222 Zoological Society : — 



The thumb has the same long terminal phalange and short basal 

 one observable in the last two species. The feet are large in rela- 

 tion to the size of the animal. The membranes of the wings extend 

 a little way beyond the extremity of the tibia, but do not reach half- 

 way along the footy exclusive of the toes. The extreme tip of the 

 tail is slightly exserted, and very pointed. 



The fur of the head extends down the forehead nearly to the 

 nose ; the face is moderately hairy, and has a tuft of fine long hairs 

 immediately in front of the eye. The basal part of the hinder sur- 

 face of the ear is hairy, some of the hair projecting beyond the inner 

 margin so as to be visible from the front. Two patches of short ad- 

 pressed hair of a fine nature line the inside of the ear, one of them 

 extending from the front margin to near the tip, and the other 

 fringing that part of the margin nearest to the root of the tragus. 

 The latter part is sparingly covered with short adpressed hairs on 

 its exposed surface. 



The muzzle and greater part of the face are brownish-black. The fur 

 of the upper parts is of four colours— dark at its root, then yellowish- 

 brown, succeeded by dark brown, and tipped with white. Towards 

 the hinder parts of the body, and on the interfemoral membrane, the 

 yellowish colour gives way to the brown, and the fur is wholly of 

 the latter colour, tipped with white. The throat is light yellowish- 

 brown, passing into dusky-brown on the breast. On all the under 

 parts the fur is of a faded brown colour for the greater part of its 

 length, but near the tip it becomes a little darker, and is finally 

 tipped with dirty buff colour. The fur on the membranes beneath 

 the humerus is in some examples of the same tricolour as the under 

 parts of the body, but more frequently it is of a uniform brownish- 

 yellow hue, as is that beneath the fore-arm, and that at the base of 

 the fingers. 



The hairy portions of the membranes are reddish-brown ; the 

 remaining parts very dark brown. 



The variations in colour to which this species is subject depend 

 upon the tint of the brown colour near to the tips of the hairs. In 

 one example in the British Museum, this part of the hair is of a 

 light red colour, inclining to pinkish, and takes up a much greater 

 space than usual in each hair, the dusky at the base being there 

 very much reduced. In this specimen the black of the face and the 

 yellowish colour of the throat are scarcely observable ; and this, with 

 the red colour, gives it, at first sight, a great resemblance to the 

 L. noveboracensis. 



The colour of the fur is an index to that of the membranes— in 

 this instance a reddish-brown. 



The dentition has not been well examined, but the incisors are 

 similar in number and shape to those of the last two species. 



Five examples have been examined in drawing up the above de- 

 scription, and these are all so remarkably uniform in size, that it 

 appears unnecessary to give the dimensions of more than two, those 

 presenting the greatest disparity being selected.
