a very distinct midrib. In front of this leaf is a deep pit, which is 

 divided into two by a ridge which is continuous with the central rib of 

 the leaf; in the bottom of the pits thus formed are the nostrils, 

 which are small and ovoid. The septum between them is produced 

 anteriorly, and developed into a prominent and trifoliate fleshy ex- 

 crescence, which almost conceals the pits behind ; it has a central or 

 upright lobe, exhibiting outwardly a rounded footstalk surmounted 

 by a flattened top, the edge of the flattened summit being directed 

 upwards and having five very slightly prominent, but very distinct, 

 denticulations. Besides this central lobe there are two lateral ones, 

 which present a thin edge externally, and are continuous with each 

 other across the bottom of the central one. Where this horizontal 

 ridge runs across the central lobe, it is produced into a distinct point 

 or tubercle. On each side of the pits, behind the trifoliate leaf, is a 

 prominent, acutely conical, vertical projection about a line in length. 

 Below the trifoliate leaf is a transverse hollow, divided vertically by 

 a faintly marked septum, and below this is another transverse leaf, 

 forming the lower boundary of the hollow ; this leaf is but slightly 

 prominent, and has its ends curved upwards and terminating in two 

 warty excrescences contiguous to the two acute projections near the 

 nostrils. Below this is a flat space, constituting the upper lip. 



The lower lip has a large central space of a triangular form, which 

 is naked, and bounded laterally by a broad, smooth, and somewhat 

 elevated margin ; at its inferior point is a single small wart, and in 

 the middle, forming the front of the lip, is an enclosed granulated 

 space. 



The ears are as long as the head, broad and pointed, with the 

 lobular parts much developed, and extending forward almost to the 

 corner of the mouth. Tragus more than half the length of the ear, 

 tapering evenly to a subacute point ; near the base, externally, is a 

 prominent though somewhat obtuse angle, and above this a notch, 

 forming another angle, more acute, but less prominent, than the 

 other ; above the notch there is no angle, but a rounded and slightly 

 prominent part, and from this to the tip the tragus tapers pretty 

 evenly. The auditory opening is partly surrounded (posteriorly) by 

 a prominent fleshy ridge of a lobular form, which will fold forward 

 and completely close the opening. 



The longest finger is composed, as in all the Phyllostomidae, of 

 four phalanges ; the thumb has the two phalanges of nearly equal 

 length. The wing-membrane extends barely to the distal extremity 

 of the tibia, which it crosses over, in front, and is attached to the 

 base of the os calcis, somewhat as in the genus Natalvs. 



The tail is long, but composed of only nine joints, and extends 

 the whole length of the interfemoral membrane, as in the genus 

 Vespertilio. The feet are large, with the toes of equal length, and 

 the claws long and hooked. 



The skull in its general outline bears considerable resemblance to 

 that of Macrotis ; but the cerebral region is more elevated, and the 

 facial part more depressed. It is so much depressed just at the 

 posterior boundary of the nasal bones as to occasion a deep hollow
