Show 1899.] ON CHINESE MAMMALS. 577 surface only frosted with white must be very different to the white throughout " of L. hypsibius. There is no other Hare in any way nearly related to this Sechuen form, L. oiostolus (==L. pallipes) being a far smaller animal ; and although the skins at my disposal are in too bad condition to make fair comparison, the skulls show very wide differences, and prove that these two Hares belong to quite distinct groups. The grooves of the upper incisors are filled with cement; the infolded enamel, seen on the cutting-edge of the tooth, has its sides almost in contact, so that the cement forms a simple straight line, rather nearer the inner than the outer edge of the tooth. The front face of each tooth is almost evenly sloped off towards the sides, the portion on the inner side of the grooves being only very slightly or barely perceptibly raised. LEPUS SWINHOEI.

This little Pika is very much like 0. roylii from Sikhim, but is a smaller animal. I now add Mr. Styan's notes on seven species of Chinese Squirrels :- 1. SCIURUS YULGARIS L. (probably subsp. calotus Gray.) Pekin. Greyish black above. 2. SCIURUS DAYIDIANUS M.-Edw. Pekin, N.W. Sechuen, Shensi, Hupeh. A mountain species, probably mostly found at high altitudes. S. davidianus consobrinus Berezowski does not seem really separable. 3. SCIURUS PERNYI M.-Edw. West Hupeh, North Kweichow, Anhwei, N.W. Fokien, Yunnan. A mountain species probably not descending below 3000 ft. S.fiavipectus David, Journ. 3me Voy., refers to this Squirrel. 4. SCIURUS PYRRHOMERUS Thos. Ichang and Sinyang (Kweichow). Also a mountain species; only found hitherto in the above mentioned two localities. 5. SCIURUS CASTANEOVENTRIS Gray. Chekiang, Fokien, &c. A mountain species found right down to the foot of the hills, but not extending on to the plains; common in above two maritime provinces. |
