Although not of the showy character of the new Petouriatn 

 and the new genus of squirrels, tbis little animal is of very 

 special interest, as it confirms the division of the members of 

 the Uropsilinffi into three genera — a division about whicli I 

 felt most diffident. The identity of the external characters 

 and of the skulls, even when combined with the differences 

 in the dental formulae, made the division one of some doubt, 

 for it seemed possible that the formulae might be unusually 

 variable. This series, therefore, all absolutely agreeing in 

 formula with Nasillus — a genus of which I only had one 

 specimen before, — is of much value as confirming the 

 characters used. 



As a species N. investigalor is readily distinguishable from 

 N. gracilis by its larger skull. The locality of the latter is in 

 a different faunal area, much further eastwards, and at an 

 altitude of only 4000'.
