PTEKOPODID^. 



and the interfemoral membrane and the legs to the ankles are covered 

 with longer hair ; on the ventral surface the fur is very short, the 

 antebrachial membrane is covered with short straight hairs, and 

 similar fur clothes the wing-membrane between the humerus and 

 femur, and extends outwards behind the elbow and forearm to the 

 carpus, becoming narrower as it passes outwards. 



Head and nape of neck greyish yellow ; fur of the back brownish 

 or greyish yellow along the middle, bright straw-yellow on the sides ; 

 anterior and posterior extremities also bright straw-yeUow above. 

 This peculiar bright yellow colour is different from that of any other 

 Bat, and at once distinguishes the species. 



Skidl and teeth similar in general characters to those of C. collaris, 

 but the skull is proportionally longer, and the brain-case less vaulted. 

 Upper incisors small, unicuspidate, separated from each other ; 

 lower incisors equal, close together, canine and second premolars in 

 both jaws separated by a wide space, in the anterior half of which 

 the fSrst premolar is placed.

Apparently similar to G. straminea in structure, but larger, and 

 differing in the colour of the fur, which closely resembles that of 

 the lighter-coloured specimens of C. collaris. 



Above, pale yellowish or greyish brown, paler on the neck ; 

 beneath simUar, but paler and dull buff-brown on the sides. The
