Amphibians and Reptiles of Santa AIarta 51 



Gastrophryne ovale ( Schneider j. — Fundacion. Only two specimens 

 observed, both under logs in low woods. 



Eleutherodactylus insignitus Ruthven.^" — Heights east of San Miguel, 

 6,000 to 7,000 feet (M. A. Carriker). Taken in bromelias on the ground 

 and in trees. 



Elentherodactylns crncntus (Peters). — San Lorenzo, 5,000 to 8,300 

 feet; heights east of San Miguel, 6,000 to 7,000 feet (M. A. Carriker). 

 Mostly found in bromelias, either on the ground or in trees. (PI. XII, 

 figs. 4, 5.) 



The habitat of this form is evidently the bromelias. In the forest at 

 5,000 feet on San Lorenzo it is to be found in numbers in the trees, the 

 bromelias at this altitude being mostly above ten feet on the trees. From 

 about 6,000 to 8.300 feet the bromelias grow lower down on the trees and 

 on the ground in open places, but the frog is still confined to them. It is 

 very abundant in the large bromelias which dominate the flora of the clear- 

 ing at 8,300 feet. 



The breeding habits have been described by Ruthven.^^ The eggs have 

 not been found elsewhere than in bromelias. The breeding season is evi- 

 dently long. Carriker collected eggs at San Miguel on April 24; and on 

 San Lorenzo, in 1913 and 1920, many sets were found as early as Jmie 9 

 and as late as July 25, the entire period during which the species was under 

 observation. The observed dates of hatching are June 15, 19, 28, 30, July 

 I, 22-25. This indicates that the eggs are laid at different times during the 

 rainy season. The number of eggs in a set is uncertain, for it has not been 

 determined whether or not the females lay all of the eggs in one group. 

 Often two or more sets may be deposited closely together, but whether by 

 the same or by different females has not been determined. Usually from 

 four to eight eggs are laid in one cluster, for when larger numbers are found 

 in one group it is possible to distinguish more than one set. The adults are 

 silent and retiring during the day, concealing themselves in the axils of 

 the leaves ; but at night they are active, the ''song'' being a rather harsh 

 "check, check." 



Eleutherodactylus carmelitae, new species^- 

 (Pl. XI. fiR". i: P1. XIT. fi.g. T.) 



Diagnosis: To be distinguished from E- sanctae-martae Ruthven by 

 the following characters : eye larger, tongue entire, tympanum less than 

 one-half the orbital diameter, nostril equidistant from eye and end of snout; 

 and from E. inegalops Ruthven by greater size and larger eye, obovate 

 tongue, larger disks (those of third finger larger than ear), smooth or finely 

 granular texture of dorsal epidermis, narrower interorbital space (much 

 narrower than upper eyelid), smaller palmar and sole tubercles, and in the 

 position of the nostril. 



Description: Tongue obovate, entire behind. Vomerine teeth in two 

 short, transverse groups close together behind the choanae. Head as broad
