6 Mr. J, E. Gray on some new Bats collected 



tail cylindrical, elongate^ rather more than half free; feet 

 with a smaD round hinder pad. The pads of the great and 

 little toes rather large, covered with white hairs, which are 

 curved and rather dilated at the tip. Tragus rather large, 

 truncated, with two or three small lobes on the edge ; lobule 

 large, rather obliquely truncated at the tip, and with a shght 

 notch in front of the lower edge. Plate I. fig. 3. 



Hab, Cuba. ^' Sent up from the interior of the island, 

 where it was found in the hollow of a tree.'^ MacLeay, 



The head and nose of this species are very like the N, pli- 

 catus of India, but the lips and ears are much larger in pro- 

 portion, and the lobule of that species is higher, rounded 

 above, and without any notch at the base of the front edge. 

 Like that species, the thumb has a large circular callous pad 

 at its base, which agrees with Spix's character of his genus 

 Thyroptera, and induces me to believe that his genus will 

 only prove to be a synonym of Nyctinomus, 



The species of Nyctinomus at present known may be thus 

 divided : — 



A. Ears united at the base in front on a common tubercle. 

 Lobule high, rounded, without any notch at the front of 

 the base ; ears large ; tragus distinct, N. plicatus. 

 Lobule elongate, truncate above, with a notch at the front 

 of the base ; ears very large ; tragus very small. N. ma- 

 crotis. 



B. Ears close but separate at the front of the base. 

 Lobule semi-ovate, not notched in front ; tragus subqua- 

 drate, rather large, N. nasutus. 



Molossus tropidorhynchus. Gray, Mol. velox, Horsf. Zool. 

 Journ. vii. 237. Upper lip with a roundish tuft of close 

 slender hooked hairs under the nostrils ; muzzle angular with 

 a central longitudinal and a transverse slightly crenated keel ; 

 throat pouch large ; tail rather slender, tapering, more than 

 half inclosed in the membrane. 



Hab. Cuba. " Very common in the city of Havana." Mac 

 Leay. 



This species is very like Dysopes velox, but is smaller, and 

 differs in having only a single central ridge between the nos- 

 trils, which is forked and sends a transverse ridge over each.
