188 G. E. Dobson — On a new Vespertilio. [No. 2, 



nating rather abruptly ; behind, it passes on to the inter-femoral 

 membrane covering nearly half its surface and, leaving the posterior 

 half of the interfemoral membrane, the calcanea and metatarsi 

 bare, reappears on the back of the toes. 



Beneath, the fur of the thorax extends along the humerus to the 

 elbow joint, and as far as a line drawn from the elbow to the 

 knee joint the wing membrane is covered with a few scattered hairs ; 

 behind, the fur of the abdomen extends backwards upon the inter- 

 femoral membrane, rather densely at the root of the tail, but 

 quickly thinning out into a few, very short, scattered hairs which 

 extend over half its surface. The back of the ear is naked except 

 at the base, in front it is clothed with a few short hairs.

On first examining the specimen, from which the foregoing 

 description is obtained, I was inclined to believe it might be referred 

 to either V. formosus (Hodgs.), or V. rufo-pictus (Waterh.), but 

 a more careful comparison with the descriptions of these species 

 given by Mr. Tomes in the Ann. and Mag. Nat. Hist, rendered 

 it evident that it differs, not only in dentition, but also in several 

 other important characters, as the form of the tragus, the position 

 of the emargination on the outer edge of the ear, the distribution 

 and colour of the fur, &c.
