the under surface is white, as are also the feet and inner surface of 

 the legs, the hairs being uniform to the roots. The hairs of the 

 tiiil are for the most part of a light ash colour at the roots ; above 

 the ash colour on each hair there is a broad but not well-defined 

 ring of light rufous ; this is followed by dark brown, and at the tips 

 the hairs are rufous and gray. Many of the hairs of the tail, how- 

 ever, are \vhite, some of them are black, and othcrs almost uniform 

 rūsty yellow.

" On the back and tail there are so many \vhite hairs iuter- 

 spersed, the white spot on the head being merely occasioned by 

 a greater number of hairs nearly or wholly white, that there is great 

 reason to believe that this species becomes much lighter, if not 

 ■tt'holly \vhite, during \vinter. 



" In the shape of the head and ears, and in the pointed projec- 

 tions of the teeth, this species approaches the Marmots and Sper- 

 mophiles ; but in the shape of its body, its soft fur, its curved and 

 acute nails, constructed more for climbing than digging in the earth, 

 and in the third toe being longer than the second, it mušt be placed 

 among the Sąuirrels." 



Mr. Waterhouse exhibited a new species of Hare from the coUec- 

 tion made for the Society by the late Mr. Douglas, and pro- 

 posed to characterize it under the name of Lepus Bachmani : he 

 thought it probable that the species had been brought from Cali- 

 fornia. It was thus described : 



Lepus Bachmani. Lep. intens^ fuscus, pilis fuscescenti-flavo ni- 

 groque annulatis ; ahdotnine sordide albo : pedibus supra pallidis, 

 subtus pilis densis sordide fuscis indutis : caudd brevi, albd, suprč. 

 nigricante, flavido adspersd : auribus exteme pilis brevissimis 

 cinerescenti-fuscis, intertie ulbidis, ad marginėm extemnm, et 

 ttd apicem flavescentibus obsitis : nuchd pallidi fuscescenti- 

 flūvd. 



" Fur long and soft, of a deep gray colour at the base ; each hair 

 annulated near the apex viith pale brown, and black at the points ; 

 on the belly the hairs are whitish extemally ; on the chest and fore- 

 part of the ncck the hairs are coloured as thoseof the sides of the body; 

 the vibible portion is pale brovvu, each hair being dusky at the tip ;
