1842.] Notice of the Bat described as Taphozous longimanus. 785 



Is. Geoff.) ; secondly, the testes, in Taphozous (as in Megaderma, 

 and I presume Rhinolophus), are situate as in man and the monkey 

 tribe, whereas in the restricted Vesper tilio group they are placed 

 posterior to the anus, and in the Pteropodine section laterally to 

 the penis; this being a character which may help to indicate the 

 primary divisions of the family : the magnitude of the genitals is a 

 remarkable feature of the Vespertilionine subdivision generally, being 

 in some species quite inordinate ; but this is not the case in Tapho- 

 zous, wherein the penis wholly withdraws internally. Finally, it may be 

 remarked that the feet and tail of this genus have always a few scat- 

 tered long and slender hairs; and that the fore-arm is more than 

 usually curved at the basal third. 



The specimen of T. longimanus before me (an adult male) mea- 

 sures four inches and one-eighth to tail- tip, the membrane extending 

 five- eighths of an inch beyond ; expanse fifteen inches and a half, and 

 length of fore-arm two inches and three-eighths ; the tail an inch, capa- 

 ble of being wholly sheathed within the membrane, and of protrusion 

 for five-eighths of an inch : ears, measured internally, from base of 

 lowermost lobe, nine-sixteenths of an inch, and externally half an 

 inch : no upper incisors, as likewise in the examples of the three 

 other species described by me : the throat- sac particularly large, mea- 

 suring three-eighths of an inch wide, and thickly lined with a hard and 

 foetid exudation ; there is also a small circular second cavity, a 

 quarter of an inch posterior to the first, and yielding a similar secre- 

 tion ; this is also perceptible, but rather less developed, in T. fulvi- 

 dus: the fur is close and velvety, of a dark brown colour, slightly 

 grizzled with a pale hue at the tips, and not white at base as in T. 

 Cantori (which species has the throat-sac merely rudimentary) ; beneath 

 it is scarcely paler than above, but the throat is deeply tinged with 

 rufous : membranes brownish-dusky. 



The T. longimanus is stated by Gen. Hardwicke to be u common 

 in Calcutta, in dark store-rooms ; at night it frequents habitations, 

 attracted by the light of the candles and numerous insects." The 

 present specimen was shot in a rural situation, two or three miles 

 from Calcutta ; and, I may remark, rather late in the evening, when I 

 had been waiting some little time for an opportunity to discharge my 

 second barrel, prior to returning from a Bat-shooting excursion ;
