" Mammals of Turkestan.''^ 131 



1. Vesperugo turcomanus^'EiYex&m. (Severtzoflf), =Vesperugo 

 serotinus, Schreber, 



V. turco7nanus, Eversm., was founded on a specimen of 

 V. serotinus with buff-coloured fur. Individuals of this species, 

 of V. Kuhlii, V. pipistrellus, Plecotus auritus, and of other 

 species of bats inhabiting dry sandy districts have the fur of 

 a permanently pale colour, imitating, as it were, the prevailing 

 light colour of the ground. The same remark seems to apply 

 equally well to other species of mammals and to birds. 



Specimens of this species were obtained by Dr. Stoliczka 

 in Kashmir. 



3. Vesperugo Blythii, Wagner (Severtzoff),= Fesperw^o 

 ahramus, Temminck. 



The name V. Blythii was given by Wagner to a specimen 

 of V. ahramusj Temm., very imperfectly described by Blytli, 

 which he (Wagner) had not seen, but which he nevertlieless 

 thought Blyth had confounded with anotlier species. 



4. Vesperugo akohomuU, Temm., var. almatensis, Severtzoff, 

 = V. ahramus, Temm. 



Tliis variety appears to have been founded on colour alone — 

 a very unreliable character, as I have frequently pointed out, 

 in determining the species of Chiroptera. 



The species most probably alluded to under the above two 

 names (nos. 3 & 4) by Dr. Severtzoff is V. pipistrellus, of 

 which many specimens were collected by Dr. Stoliczka at 

 Yangihissar. It is readily distinguished from V. ahramus by 

 the deep emargination in the upper half of the outer margin 

 of the ear. V. ahramus has not been found, so far as I can 

 determine, north of the Himalayas. 



5. Plecotus auritus, var. hrevimanus, ^Qwyn^ (Severtzoff), 

 = P. aurituSj L. 



P. brevinianus, Jenyns, was founded on an immature spe- 

 cimen of P. auritus, L., in which the extremities of the pha- 

 langes were not completely ossified and the shafts had not 

 attained their full length.

6. Plecotus leucopJicBus, n. sp., Severtzoff, =?P. auritus, L. 



No description accompanies this name ; but, judging from 

 the etymology of the specific title, the species appears to
