This striking new Bat, which I have named after Dr. Wollaston, is related to 

 H. muscinus, another Papuan species, but is distinguished by its posterior nose-leaf 

 being duplicated, and by the greater inflation of the frontal region of its skull. 



The definite duplication of the transverse nose-leaf is a character practically unique 

 in the genus, the nearest analogue to it being found in the African //. caffer, which 

 has some inconspicuous convexities in the positions of the supplementary posterior 

 crests of H. wollastoni. The additional transverse crests in H. pratti and //. lylei form 

 a structure of quite a different character. 



This is possibly the bat obtained on the Noord River by Lorentz, and determined 

 by Jentink as H. muscinus. But the latter may really occur, as its type locality, the 

 Fly River, is by no means very far off.

This fine species is by far the largest member of the genus, the next in size, 

 E. semicaudata, having a skull-length of only 15-5 mm., as compared with 18-7 

 in E. furax. It is also remarkable for the unusual expansion of the facial region of 

 its skull.
