Two neio 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 lialt" 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 numbrr — those 

 of jHyci/mene cyclotis (p. 687), though all are equally bowed, 

 instead of there being one or more straight ones anteriorly. 



Colour very like that of D. sj>adiceus, 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 spadiaua, the 

 zygomatic spread especially notable. Supraorbital forduiina 

 similarly minute. 



Canines long and strongly grooved. Posterior basal ledges 

 of all teeth ratlier less developed than in the allied species. 

 Height of premolars greater. 



Dimensions of the type (a spirit-speciraen) : — 



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 ; intertem[)oral 

 breadth (j'ij ; mastoid breadth 16; palatal length 20 5; 

 maxillary tooth-row 14'2. 



Ilai. Lebong Tandai, Upper Ke'taun River, about 100 uiiles 

 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. It* 

 browner colour and less blackened head also lead to the same 

 conclusion. 



Mr. Brooks is to be congratulated on his discovery of this 

 interesting fiuit-bat, the second specimen and first male ever 

 recorded of the genus Dyacopterus.
