444 MR. G. E. DOBSON ON A NEW BAT, [Juiie 1, 



conch is obtusely rounded off and the emargination beneath it ex- 

 ternally is very shallow ; the inner margin of the conch is also more 

 convex, so as to project forwards as far as the extremity of the muzzle ; 

 above the nasal apertures the superior surface of the face terminates 

 by forming a small rounded wart-like process covered on all sides, 

 except in front, by thick-set hairs, in front it is naked with a pro- 

 jecting upper margin ; the lower lip is reflected outwards as in iV". 

 stramineus, but beneath it, in front, there is, as in the species of 

 Chilonycteris (Phyllostomidse), but much less developed, a small 

 horizontal cutaneous projection, like a second lower lip. 



Wings very like those of N. stramineus, but the wing-membrane 

 is attached high up, at the junction of the middle and lower thirds 

 of the tibia ; the interfemoral membrane, the tail, and the calcanea 

 are exactly similar to the same parts in that species. 



Foot extremely small, appearing scarcely half the size of that of 

 N. stramineus. Fur above pale yellowish brown at the base, the 



Head of Natahis micropus. 



terminal half reddish or chestnut-brown ; beneath pale yellowish 

 brown throughout. This is the appearance of the fur in alcohol. 



Upper incisors like those of N. stramineus, but the outer incisor 

 on each side, instead of exceeding the inner in cross section, is 

 equal to or even smaller than it ; upper premolars as in that species, 

 but the second premolar is still more widely separated from the third ; 

 lower incisors, premolars, and molars also quite similar. 



Length, head and body, 1-.5 inch ; tail l-8j ; head 0-65 ; ear 0"5 ; 

 forearm I'S ; thumb 0*15 ; third finger — metacarpal 1-5, 1st. ph. 

 0'55, 2nd. ph. 0*7 ; fourth finger- — metacarp. 1*1, 1st. ph. 0*3.5, 2nd 

 ph. 0-35; fifth finger— metacarp. 1-05, 1st. ph. 0-35, 2nd. ph. 0-35 ; 

 tibia 0-65 ; foot 25. 



Hub. Environs of Kingston, Jamaica. 



Natalus lepidus, Gervais, is still smaller, has a differently formed 

 tragus, and is also easily distinguished from both this species and 

 N. stramineus by its dentition. (See Catal. Chiropt. Brit. Mus. 1 8/8, 

 p. 344.)
