Genus Boneia} 



Boneia, Jentiuk, Notes from the Leyden Museum, 1879, p. 117. 



Characters generally those of Cynonycteris, but with two upper 

 incisors only, separated from the canines and also in front ; tail well 

 developed.

Bai's longer than the muzzle, rounded at the tips ; a prominent 

 thickened lobule at the base of the outer margin of the ear-conch : 

 nostrils deeply emarginate between, their inner margins projecting : eyes 

 equally distant from the ears and from the extremity of the muzzle ; 

 upper and lower lips deeply grooved in front. Wings from the back near 

 the spine, about one-sixth of an inch apart at their origin, and from the 

 base of the toes between the first and second metatarsal bones ; tail as 

 long as the ear and very thick, projecting two-thirds its length beyond 

 the interfemoral membrane. Face yellowish-brown ; head and upper 

 surface of neck and shoulders golden yellow ; beneath dark brown through- 

 out. Fur moderately long and dense, scarcely extending upon the mem- 

 branes ; the muzzle, ears, legs, and feet naked. 



Dentition : — inc. 



Cephalotes minor. 

 Cephalotes minor, Dobson, ' P.Z.S.' 1878, p. 875. 



Resembles G. peroni closely in general structure, but less than half 

 the size of adult specimens of that species ; the feet are much smaller 

 than in very young specimens of G. peroni, and the wing-membrane is 

 attached to the outer toe, not to the space between the toes, as in that 

 species ; it also extends further outwards, terminating opposite the second 

 joint of the next toe. 



The teeth are also slightly different ; the upper incisors are wider 

 apart ; the second upper premolar has not the prominent antero-internal 

 basal cusp observed in G. peroni ; and the first lower premolar scarcely 

 rises above the gum. 



Length: head and body 4"-5, tail 0"-6, head 1""6, ear 0"'7, foi-earm 

 3"-2, first finger l"-3, third finger (metacarp. 2"'0, 1st ph. l"-5, 2nd ph. 

 l"-9), fifth finger (metacarp. 2"-0, 1st ph. 1"-1, 2nd ph. 1"-1), tibia 1"-1, 

 calcaneum 0"-25, foot 0"-8.

' This appears to be the proper position of the genus, of which I have not yet hafl 

 an opportunity of seeing the type of the siaecies on which it is founded.
