283 On new Glossophagine Bats. 



This forms the second new genus of bats tliat Mr. Under- 

 wood has discovered, the first having been Glypkonycttris, 

 described by me in 1896. 



In studying this bat tiie following species also proves to 

 need description : — 



Choeronycteris Godmani, sp. n. 



Size, as judged by forearm, about as in C. minor ^ but 

 owing to the great reduction of the muzzle the skull is con- 

 spicuously smaller. Snout less heavily whiskered than in 

 (J. mexicann. Face small and pointed, very different to the 

 long face of the other species. Nose-leaf triangular, about 

 as bioad below as high. Ears in shape and proportionate 

 size about as in C. mexicana, but, owing to the shorter face, 

 they reach when laid forward to the eye ; antitragal lobe low, 

 rounded, the notch behind it shallow. Calcar fairly long, 

 reaching when laid against the fout to the middle of the 

 claws. 



Fur short and close, confined to the body and the fleshy 

 parts of the forearms and thighs. Its colour (in spirit) appears 

 to be a dull uniform brown above and below. 



Skull differing conspicuously from that of the other species 

 of the genus by its disproportionally small, delicate, and 

 slender muzzle, the brain-case being nearly equal to that of 

 C. minor, while the muzzle is not two thirds its size in that 

 species. The measurements of the palate and tooth-rows 

 given below afford evidence of this characteristic. Hinder 

 edge of palate level with middle of glenoid surface. Ptery- 

 goid processes bulbous and reaching backwards, as in G. mexi- 

 cana and minor, to the bullae. Basioccipital excavated 

 laterally, but the median ridge is not continued forward on to 

 the sphenoid, which is quite flat. Ramus of lower jaw very 

 slender, its vertical height behind pi about 08 millim. 

 Teeth very delicate, with wide gaps between them, their 

 shapes as in C. minor; a large vacant space behind the upper 

 canines. Upper incisors subequal, in pairs, widely separated 

 in the middle line. 



Dimensions of the type, measured on the spirit-specimen: — 



Forearm 33* 5 millim. 



Bead and body 47; tail 7; nose-leaf 3-0 X 3-0; ear 9-5; 

 third finger, metacarpus 32, first phalanx 13, second phalanx 

 17 ; fittli finger, metacarpus 28, first phalanx 8, second 

 phalanx 9'3 ; lower leg and foot, s. u. 18-5, c. u. 19-8 j 

 calcar 6*3 ; depth of interfemoral in middle line 12-0. 



Skull: greatest length 19*6, basal length 17; breadth 

 across brain-case 8 ; breadth of muzzle at anterior premolar 8;
