 abdomen areolate. Limbs rather long, digits long, free. The wrist and heel of

The sternum of this species is a parallelogrammic cartilaginous plate, deeply 

 notched distally and not distinguished into style and disk. 



General color brown above, white below. A rose-colored vertebral band. Four 

 pale lines from orbit and one from nostril cross the upper lip. Anterior half of 

 sides finely reticulate with black, groin cherry-red. Upper posterior face of femur 

 and inner face of tibia cherry-red ; lower posterior face of femur brown punctate 

 with white. 



This beautiful species is apparently related to the H. bicumulus, Peters, 

 from Venezuela, but differs in several points. In H. cerasinus the nares are 

 terminal, many times nearer the end of the muzzle than to the orbit ; in H. 

 bicumulus less than twice as far from orbit as from snout. The tympanic disk is 

 smaller in the H. cerasinus, and the coloration entirely different. These compari- 

 sons are rendered possible by the fulness of Prof. Peters's description, and it is a 

 gratification to refer to them as models worthy of imitation in all departments of 

 biology. 



One specimen from the eastern slope of the Pico Blanco.
