This bat was described by Hodgson ('Ann. Mag. Nat. Hist.' 1855), but
there is some doubt about it, and it has been classed as a _Lasiurus_
and also with _Scot. ornatus_ and _Vesp. formosa_, but Jerdon thinks
it a _distinct_ species. I cannot find any mention of it in Dobson's
monograph.

_GENUS HARPIOCEPHALUS_.

This is also the genus _Murina_ of Gray. Dr. Dobson explains his
acceptance of the former term in the following way: that he first
accepted _Murina_ on the score of priority in a paper showing that
_Harpiocephalus_ and _Murina_ must be united in a single genus; but
finding afterwards that Gray had founded _Murina_ on a specimen of
what he believed to be _Vesp. suillus_ (Temm.), but which was in
reality a specimen of a very different species from Darjeeling,
belonging to the same section of the genus as _Vespertilio harpia_
(Temm.) the type of his genus _Harpiocephalus_, it remained
therefore either to discard both names or to retain _Harpiocephalus_,
in which course he was supported by Professor Peters, to whom he
mentioned the facts.

Horsfield's genus _Lasiurus_ is included in this one, though Jerdon
considers it distinct from _Murina_.

Muzzle elongated, conical; _nostrils prominent, tubular; produced
beyond the upper lip_, opening laterally or sublaterally, emarginate
between; crown of the head scarcely raised above the face line; ears
thin, generally covered with glandular papillae; tragus long,
attenuated towards the tip, and inclined outwards; thumb very large,
with a large, strongly curved claw; wings around interfemoral
membrane very hairy.--_Dobson_.

Dentition: Inc., 2--2/6; can. 1--1/1--1; premolars, 2--2/2--2;
molars, 3--3/3--3.
