SUMMAKY 0\^ THE RESULTS FROM THE INDIAN 



MAMMAL SURVEY 



OF THE 



BOMBAY NATURAL HISTORY SOCIETY. 



By R. C. Wroughton, f.z.s. 



Part IV. 



(^Continued from page 379 of Volume XXVI.) 



Subfamily II. — Marmotin^. 

 Gen. — Marmota. 



There is only one genus. The name Arctomys, used by Blan- 

 ford, was proposed by Schreber in 1780, but Blumenbach had 

 already given to the genus the name Marmota in 1779. 



The material available in this 



group is very scanty, especiallj^ of 



No. 259. himalayanus, the more eastern forms. Even 



Hodgs. with the help of Hodgson's types 



No. 260. hodgsoni, Blanf. and drawings I cannot convince 



No. 261. caudatus, Jacq. myself that there is any specific 



difference between his himalayanus 

 and hemachalanus (i.e., hodgsoni, 

 Blanf.), and propose to treat the latter name as a synonym of the 

 former, at any rate until, if ever, there is material to prove to the 

 contrary. Good series of marmots, from both slopes of the eastern 

 Himalaya, are a great desideratum. Thomas has recently exa- 

 mined the more western forms, belonging to the caudatus group 

 (J. B. N. H. S, xxiv, p. 341, 1916), when he added stirlingi to the 

 existing species. The species described by him in 1909 (A. M. 

 N. H. (8) iii, p. 259), namely, littledalei, has not been taken in our 

 limits, but only on the Pamir. I have however included it, as 

 well as dichrous. Anderson, from Kabul, in the following key : —
