Crown of the head slightly raised above the face-line; muzzle 

 thick, obtuse, rounded off broadly in front, the distance between the 

 eyes considerably exceeds the distance between the eye and the end 

 of the muzzle ; ears shorter than the head, much longer than broad, 



» Dr. Peters considers (MB. Akad. Berl. 1865, p. 587) that the species de- 

 scribed under this name by Spix is identical with A. perspicillatios, as, on exam- 

 ination of the type, he found the number of molars to be the same. But Spix's 

 original description does not apply at all to A. perspidllatiis ; for the nose-leaf is 

 there described as " inferius lateraliter et antice libere pendens," whereas in that 

 species it is fastened down to, or even confluent with, the muzzle in front. (See 

 remarks at end of the description of this species.)
