6. EMBALLONXJRA FULIGINOSA, n. s. 



* In general form this species somewhat resembles E. monticola, 

 but differs in several important particulars. It is larger ; and it has 

 the fur of a uniform sooty brown, whilst in that species it is marked 

 bicoloured, being nearly white at the root. 



In its general outline the head is very similar to that of the other 

 species of the genus ; but the snout, although small and elongated, 

 is not so pointed as in the American species, but is nevertheless 

 more so than in the African E. afra, judging from the figure given 

 by Dr. Peters. The nostrils are small and rather near together ; 

 the ears triangularly oval, longer than broad, with the outer margin 

 entire and produced at the base along the face in a line midway be- 

 tween the cleft of the mouth and the eye, and ending immediately 

 between the latter and the angle of the mouth, which are both in a 

 vertical line : all three are therefore in a vertical line. The tragus 

 has its two sides nearly parallel, but it is a little widest at the end ; 

 it curves slightly inwards, and has the end rounded as in the genus 

 Miniopteris, but is relatively broader. Thumb rather long, with 

 the two visible phalanges equal in length (the small terminal one, 

 bearing the claw, being excepted), the basal one wholly enclosed in 

 the interbrachial membrane. Wing-membranes extending to the 

 distal extremity of the tibise ; hinder limbs rather long and slender ; 

 toes half the length of the entire foot. Os calcis long ; interfemoral 

 membrane very ample, with three diverging lines from the tip of the 

 tail to its hinder margin, one on each side of these from the root 

 of the femur to the point of the os calcis, and two others, one from 

 the distal extremity of each femur to near the middle of the os calcis. 

 Transversely, this membrane has about twenty closely dotted lines. 



The fur on the crown is long and thick, and approaches rather 

 nearly the end of the nose ; the sides of the face, from the auditory 

 openings through the eyes to the upper lip, naked, or nearly so ; 

 but the upper lip is fringed with scattered short bristly hairs. The
