RESULTS FROM TRE MAMMAL SURVEY. 429 



Fur soft and close, without spines. General colour above "hair 

 brown," very dark, almost black along the median dorsal line, more 

 and more tinged with " ochraceous buff " towards the flanks, 

 beloAv pure white, with a collar at the base of the throat, extended 

 backwards along the median line of the abdomen, the same colour 

 as the back, the line of division of the upper and under surfaces, 

 along the sides, sharply marked. Feet white. Tail dark above, 

 pale below, often with a white tip, sparsely clothed with short, 

 adpressed, black hairs, the terminal one-sixth further with longer 

 finer, white hairs. 



Skull slightly longer, and markedly narrower than in fidvescens, 

 tooth row slightly shorter. 



Dimensions of the type : — (Those of the body taken in the flesh 

 by the collector). Head and body, 133 ; tail, 170; hindfoot, 28 

 ear, 22. Skull: — Greatest length, 37.5; condylo-basal length, 34 

 brain case breadth, 14.5 ; interorbital breadth, 6 ; nasals length, 15 

 diastema 9.5 ; palatal foramina, 6 ; tooth row, 5.3. 



Habitat — Sikkim. (Type from Chuntang. Alt. 5,350 feet.) 



Type.— Oldi female. B. M. No. 15. 9. 1. 185. Original number, 

 5968. Collected by Mr. Crump, on the 17th December, 1914. 

 Presented to the National Collection by the Bombay Natural 

 History Society. 



Mr. Crump obtained this species only at Chuntang and Lachen, 

 at between 5,000 and 9,000 feet altitude, where he got a series of 18 

 specimens. The specimens of niviventer obtained by him in 

 Kumaon were found at about the same altitude. No specimens of 

 niviventer w^ere found in Sikkim nor of leiiclia in Kumaon. 



4. — The Local Races of Funambvlus rExxANTi. 



Some years ago I pointed out in this Journal (Vol. XVI., p. 406, 

 1905) that Funamhulus ])almarmn and 2^ennanti were two quite dis- 

 tinct species and at the same time I described a local race of j>6%- 

 nanti, from Rawal Pindi, under the name of argentescens. In the 

 Collections of the Mammal Survey, a large number (more than 

 250 specimens ) of 'pennanti have been received from a dozen 

 different localities and of these only one series turns out to be 

 the northern form arcjentescens, viz., that from Sind, while all 

 the rest have in the Survey Reports been classed as F. pennanti 

 pennanti. On laying out all these specimens it became evident 

 that there is another local form, at and round Palanpur, which 

 is quite distinct from both true pennanti and p. argentescens, I 

 propose to call it 



Funambiilus pennanti lutescens, sub. sp. nov. 



A Funamhulus rather smaller than true pennanti, about the size 

 of argentescens, but much paler than either of these two forms.
