disk of IV in talamancae, but in latinasus they are the same 

 size. 



There is marked sexual dimorphism in talamancae. The 

 throat of the male is black and the third finger of the male is 

 so swollen that the disk is no larger than the rest of the finger. 

 These characters are not apparent in latinasus. 



Finally, while latinasus has the normal tadpole of the genus, 

 with labial teeth 2/3, as described for suhpunctatus, sylvatica, 

 and ti'initatis, the tadpole of talamancae has no labial teeth, 

 but a highly developed labial disk, like that of Microhyla 

 achatinu and Megalophrys montana and entirely different 

 from anything hitherto described from America. 



Phyllohates kingshuryi Boulenger, a large species with gray- 

 ish mottling on throat and chest, seems to occur east of the 

 Canal Zone. Specimens considered to be this form have been 

 seen from Rio Calobre about south of the Gulf of San Bias 

 (U. S. N. M., 53737-8), and from Cana (U. S. N. M., 50177, 

 50197-50200). 



In the cloud forest above the Chiriqui lagoon, on the slopes 

 of Chiriqui and Horqueta, and in the drier forest down as far 

 as Boquete lives another species allied to talamancae and hav- 

 ing the same sort of tadpole. It may be called 



Phyllohates nubicola, new species 



Diagnosis: Closely related to P. talamancae (Cope) from 

 which it may be distinguished by the following characters : 

 the black line on the dorsal .surface of the thigh is not hooked, 

 the thigh is red in life and the belly yellow, the tip of toe 

 V reaches past penultimate joint of toe III, two phalanges of 

 toe IV reach beyond the tip of toe V, the tip of toe I reaches 

 the penultimate joint of toe II. 



From P. latinasus it may be distinguished by the white line 

 from the groin reaching the eye, and by the disk of toe V being 

 half the size of the disk of toe IV, as well as by the black 

 throat and swollen third finger of the male, in M'hich charac- 

 ters it agrees with talamancae.
