nifiMis, on tlic Lack, davkev, almost black, on the head. Below 

 dull uiiii'onn p,rry, ])aler tliaii the back. 



Ground-colour of ears and membranes black, but on all the 

 fin<j:er-joints and on the membranes between them there are 

 numerous prominent yellow spots, forming a most obvious 

 and peculiar characteristic. As already noted, there is also 

 one of these spots on the anterior margin of each ear. 



Skull with the usual short muzzle of Ci/nopterua and 

 showing no tendency towards that of Xantharpyia. 



Teeth different in number to those of any other known 

 species, viz. :— I. f, C. \, P. I, M. ^x 2 = 30. 



Inner upper incisors nearly twice the length of the outer 

 ones; canines short, not much exceeding in length the middle 

 premolar. Anterior premolar and last molar both very 

 minute, about equal in section to one of the inner upper 

 incisors. Lower anterior premolar and posterior molar also 

 very small, equal to each other, and about two or three times 

 the size of the corresponding upper teeth. 



Dimensions of the tyjie (an adult male in spirit) : — 



Forearm 41 millim. 



Head and body Qb ; ear from notch 10 ; thumb (including 

 claw) 16*6 ; index finger (including claw) 31*5 ; metacarpal 

 of third finger 30 ; lower leg 14'5 ; calcar 4*4 ; depth of 

 interfemoral in centre 4. 



Skull : basal length 20*6 ; greatest length 23 ; greatest 

 breadth 15"7; interorbital breadth 5"2 ; palate length 11*9. 



Hah. Sarawak. Coll. A. Everett, June 1892. 



This most remarkable little species, of which six specimens 

 were obtained, is distinguished from all others by its extra 

 posterior molars, two instead of four lower incisors, and by 

 the characteristic spotting of the wing-membranes and joints. 

 In other respects, in colour, size, and the absence of a tail, 

 it appears to agree with C. melanocephalus, Temm., which 

 Dobson erroneously placed with the tailed species of the 

 genus, and to which it is probably most nearly allied. That 

 species, a native of Java, is as yet only represented by the 

 typical examples in the Leyden ]\Iuseum, and these are so 

 faded that little stress can be laid on their coloration. At 

 the same time Dr. Jentink has kindly reexamined them at 

 my request, and informs me that all the three skulls in that 

 museum have four lower incisors as usual, that none of them 

 have any trace of the minute extra molars in the u])per jaw, 

 and that, so far as he can toll, the wing-membranes are quite 

 without the white spots present in C. maculatus.
