muzzle they would open sublatcrally ; were the specuTaen taken 

 from the spirit in which it is preserved and dried, it is probable that 

 this would be the case. In the middle of the face is a kind of hol- 

 low, occasioned by the labial glands on each side being developed in 

 an upward direction, thus leaving a depression between them*. 

 Between the nostrils is a space of moderate extent, and but very 

 faintly emarginate. The ears are rather large, triangularly oval, as 

 broad at the base as they are long, and have their tips brought to a 

 rounded point ; about the middle of their outer margin they have 

 a distinct but shallow notch, below which is a lobular portion, as 

 in many other species of this group, but differing from all others 

 which I have seen in having a small but very well-defined notch about 

 its middle. These organs altogether are more like those of S. Kuhlii 

 than of any other species, but are larger, besides having the double 

 emargination just noticedf. The tragus is rather short and broad, 

 curved inwards, and with the end very much rounded ; on its outer 

 margin, near the base, is a projecting angular point, without any 

 accom.panying notch. 



The wing-membranes extend to the base of the toes, and the latter 

 are half the length of the foot. The thumb is moderate, with the 

 basal phalange much the shortest. The terminal vertebra of the 

 tail is free. 



The fur of the head extends forwards to between the eyes, and 

 thence in a narrow strip towards the nose. Over each eye is a wart 

 bearing a bundle of stiff hairs ; and a similar tuft springs from the 

 top of the labial glands ; the upper lips are also shghtly fringed with 

 similar hairs, most conspicuous about the corners of the mouth. 

 The remainder of the face, the cars, and the tragus are naked. The 

 fur of the back spreads on the vipper svirface of the interfcmoral 

 membrane, sparingly, for nearly half its length, as in S. Kuhlii, and 

 similarly to a small extent on the membranes near the sides of the 

 body. Beneath, the membrane immediately around the pubes is 

 dusted with very short hairs, more abundant on the vertebrse of the 

 tail than elsewhere. On the membrane contiguous to the sides of 

 the body, fur of a much longer kind extends, to a much greater de- 

 gree than in S. Kuhlii. 



On both surfaces of the body the fur is bicoloured : above, very 

 dark brown at the base, tipped with lighter and more rufous brown, 

 that on the membranes wholly of the latter colour ; beneath, it is 

 dark at the base, tii)pcd with paler brown, with less of the rufous 

 tinge than that of the upper parts. On the under surface of the 

 membranes the fur is uniformly of the same colour as the tips of the 

 hairs on the belly, but on the pubes it is paler. Membranes dark 

 brown. 



Such appear to be the colours of the fur, so far as can be gathered 

 from the examination of a specimen ia spirit ; but it is necessary to 



* III the Romk'ia calcarata of Dr. Gray the lip-glands are so much developed 

 as to leave a deep pit between them. It belongs to the present group. 



t 1 am here comparing a specimen in spiiit with others in skin, — a plan not 

 always attended with perfectly salisfaclory results.
