or longitudinal pit. The nasal bones are very differently formed to 

 those of Macrotis, being very much arched from the fore to the 

 hinder part. The maxillary bones are considerably inflated between 

 the nasal opening and the orbits. All the facial part of the skull is 

 much less compressed than in Macrotis. 



Dentition:— Inc. i; Can. i=J ; Premol. g ; Mol. g=J|=32. 



The middle upper incisors are large, flat, and somewhat pointed ; 

 the lateral ones minute and pointed, and with a posterior lobe near 

 the base ; the canines are rather small and acute ; the first premolar 

 is very small, roundish, and with two cusps, the anterior one being 

 the most prominent ; the second premolar is very prominent, and 

 has the same carnassial form which is so common in the Chiroptera. 



The lower incisors are symmetrically arranged, rather small, and 

 flat, with their edges somewhat lobated ; the canines are slender, 

 straight, and with a distinct cingulum ; the first premolar is smaller 

 than the second, conical, acute, and with a slightly projecting poste- 

 rior lobe near the root ; the second premolar is rather long, angular, 

 and acute, with a well-marked cingulum. 



The tongue is thick and short, with six well-marked, transverse, 

 curved ridges, which are most distinct on the front part ; and behind 

 these are indications of others. All the upper surface of the tongue 

 is clothed with fine points, which are directed backward, like those 

 on the tongue of the Felidce. 



LONCHORHINA AURITA, n. S. 



Nearly the whole of the face is hairy, the hair having the same 

 quality and colour as that of the back ; the nose-leaf and fleshy ex- 

 crescences are naked, but a few hairs spring from the edges of the 

 former near the base ; ears hairy behind for three-fourths of their 

 length ; inside they have a distinct band of hairs on the inner mar- 

 gin, which does not extend further than three-fourths of their length 

 from the base ; and there is another, but smaller, band of hairs in- 

 side the lobular parts. 



The fur of the upper parts is nearly confined to the body ; but 

 there is a little scattered on the humerus and the contiguous end of 

 the forearm. Beneath, there is a little whitish hair powdered on 

 the membrane near the flanks and forearms. 



All the upper parts are light reddish brown, the fur nearly uni- 

 color ; beneath similar, but duller in colour, and paler on the pubes. 

 Cutaneous system dark reddish brown.
