On the Anatomy of Snub-Nosed Monkeys.notes on the dermatoglyphics of both Rhinopithecus roxellanae and R.bieti

Rhinopithecus roxellanae (Snub-nosed monkey),is a kind of Old World monkey,belonging to Order primates,Family Cercopithecidae,Subfamily Colobinae.It is stated that this genus includes four species,viz.R.roxellanae,B.bieti,R.brelichi and R.avurculus,distribution in China and North Vietnam.Besides R.avurculus inhabiting North Vietnam,all of them had being considered special kinds in China.It is said that the specimens obtained in South-East Yunnan seems to be of R.avurculus.But somebody,for example Elloit (1913),Ellerman (1961) and Mohnot (1978),take this genus as two specieses and two subspecieses,viz.R.roxellanae roxellanae,R.r.bieti,R.r.brelichi and R.avurculus.We suggest it may well be that own views will be produced for the morphological difference among them and classificatory place based on the articles of dissecting data.
