the posterior upper molar little more than half the size of the second 
molar. The lower incisors are distinctly trifid, some even appearing 
to have a fourth lobe; they are not crowded, and form a regular semi- 
circle across the wide space between the canines. The lower premo- 
lars are also, like the canines, very slender and acutely pointed, the 
first premolar about half the size of the second.

This species has a general resemblance to Miniepteris schreibersi 
in the shape of the head and ears, in the shortness of the first pha- 
lanx and great length of the terminal phalanx of the longest finger, 
in the long and slender tail wholly contained within the interfemoral 
membrane; added to which the grey colour of the fur and corre- 
sponding size would cause specimens of this species to be readily con- 
founded, on a superficial examination, with specimens of the Euro- 
pean grey-coloured M. schreibersi. 
CHALINOLOBUS POENSIS. 
Kerivoula poensis, Gray, Aun. Mag. Nat. Hist. vol. x. p. 258(1842). 
Ears very similar to those of C. argentatus; inner and outer mar- 
gins convex, without a distinct tip, the outer margin forming a con- 
vex lobe m front of the base of the tragus, and terminating close to 
the angle of the mouth, the internal basal lobe forming a narrow 
lobule projecting backwards. Tragus similarly semilunate, even 
more curved inwards; the outer margin to the lip forming an arc 
nearly equal to two thirds of the circumference of a circle ; the inner 
margin slightly concave ; immediately above the base of the outer 
margin a prominent, acutely pointed, triangular lobule. So far as 
can be perceived from an examination of the dilapidated specimen 
which forms the type of this species, the lower lip has a horizontal 
lobe extending from the angle of the mouth to a point opposite the 
lower canine tooth, as in C. argentatus. Nostrils wide apart, sepa- 
rated by a slightly concave space nearly one tenth of an inch wide, 
and opening almost directly laterally. 
Thumbs and feet as in C. argentatus, and similarly black at the 
extremities, with black claws. Postcalcaneal lobe long and narrow, 
triangular, the apex of the triangle (which is placed about the middle 
of the lobe) supported by a small cartilaginous projection placed at 
right angles to the caleaneum. The tail appears to be wholly con- 
tained within the interfemoral membrane. 
Fur above dark at the base of the hairs, the extremities grey 
on the head and neck, and grey with a yellowish tinge on the back 
and sides; beneath similarly dark at the base, with greyish yellow 
extremities. 
The fur of the body extends upon the wing-membrane as far as a 
25*
