The fur on the back is apparently atubley grey next the skin, and 
pale ashy grey externally, and on the under parts the hairs are grey 
at the base and whitish at the point. The incisors are aS the 
pair of incisors on either side of upper jaw nearly equal. The fore- 
head is convex, and separated from the muzzle by a transverse de- 
pression: the muzzle somewhat produced and pointed, the mesial 
portion above and in front naked, the naked portion above extending 
about two lines from the tip, and separated from the somewhat 
swollen cheeks by a longitudinal groove on each side: between the 
nostrils, which are widely separated and pierced almost laterally, is 
a shallow groove. ‘The lips have small scattered hairs, excepting at 
the tip, where they are naked; on the chin is a naked wart some- 
what removed from the apex. ‘The ears are largeish and rather nar- 
row, pointed, and have the hinder margin nearly straight. The 
tragus is narrowish, attenuated, and pointed at the apex. The wings 
are ample, and the membranes encroach on the back so as to reduce 
the portion covered with fur to a narrow strip of about half an inch 
in width ; they extend along the hind-leg to the heel only ; the thumb 
is comparatively long; the “hind- foot very large, and having the toes 
equal, excepting the outer one (according to “the natural position of 
the foot, but the toe corresponding to the inner toe in most other 
animals), which is rather shorter. The interfemoral membrane is 
moderately ample, and does not extend quite to the tip of the tail, 
a portion of about one line in length being free. ‘The heel-cartilage 
is very long. 
In the large size of the hind-foot the present species approaches 
the V. Hasseletii of Temminck’s Monograph, but it does not appear 
that that species has the wings encroaching on the back as in V. ma- 
crotarsus; the ears are much larger, the thumb also larger, tail 
longer, &c. The proportions, as compared with those of M. Tem- 
minck’s V. macrodactylus and V. brachypterus, differ considerably, 
though both these species have the hind-foot large; the larger ears, 
longer thumb, and more ample wing will serve to distinguish it. 
VESPERTILIO PELLUCIDUS. Vesp. vellere longo, pallidé rufo, cor- 
pore subtis cinerascenti-albo ; alis fuscis, pellucidis ; auribus mag- 
nis, apice acutis, postice emarginatis ; trago elongato, attenuato ; 
rostro producto, depresso, subacuto.
