Remarks. — This species is readily distinguishable among the 

 European members of the genus Pipistrellus by the peculiar form 

 of the tragus, apart from its very pronounced cranial and dental 

 characters. Its colour gives it a superficial resemblance to 

 Ejptesicus nilssoni, a likeness that is so heightened by the exces- 

 sively small size of the anterior upper premolar that the animal 

 has been once and perhaps twice described as a member of the 

 genus Eptesicus*

* This is certainly the case with the Vespertilio ochromixtus of Cabrera. 

 In the paratype of this species (B.M. no. 8. 7. 23. 1), which I carefully 

 examined before removal of the skull, in company with Mr. Knud Andersen, 

 no trace of the small premolar could be found. When the skull was cleaned, 

 however, the presence of the tooth in its normal position was revealed, 

 thus showing the animal's true identity. It. seems not improbable, so far 

 as can be judged from the original description, that Satunin's Vesperugo 

 caucasicus (Zool. Anzeiger, xxiv, p. 462, August 5, 1901) was based on 

 similar specimens.
