—;222 ZOOLOGICAL GEOGRAPHY. [part in.Mammalia.—This sub-region contains a number of peculiarand very interesting forms, most of which have been recentlydiscovered by Pere David in North and West China and EastThibet. The following are the peculiar genera Rhinopithccus,:a sub-genus of monkeys, here classed under SemnopitheousAnurosorex, Scaptochirus,Uropsilus and Scaptonyx, new forms ofTalpiche or moles ; JEluropus (iEluridte) ; Nyctereutes (Canidae)Lutroncctes (Mustelida?) ; Cricetulus (Muridse) ; Hydropotes, Moschus,and Elaphodus (Cervidse). The Rhinopithecus appears tobe a permanent inhabitant of the highest forests of Moupin,in a cold climate. It has a very thick fur, as has also a newspecies of Macacus found in the same district.East Thibet seem to be very rich in Insectivora.North China andScaptochirus islike a mole ; Uropsilus between the Japanese Urotrichus andSorex ; Scaptonyx between Urotrichus and Talpa. JEluropusseems to be themost remarkable mammal discovered by PereDavid. It is allied to the singular panda {JElurus fulgens) ofNepal, but is as large as a bear, the body wholly white, withthe feet, ears, and tip of the tail black. It inhabits the highestforests, and is therefore a true Palsearctic animal, as most likelyis the JElurus. Nyctereutes, a curious racoon-like dog, rangesfrom Canton to North China, the Amoor and Japan,and thereforeseems to come best in this sub-region ; Hydropotes andLophotragus are small hornless deer confined to North China ;Elaphodus, from East Thibet, isanother peculiar form of deer;while the musk deer (MoscJms) is confined to this sub-region andthe last. Besides the above, the following Palaearctic generawere found by Pere David in this sub-region : Macacus ; fivegenera or sub-genera of bats (Vespertilio, Vcsperus, Vesperugo,Rhinolophus, and Murina) ; Erinaceus, Nectogale, Talpa, Crociduraand Sorcx, among Insectivora; Mustela, Putorius, Martes,Lutra, Viverra, Mcles, JElurus, Ursus, Fclis, and Canis, amongCarnivora ; Hystrix, Arctomys, Myospalax, Spcrmophilus, Gerbillus,Dipus, Lagomys, Lepus, Sciurus, Ptcromys, Arvicola, andMus, among Eodentia; Budorcas, Ncmorhcdus, Antilope, Ovis,Moschus, Cervulus and Cervus among Kuminants ;and the widespreadSus or wild boar.The following Oriental genera are also
