they are distant from each other about two Unes. The forehead is 

 rather flat. The lower Hp is broad, with the extreme edge naked, 

 and rather thickly clothed with short hair on the chin, which be- 

 comes very thick on the throat. Immediately within the symphysis 

 menti is a small but distinct wart. 



The ears are rather small, oval-triangular, with a pretty uniform 

 outline, and with a kind of plait or crease on the basal front of the 

 inner margin, giving that part of the ear a slightly projecting lobe, 

 not however of sufficient magnitude to interfere materially with its 

 general uniformity of outline. The outer margin is not hollowed 

 out, but maintains a pretty regular curve, and has its basal portion 

 brought forward, in the form of a narrow rudiment of membrane, on 

 to the cheek, where it ends immediately under the eye. 



The tragus is short, rather broad, and of nearly uniform breadth, 

 with the end round. It has, as in all the other species of this re- 

 stricted group, an inward curvature. 



The wing-membranes spring from the base of the toes, and the 

 latter occupy about half the length of the entire foot. The os calcis 

 extends one-third of the distance from the foot to the tip of the tail, 

 which has its extreme tip free. 



The face is furnished with some tufts and lines of bristly hair. 

 Immediately in front of the eye may be noticed a tuft, consisting of 

 a few hairs, and on the gland of the upper lip is a similar one. 

 From behind the nostril proceeds a narrow band of fiue bristly hairs, 

 which curves downwards and backwards on the lip for a short distance, 

 and then taking an upward curvature, passes in front of the eye, and 

 is lost in the fur of the forehead. 



All the membranes, both above and below, have those parts con- 

 tiguous to the body, hairy, especially the interfemoral, on which it 

 extends more markedly than elsewhere. The part of the latter mem- 

 brane which is destitute of hair is smooth, and has about ten trans- 

 verse strongly dotted lines. 



Over the whole of the body the fur is very thick, soft, and rather 

 long. On the top of the head it is long enough to obscure the basal 

 half of the ears, and thus give the appearance of an elevated crown. 



Everywhere the hair is unicoloured, and of a black-brown colour 

 on the head and back, passing mto chestnut-brown on the rump. 

 Beneath it is similar in colour, but more strongly tinged with brown, 

 especially towards the pubal region, where it is reddish-brown. 



On examining the cranium, I find that its chief peculiarity consists 

 in its extreme shortness in relation to its other dimensions. In this 

 respect it more nearly resembles the cranium of Lasiurus novebora- 

 censis than that of any other species of Bat I have yet seen, but it is 

 even shorter than in that species. In its general conformation it 

 bears considerable resemblance to that of the common PipistreUe of 

 Europe, especially in the degree of elevation of the cerebral region ; 

 the arraugement of the dental series is more like that of the 

 XoctuJe Bat than that of the PipistreUe, but bears a still greater 

 resemblance to that of the Scotophilus Gouldii of Australia. Thus, 

 on examining the teeth of the upper jaw, they are seen to be arranged
