Molossops mastivus, sp. ii. 



Allied to M. cerastes, but larger. 



Size largest of the genus. Fur very close and velvety, 

 hairs of back barely over 2 mm. iu length. Structure of ears 

 and distribution of fur as in M. cerastes. General colour 

 above dark chocolate-brown, rather paler below. 



Skull like that of M. cerastes, but decidedly larger ; ridges 

 and crests much more developed, the " helmet " formed by 

 the junction of the sagittal and lambdoid crests very promi- 

 nent. Muzzle rather narrower in proportion to the length of 

 the skull, and not so markedly flattened. Brain-case also 

 less flattened above. Anteorbital ridges very heavy. Rami 

 of lower jaw very short and thick, their lower profile convex 

 from end to end.
