 By Oldfield Thomas. 



(PuUished by permission of the Trustees of the British Museum.) 



A FEW years ago, by the kindness of the authorities of the 

 Lisbon Museum, the British Museum obtained an example of 

 a peculiar Vespertilionine bat which had been received from 

 Angola, and whose systematic position seemed by no means 

 readily determinable. 



* Named, by request of Mr. Scott, in honour of F. W. Urich, Govern- 

 ment Entomoloo-ist in Trinidad.
