28 MAMMALIA PRIMATES. [VESPERTILIO. 



surface of the same membrane naked. Fur long and silky, brownish gray 

 on the upper parts, paler beneath; the hair every where dusky at the 

 roots. 



A common and generally diffused species, resorting principally to the 

 roofs of houses and churches. Flight swifter than that of the Pipis- 

 trelle. In the living animal the ears are generally curled, the bend being 

 directed outwards . when at rest they are sometimes wholly concealed 

 beneath the fore-arm, the tragus alone remaining erect. 



37. V. brevimanus, Jenyns. (Lesser Long-eared Bat.) 

 Ears not double the length of the head ; tragus oval- 

 lanceolate : fur reddish brown on the upper parts ; yellowish 

 white beneath. 



V. brevimanus, Linn. Trans, vol. xvi. p. 55. pi. 1. f. 2. 



DIMENS. Length of the head and body one inch six lines ; of the 

 head seven lines ; of the tail one inch two lines ; of the ears one inch ; of 

 the tragus five lines and a half ; breadth of the ears five lines ; of the 

 tragus two lines ; length of the fore-arm one inch two lines ; of the 

 thumb three lines : extent of wing six inches six lines. 



DESCRIPT. Similar to the last in general appearance, but much 

 smaller, and differing in its relative proportions : ears shorter with respect 

 to the head, and rather narrower at the extremity; tragus relatively 

 longer: bones of the hands much shorter: thumb somewhat longer: 

 tail the length of the fore-arm ; the tip more exserted from the inter- 

 femoral membrane, and terminating in a fine point. Fur on the upper 

 parts reddish brown, presenting a marked contrast with that on the 

 under which is yellowish white ; the hair everywhere of the same colour 

 throughout its whole length, and not dusky at the roots as in the last 

 species : ears and membranes dusky with a tinge of red. 



A new species first described by myself in the Linnaean Transactions 

 as above quoted. Only one individual has as yet occurred, which is a 

 female. It was found adhering to the bark of a pollard-willow, in 

 Gruntey Fen in the Isle of Ely. 



(3. BARBASTELLUS, Gray.) 



38. V. Barbastellus, Gmel. (Barbastelle.) Ears shorter 

 than the head, broad, triangular, notched on their external 

 margins ; tragus semicordate : fur black, with the tips of the 

 hairs grayish white.

 Mont. Linn. Trans, vol. ix. p. 171. 



DIMENS. Length of the head and body two inches; of the head seven 

 lines and a half ; of the tail one inch nine lines ; of the ears five lines ; of 

 the tragus three lines and a half; breadth of the ears five lines; of the 

 tragus one line and a half; length of the fore-arm one inch four lines and 

 a half; of the thumb two lines and a half: extent of wing ten inches 

 three lines. 



DESCRIPT. Muzzle short and obtuse, somewhat swollen at the ex- 

 tremity ; a naked space above the nose extending up to the ears, sunk 

 and hollowed out in front, with the nostrils placed in the cavity ; on each
