* Allied to A. caudatus^ but the back, instead of being broadlv washed

The British Museum owes to Mr. St. George Littledale its first speci- 

 mens of this splendid marmot, and has since received others from the 

 St. Petersburg and Warsaw Mu-eums. These have been hitherto con- 

 sidered as identical with A. caudatus, Jacq., but the skins of this latter 

 received from Col. Ward and Mr. Whitehead show such constancy in 

 their larger size and possession of a broadly black-washed back that it is 

 evident tbat the Pamir species should be distinguished from them, and I 

 have had much pleasiu-e in naming it in honour of the well-known 

 e.xplorer who discovered it.
