46 CHIROPTERA. 
Gray gives no specific description, and distinctly identifies his specimen with Geoffroy’s 
Glossophaga ecaudata (=Lonchoglossus caudifera, Geoffr.)1; so that it appears to me 
that his name cannot be revived. I therefore retain Professor Peters’s title as the first 
that can be certainly and exclusively applied to the species. 
One example of this apparently rare Bat was obtained by Mr. Salvin at Choctum ; 
and from it our figure has been drawn. 
12. CHOARONYCTERIS. 
Cheronycteris (Lichtenstein), Tschudi, Faun. Peru. i. p. 70 (1844). 
In this genus, as restricted by Professor Peters, the anterior molars are very narrow, 
without any distinct W-pattern, and the lower incisors and first upper premolars are 
deciduous. The muzzle is much produced; and the interfemoral membrane is well 
developed, the tip of the very short tail appearing on its upper surface. 
The species which occurs in Central America is distinguished from the Guianan 
Ch. minor, Ptrs., by its larger size, its longer and more emarginated ears, and by the 
calcaneum being shorter than the foot. The fur is dark brown, and the length of the 
forearm about 1":70. 
1. Cheronycteris mexicana. 
Cheronycteris mexicana, Tschudi, Faun. Peru. i. p. 72, pl. iii. fig. 3 (1844, descr. orig.)'; Peters, 
Monatsb. Ak. Berl. 1865, p. 354°; op. cit. 1868, p. 366°; Dobson, Cat. Chir. Brit. Mus. 
p- 510, pl. xxvii. fig. 54. 
Hab. Mexico (Brassart, Mus. Berol.*), Mirador (U.S. Nat. Mus.); Guatemata, Duenas 
(Salvin, Mus. Brit.*, Mus. Berol.) 
This species appears to be peculiar to our subregion, and is rare in collections. 
Besides Tschudi’s type, which was obtained in Mexico by Brassart, and is still preserved 
in the Berlin Museum, examples were obtained at Duefias by Mr. Salvin; and a 
specimen from Mirador is included in Professor Baird’s manuscript list above (p. 18) 
alluded to. 
13, ARTIBEUS. 
Artibeus, Leach, Trans. Linn. Soe. xiii. p. 75 (1822). 
Madateus, Leach, tom. cit. p. 81. 
Pteroderma, Gervais, Expéd. de Castelnau, Mamm. p. 34 (1855). 
The Bats of the genus Artibeus, with which we begin Professor Peters’s group of 
Stenodermata, have rather large ears, and a well-developed nose-leaf with a prominent 
middle rib ; the chin is marked with a median wart placed between two smaller ones,
