36. Arctomys tibetanus, Hodgs. J.A.S. xii. 409. 



In presenting this animal to the Museum, Mr. Hodgson gave 

 us personally the following remark respecting the two species of 

 this genus described by him, and their respective specific names 

 and localities: — "The Bobac, Arctomys himalay anus, Hodgs., 

 A. Bobac, Schreb., is found only in the higher regions of Tibet, 

 while the A. tibetanus, Hodgs., inhabits exclusively the lower 

 regions of Himalaya; but inadvertently the respective locality 

 of the two species has been alternated in my descriptions." 



Among the Squirrels sent by Mr. Hodgson there are several 

 specimens of the Sciurus M' Clellandii, Horsfield, Proc. Zool. 

 Soc. 1839, p. 152, which was discovered by J. McClelland, Esq., 

 in his visitation to Assam as a member of the deputation on the 

 Tea-plant, and described in the Report of his contributions of 

 Mammalia and Birds to the Company's Museum. It is thus 

 described : —

 sime irroratus notseo saturatiore; subtus ex sordido fulvo-

 oculos extensa, postice obsoleta in uropygio utrinsecus ap-

 cent shade, rather deeper on the back, minutely grizzled with

 yellow : on the middle of the back from the neck to the rump 

 is a deep black stripe, and somewhat lower a brownish -black 

 stripe of the same extent, adjoining which, on each side, is a

 towards its termination. . Ears large, black exteriorly, delicately
