1875. ] MR. G. E. DOBSON ON NEW SPECIES OF BATS. 471 
developed, the upper lip symmetrically thickened. Ears short; the 
distance between the base of the inner margin of the ear-conch and 
the termination of the outer margin near the angle of the mouth is 
equal to the distance from the base of the inner margin to the summit 
of the ear; integument forming the conch very thick, especially the 
lower half of the outer side; tragus short, broad above, narrow 
opposite the base of the inner margin. 
Feet wholly free from the wing-membrane, which is attached to 
the tibia a short distance above the ankle; this and the shortness of 
the phalanges of the third and fourth fingers cause remarkable 
narrowness of the wings. Postcalcaneal lobe small, termination of 
caleaneum indistinct ; tip of tail free. Fur dark brown throughout ; 
integuments and wing-membrane dark brown or black. 
The muzzle in front of the eyes, both above and beneath, is almost 
naked ; and the distribution of the fur upon other parts is similar to 
that in V. noctula. 
The upper incisors are similar to those of V. noctula; but the 
second upper premolar is separated by a small space from the 
canine, through which the small first premolar may be seen from 
without. 
Length (of an adult male preserved in alcohol), head and body 
2"-35; tail 1:7; head 0”:75; ear 0-6; tragus 0-25 x 0'°15; 
forearm 1°55; thumb 0-32; second finger 2'°6; fourth finger 
1°65; tibia 0'°55; foot and claws 0'"45. 
Hab. Sarawak, Borneo. 
Type in the collection of the British Museum. 
6. Ears longer than broad, triangular; tragus reaching its greatest 
width below the middle of the inner margin, longer than broad ; 
no postcalcaneal lobule; wings from the base of the toes; pre- 
molars 2s Subgenus A/lodus, Ptrs. 
2. VESPERUGO PULCHER, D. sp. 
Crown of the head slightly elevated above the face-line; muzzle 
shaped more like that of some species of Vespertilio (V. emarginatus, 
e.g.),and the glandular prominences between the nostrils and eyes less 
developed than in most species of Vesperugo. Lars about four fifths 
the length of the head, the ascending inner margin straight or 
faintly convex, the upper half of the outer margin slightly concave, 
terminating in a line directly below the eye, but on a lower level 
than the angle of the mouth; tragus nearly half the length of the 
ear, shaped like that of V. serotinus. 
Posterior margin of the interfemoral membrane festooned with 
distinct papille arranged like the teeth.of a comb. 
Fur above sienna-brown, with shining tips, beneath wholly pure 
white; the dark-coloured fur of the back does not pass beyond a 
line connecting the angle of the mouth (when the head is extended) 
and the under surface of the humerus. Interfemoral, antebrachial, 
and wing-membranes between the humerus and femur white; the 
remaining parts of the wing-membrane pale brown.
