. 
Two new Asiatic Bats. 285 
lips divided in centre. Palate-ridges numerous, closely set, 
about 17-19 in number, but irregular, not quite corresponding 
on the two sides; the posterior half of them divided in the 
centre by a median groove; their pattern widely different. 
from that of any species of the Cynopturus group, or, indeed, 
any other figured in Anderson’s Catalogue, but most re- 
sembling—allowing for the wide difference in number—those 
ot Nyctimene cyclotis (p. 687), though all are equally bowed, 
instead of there being one or more straight ones anteriorly. 
Colour very like that of D. spadiceus, brown above and on 
the sides, dull whitish on the chest and belly. Yellowish 
area on shoulders of rather larger extent. But the face is not 
so markedly blackened. 
Skull larger and heavier throughout than in spadiceus, the 
zygomatic spread especially netable. Supraorbital foramina 
similarly minute. 
Canines long and strongly grooved. — Posterior basal ledges 
of all teeth rather less developed than in the allied species. 
Height of premolars greater. 
Dimensions of the type (a spirit-specimen) :— 
Forearm 82 mm. 
Head and body 118; tail 18; ear 19x10; third finger, 
metacarpal 58, first phalanx 38, second phalanx 47; lower 
leg and hind foot (c. u.) 48. : , 
Skull: greatest length 40°2; condylo-basal length 37 ; 
zygomatic breadth 27-4; orbit to nares 9°2; interorbital 
breadth 8°6 ; across postorbital processes 15-7 ; intertemporal 
breadth 6°6; mastoid breadth 16; palatal length 20°5; 
maxillary tooth-row 14:2. 
Hab. Lebong Tandai, Upper Ketaun River, about 100 miles 
north of Bencoolen, Sumatra. 
Type. Adult male in alcohol. B.M. no. 20. 1. 15.1. 
Collected and presented by Cecil J. Brooks, Esq. 
Considering that in the Cynopturus group, so far as we 
know, there is practically no difference in size between the 
sexes, the greater bulk of the Sumatran Dyacopterus appears 
to necessitate its distinction from the Bornean form. Its 
browner colour and less blackened head also lead to the same 
conclusion. 
Mr. Brooks is to be congratulated on his discovery of this 
interesting fruit-bat, the second specimen and first male ever 
recorded of the genus Dyacopterus.
