depth of the fork, and the greater proportion of transverse veins, in the 

 portion of the interfemoral membrane connected with the joint named, 

 tend, with other characters, to estabhsh this as a distinct species from the 

 last. 



VespertiUo Capensis, mihi. 



V. supra flavo-fuscus, subtiis flavO'ttlhus; membranis nigro-fusciSf 

 interfemorali longe ultra pedes extensd et postice acuminatd, uhi 

 caudcB est terminatio; auriculis indentatis extern^, et apicibus sub- 

 acutis, trago lineari, subfalciformi. /^ 9 . 



Above yellowish brown, beneath yellowish white; membranes black- 

 ish brown, the interfemoral one extending considerably beyOtid thp 

 feet and pointed behind, where the tail terminates; auricles indented on 

 their outer edges and with their tips sub-acute ; tragus linear and falci- 

 form ; head short, its sides and the muzzle bare and black, lips mar- 

 gined towards the angles of the mouth with strong brownish hair. 

 Length of body, an inch and three-quarters ; length of tail, three-quarters 

 of an inch ; expanse of wings, nine inches. 



This species has a strong affinity to the VespertiUo Temmmckii of Dr. 

 Horsfield, and perhaps when the two are accurately compared together 

 will be found to be the same, and the trifling apparent differences to be 

 dependent upon changes which take place during the preparation of spe- 

 cimens. In the Cape example the posterior part of the interfemoral 

 membrane is inclined to a semicircular form, whilst in that of Java it 

 will be found to be more acuminated. Other slight differences are also 

 observable, independent of those of colour and size.
