2. TRI^NOPS. 125 



aTikle ; feet long, slender ; toes equal in length, armed with long and 

 strong claws ; tail included in the interf emoral membran e, the 

 extreme tip alone free. 



On the upper surface the fur is very pale huff, almost white, with 

 light sepia tips, darkest on the back of the neck, along the anterior 

 margin of the scapulae, and between the shoulders ; towards the root 

 of the taU of a yellowish tinge throughout ; beneath, wholly very pale 

 bufi or dirty yellowish white, cutaneous system of the same colour. 

 The fur is everywhere long and dense ; in front it covers the posterior 

 surface of the hiader nose-leaf, exceeding in length the height of the 

 trident-shaped crest. Behind, the fur of the back extends on to the 

 base of the interfemoral membrane nearly as far as the end of the 

 second caudal vertebra ; on the wing-membrane its extent is very 

 limited; beneath, the wing-membrane is covered with hair nearly 

 as far as a line drawn from the middle of the humerus to the middle 

 of the femur, but the humerus and femur are completely naked 

 beyond the body ; the distribution of fur on the under surface of the 

 interfemoral membrane is similar to that above. 



The anterior upper premolar is minute with a flattened crown, 

 and is placed outside the line of teeth ; the upper and lower inci- 

 sors are bilobed ; the upper canines have large cusps at their bases 

 posteriorly.

2. Triaeuops afer. 

 Triffinops afer, Peters, MB. Akad. Berl. 1876, p. 913, fig. 2 (head). 



Eesembles T.persiaus closely in general structure and in size, but 

 distinguished by the form of the inner margin of the ear-conch and 

 of the lanceolate process in the centre of the nose-leaf, also by the 

 darker colour of the fur. In T. persiciis the inner margin of the 

 ear-conch is abruptly emarginate about the middle, and the angle 

 thus formed is obtuse ; in this species the inner margin is also 

 abruptly emarginate, but the angle formed at the commencement of 

 the emargination is deeply right-angled ; the central lanceolate 

 process of the nose-leaf, which in T. persicus is unicuspidate and 

 very acutely pointed, in T. afer is bifid, and terminates in two jjro- 

 jections, whereof the anterior is shorter. 



The terminal phalanx of the fourth finger develops a bony process 

 similar to that in T. p>ersicus.
