Species of this genus are found in both hemispheres. To those of the 

 Western hemisphere belong two bats, figured in Buffon, x. PI. 19, figs. 2, 

 3, which ScHREBER and Gmelin united under the name of Vespertilio 

 molossiis, but which are imperfectly known. Also Molossus obscurus 

 Geoffr., Dysopes obscurus Temm. 1. 1. PI. 22, fig. 2, Guerin Iconogr., 

 Mamm. PI. 7, fig. 4 (fig. of the head, the skull and the teeth), from Brasil 

 and Surinam, &c. and many others. — In Africa is found Dysopes Geoffroyl 

 Temm. &c. (see also the new species made known by Peters from Mosam- 

 bique) ; on the coast of Guinea this genus has not hitherto been observed. 

 — In Asia Dysop)es tenuis Temm. 1. 1. PI. 19 bis, &c. ; in Euroj^e Dysopes 

 Cestonii, Dinops Cestonii Savi, Bonap. Fauna Italica, xiv. (also in Africa, 

 if it does not differ from Dysopes JRujypeUii). 



In one or two species from India the pollex of the hind feet is remote 

 from the other toes and provided with an obtuse round nail and many 

 bent, stiff", long hairs. On such is founded the genus Cheiromeles of HoRS- 

 FIELD. Sp. Cheiromeles torquatus Horsf. Zool. Researches, No. viii., Dy- 

 sopes chiropus Temm. 1. 1. PI. 17. — Cheiromeles caudatus Temm. Monogr. 11. 

 PI. 66, 67 ; from the Sunda Islands. In these animals there is found in 

 the axilla and on the front of the breast a glandular sac, of which the fat, 

 brown secretion diffuses a penetrating odour. With the exception of the 

 strong hair of the toes, these animals are covered by a nearly hairless 

 skin. 



Stenoderma GeOFFK. 



A genus unknown to me; tail none, ears separate, small. Comp. 

 Desmar. Diet, des So. nat., Tom. 50 (1827), pp. 489, 490, PI. Mammif. 

 16, fig. 2. 



Note. — Genera A'ello and Celmno Leach as doubtful are more 

 safely omitted.
