 Monophyllus cubanus sp. nov. 



Type.—M\\\t male (skin and skull), No. 113,()74, United 

 States National Museum. Collected at Baracoa, eastern Cuba, 

 February 6, 1902, by William Palmer. Original number, 645. 



Characters. — Nearest the Jamaicair Monophyllus redinani, but 

 size less and skull with narrower rostrum and less deep posterior 

 portion of mandible. 



Color. — Upper parts broccoli-brown, rather darker than Ridg- 

 way's Plate III, No. 15, except in region across shoulders. Be- 

 neath ecru-drab, much tinged with dull brown. In some skins the 

 brown of the upper parts approaches prouts-brown. Ears and 

 membranes blackish. 



Skull and Teeth. — The skull resembles that of Monophyllus red- 

 viani in general appearance, but the rostrum is much more slender, 

 a character equally noticeable whether viewed from above or below. 



Zygomata similar in form to those of M. redmani, but more 

 lightly built. Mandible more slender than that of M. redmani, 

 the difference particularly noticeable in the posterior portion, where 

 depth at a point midway from coronoid process to condyle is much 

 less relatively to distance between these points than in the Jamaican 

 animal. 



Teeth as in Monophyllus redmani.
