China. The specimens discovered in western Guangdong and Hainan Island,have been ever considered as M. m. moschala with in 50 years, but it is recognized as a new subspeoies now, and is described as follows:Melogale moschata Ilainanensis, subsp. nov.Holotype- No. 051,, adult, collected on January 26, 1963 from Dali, Hainan Island.Paratypc: No. 0188,, 0479,, adult. collected on January 24,1963 and on December 29, 1964 from Mountain Ba wangling, Mountain Dinoluo of Hainan Island. The type specimen arc deposited in the (Juangdong Institute of Entomology.Diagnosis: The dorsum is brown-tan in colour,the abdomen is apricot yellow. The tail likes a broom. Interorbilal breadth is narrower. Discrip-tion: The colour of the body, deep and bright, dorsum the body, brown-tan; needle-hair without white tip; the forehead has a apricot yellow stain, the colour of the body sides is paler, and is mingled slightly apricot yellow hair tipe. The lower part of the body is apricot yellow from jaw to the base of tail; hair of tail is hard and flully, the tipe of tail likes a broom.Skull strong, interorbital breadth narrow, generally smaller than 20mm; zygomatic arch, wide and hard; temporal ridges, straight forward and thickened.

    From 1973-1980, a total of 3,571 house mice were captured from various habitats and of all seasons in Taxihe, Manas county, Xinjiang Uygur Autonomous Region. Measurements of length and weight of body were taken for studying the relative fatness of the mice.The auther calculated it by means of the following formula which was introduced into small mammal's investigation by Hsia et al (1963) from ichthological study:K= 100W/L3,where K represents the relative fatness, W the weight in gram, L the length of head and body in cm.The results show that the relative fatness of house mice has the following features :There are no obvious differences in sex or in various groups of age (Table1 ) .The difference of relative fatness between various habitats is evident especially in October (Table 2 ) .There are obvious seasonal fluctuations. It is medium in spring (K = 3.19), the lowest in summer (K = 3.11 ), the highest in the middle of october (K = 3.38 ), but before winter coming, it drops evidently and keeps the valus until next spring (K=3.14 ) (Table 3, Fig. 1 ) .

    Plateau pika (Ochotona curzoniae) is one of the important pest rodents in the Qinghai-Xizang plateau. The grassland is destroyed wherever the pika population is in great number.This paper deals with the relations between the vegetation and the density of the pika in grassland according to the observations carried out in the alpine meadow of Men-Yuan, Qinghai, during August, 1980.The relation can be shown in the following binary linear regression equation. y = 101.34 - 0.8894x1 - 0.1811x2. y is the density of plateau pika, while x1 and x2 represent the cover-degree and height of the vegetation respectively.The result indicates that both the cover-degree and height of the vegetation influence the density of the plateau pika directly: the higher the cover degree and height of the vegetation, the lower density of the pika. The plateau pikas are difficult to be found in man-made grassland where the planted grasses are high.For control measure of the pika, it is important to improve the grassland.
