42 Dr. N. Severtzoflf on the Mammals of Turkestan. 



4. Vesperugo akokomuli, Temm., var. almatensis, Sev. 



Is common in the north-eastern portion of Turkestan, viz. 

 about the Semiretchje, the upper part of Narin, Aksay, Copal, 

 and Vernoe. As to its vertical range, it is found at about the 

 same altitude as the foregoing species. 



A male specimen, obtained at Vernoe in May 1865, some- 

 what resembles V. abramus, Temm., in the shortness of its 

 muzzle ; but the colour, the form of the ears, and all other 

 charactei's are like those of V. akokomuli. The ears are very 

 wide at the base ; the belly towards the tail is white, forming 

 a semilunar white patch. It mostly inhabits the houses. 



Very remarkable is the distribution of this Japanese form ; 

 but the circumstance of the characters of two Japan species 

 being found in one specimen from Vernoe shows that the ori- 

 ginal race from which the two Japanese forms have their 

 origin is a Central-Asian species. 



5. Plecotus aurituSy var. hrevimanus. 



Found only in the north-eastern portion of Turkestan, and 

 very rare. It has been obtained at an altitude of from 4000 

 to 8000 feet. 



The only specimen obtained by me I met with at the Djan- 

 bulak, on the southern side of the Kuraminsk mountain-chain, 

 between Tashkent and Hodgent. It was at first taken by me 

 for a new species, P. leucophceus \ but this specimen quite 

 agrees with the description of P. hrevwianus^ and, like it, 

 differs from the real P. auritus in the shorter ears and lighter 

 colour — characters which, according to Blasius,are not constant. 

 The true P. auritus has been found in Turkestan about Vernoe, 

 at a height of about 6000 feet ; the real P. hrevimanus only in 

 Sicily ; and specimens intermediate between the two in Sicily 

 and Italy. But still, on these short diagnoses, I do not venture 

 to say for certain that my P. leucophceus is identical with hrevi- 

 manus without having a sufficient number of specimens for 

 comparison ; but its geographical relationship to the Turkestan 

 P. auritus is the same as that of the European P. hrevimanus 

 to the European P. auritus ; only no intermediate specimens 

 have yet been met with. 



6. Plecotus leucophceus, n. sp. 



Has been found in the north-western portion of Turkestan, 

 as stated above.
