XXI. — Description of a new Species of Cynopterus (Pteno- 

 chirus) from Sarawak. By G. E. DOBSON, M.A., M.B., &c. 



Cynopterus (Ptenochirus) Lucasii, n. sp. 



About the size of Cynopterus brachysoma. Ears short, not 

 half the length of the head, triangular, with an obtuse tip, 

 the outer and inner margins almost equally convex above, 

 not margined with white. Face as in C. marginatus • but the 

 nostrils do not project so much, and the groove and naked 

 prominences on the upper lip are also comparatively much 

 shorter. Upper and lower lips internally fringed with papillae, 

 as in other species ; palate with five divided and five 

 undivided ridges. 



Wing-membrane from the base of the first toe on the back 

 of the foot ; calcaneum extremely short and feeble ; tail short 

 and very slender, projecting by more than half its length 

 beyond the deeply emarginated membrane. Thumb and 

 second fingers with well-developed claws. 



Fur short, on the back and shoulders dark reddish brown, 

 on the head and neck ashy at the extremities ; beneath light 

 yellowish grey. On the upper surface the fur scarcely ex- 

 tends upon the wing-membranes, and a few hairs appear upon 

 the forearm and upon the base of the interfemoral membrane; 

 beneath, some fine scattered hairs extend outwards upon the 

 wing-membrane behind the humerus and one third the length 

 of the forearm. 



Dentition — i. g, c. Yzi^pm. 3^, m. ^2=28 teeth. 



Upper incisors separated by intervals from each other and 

 also from the canines, directed vertically downwards, slender, 

 cylindrical, acutely pointed, the outer pair smaller in cross 

 section, and scarcely equalling more than half the length of 

 the inner pair ; lower incisors short, subacutely pointed, in 

 the centre of the narrow space between the outer margins of 

 the bases of the canines, and separated from each other by a 

 narrow interval ; canines moderate, without basal projections ; 

 first upper premolar small and short, in the centre of the space 

 between the canine and second premolar, with a blunt crown 

 directed slightly forwards, just rising above the gum, and not 

 equalling the cingulum of the second premolar in vertical 

 extent ; second upper premolar well developed, exceeding the 

 canine in cross section at the base ; third premolar equal to, 

 or slightly greater than, the preceding in cross section ; molar 

 about three fourths the size of the third premolar, flat-crowned,
