On a fiew Species of Monkey. 521 



Tlie type^?L dried skin, is No. 87.4. 18. 1 of the British 

 Museum collection, and was taken at Orotava, TenerifFe, by 

 Seii. R. Gomez on the 3rd of April, 1887. 



The large wings of this bat mark it as distinct from any 

 other known Flecotus. 



Plecotus puch, sp. n. 



This bat resembles P. auritus of Britain and is of similar 

 size, but has a quite distinct skull. 



The colour of the basal portions of the hairs is everywhere 

 dusky: the tips are, above between Ridgway's "Isabella 

 colour " and " broccoli-brown," below whitish ; the upperside 

 has a grizzled appearance. 



The skull, as compared with Central European examples 

 {? austriacus of Geoffroy), is smaller, but about equal in size 

 to those from England. The facial region and palate are, 

 however, narrower and the backward extension of the latter 

 less pronounced ; the auditory bullae are larger. 



The dimensions of the type (in millimetres) are as 

 follows : — 



Head and body 40*; tail 50*; ear 41 * ; ear from the 

 notch 32; tragus 16; thumb without claw 8; longest digit 

 60; basal joint of tifth digit 32 ; basal joint of second digit 

 34*5 ; forearm 38 ; tibia 17 ; hind foot without claw 8. 



The type is a skin, No. 5. 1 1. 19. 1 of the British Museum 

 collection. It is a male taken at Murree, N. India, altitude 

 7500 feet, by Capt. E. T. F. Birrell, R.A.M.C, on the 20tli 

 of August, 1905. 



This bat approaches more closely to European Plecoti 

 than to others in the Museum from Tor, Sinai, and from 

 Ladak. The latter are in both cases larger, in which 

 character they agree with two from Hokkaido, Japan. They 

 are, perhaps, referable to Hodgson's P. homochrous.
