surface only frosted ^A'ith white must be very difEerent to the " tail 

 white throughout " of L. hypsibius. 



There is no other Hare in any way nearly related to this Sechuen 

 form, L. oiostolus {=L. palliiies) 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.

This little Pika is very much like 0. roylii from Sikhim, but is 

 a smaller animal. 



I now add Mr. Styau's notes on seven species of Chinese 

 Squirrels : — 



1. SciUEUS VULGARIS L. (probably subsp. calotus Gray.) 

 Pekin. Greyish black above. 



2. SCIUEUS DAVIDIANUS M.-Edw. 

 Pekin, N.W. Sechuen, Shensi, Hupeh. 



A mountain species, probably mostly found at high altitudes. 

 8. davidianus consobrinus Berezowski does not seem really separable. 



3. SCIUBUS PERNYI M.-Edw. 



"West Hupeh, North Kweichow, Anhwei, N.W. Eokien, Yunnan. 

 A mountain species probably not descending below 3000 ft. 

 S.JJavipeetus David, Journ. 3"^" Voy., refers to this Squirrel, 



4. SCIITEUS PYRRHOMEEUS Thos. 



Ichang and Sinyang (Kweichow). 



Also a mountain species; only found hitherto in the aboA^e men- 

 tioned two localities. 



5. ScitJEUS CASTANEovENTEis Gray. 

 Chekiang, Eokien, &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.
