materially larger, and the ears are also larger. Fur soft and 

 fine, the general mass of" the hairs about 8 mm. in length on 

 the back, but with other longer hairs, attaining 13-14 mm., 

 intermixed with them. Colour above about as in S. zenkeri, 

 the hairs brown at base, then greyish white, with pale russet- 

 brown tips. Head with the brown and white markings more 

 strongly defined than in that animal, the ground-colour a 

 little darker, the white patches prominent, present between 

 the eyes, at the posterior angle of the eyes, at the anterior 

 bases of the ears, and along the upper lips. In all other 

 respects, in colour, degree of hairiness, and the marked 

 reticulation of the wings, C. argynnis is so like S. Zenker i as 

 not to need detailed description. 



At least this is the case so far as dried specimens are 

 concerned, but Mr. Bates states that in the fresh state the 

 wings, ears, eyelids, and muzzle were (i bright orange colour/' 

 and some traces of yellow are still present on such parts of 

 the type as have been protected from light. Possibly the 

 same may be the case with Scotonycteris, but we have no 

 evidence on the subject.

 taken in the flesh) : — 



Forearm 60 mm.

ISkull : greatest length 28*3 ; basal length 25 ; zygomatic 

 breadth 20 ; interorbital breadth 5*2; tip to tip of postorbital 

 processes 11*7 ; brain-case, breadth 13*6; palatal length 10'6; 

 post-palatal length 14'4 ; front of canine to back of m l 9'2.
