depoiiil, in some Je^^ree at least, upon the coloui of the fur. 

 I have referred above to tlie sliglit importance of tliis character 

 in determining species ; and the following remarks occur in 

 my description of P. atin'tu.^ (at p. S4, * Monograph of the 

 Asiatic Chiroptera '^: — "Examples from Northern Africa and 

 sandv districts in the neighbourhood of the Mediterranean and 

 Caspian seas are much paler in colour throughout than those 

 fn>m moister countries. This I have frequently observed in 

 specimens of bats brought from desert regions."' 



Many specimens of a Plicofus with very light- coloured fiir, 

 but not otherwise distinguishable from P. aun'tuSf were 

 obtained by Dr. Stoliczka at Leh.

Rhinolophus eurtfaifj Blasius, has not yet been recognized 

 by other z<x»logists fn>m any part of Asia north of the Hima- 

 layas; but R. t^rrum-<qu{nuin. which it resembles very closely, 

 is abundant in the Himalayan region. Therefore I would 

 suggest that this species, which has been recognized as B.

The body is rather depressed ; the mantle ample, extending 

 over the head and the foot and bearing sofit conical papillse. 

 The dorsal tentacles are short and laminated, and retractile 

 within sheathless cavities. The branchia are simply lami- 

 nate, form a cup ronnd the anus, together with which they 

 are contained in a common mantle-cavity, the wall of the
