the intert'emoral membrane. The dentition is I -^ C -^- 1*1^^ '2 ■'^-'-3' 

 with another upper incisor in the young. It is African, Asiatic, 

 and Australian. 



This genus appears to be connected with Vesjjcruffo by Mr. 

 Dobson's proposed genus, or sub-genus as it is generally held to he, 

 Scotozous} The genus Nycticejus, founded for the inclusion of 

 Scotozous dormeri, an Indian species, should, according to Dr. 

 Blanford, replace on grounds of priority the name Seoto2)I(ihcs. 

 But as this name {Nycticejus) is one introduced by Eafinesque, 

 whose work was so uncertain and untrustworthy, it seems prefer- 

 able to retain the better-known name of tScotophilvs, introduced 

 by William Elford Leach. 



The genus Chalinufohus - has short, Ijroad ears with an 

 expanded tragus. A distinct fleshy lobule projects from the 

 lower lip on either side of the mouth. The tail is as long as the 

 head and the body. The dental formula is I j^ C ^ Pm -|- or }, M -|. 

 The genus occurs in Africa, Australia, and New Zealand ; but the 

 African species, wdth diminished premolars and pale coloration, 

 have been distinguished as Glciuconyctrris. 



Fam. 4. Emballonuridae. — The Bats belonging to this family 

 haye no nose leal'. The tragus is present, but often yery small. 

 The ears in this family are often united. There are two phalanges 

 in tlie middle finger. The tail is partly free, either perforating 

 the interfenioral memlirane and appearing upon its upper surface, 

 or prolonged beyond its end. The face is obliquely truncated in 

 front, the nostrils appearing beyond the lower lip. 



Uinhallonura is Australian, Oriental, and ]Mascarene in range. 

 The ears arise separately, and there is a fairly developed and 

 narrow tragus. The tail perforates the interfenioral membrane. 

 The dental formula is I | C ^ Pm f M -|. 



Wiinojwina has the ears united ; the incisors are reduced by 

 one on each side of each jaw, and the premolars are similarly 

 reduced, but only in the upper jaw. 



Noctilio is an American genus of two or three species, which has 

 one pair of markedly large upper incisors, which completely con- 

 ceal the outer pair. On these grounds this Bat was remoyed from 

 its allies and placed by Linnaeus among the Eodents, an instance 

 of the disadvantage of the artificial scheme of classification. The 

 species named N. leporinns has been shown to feed upon fish.
