the species was found from an altitude of about 5,000 feet to 

 the summit (al)out 8.300 feet), the San Miguel specimens 

 were obtained at altitudes of 6,000 to 7,000 feet. The principal 

 habitat of this frog is evidently a large species of Bromeliaceee. 

 At 5,000 feet these epiphytes occur almost exclusively on the 

 trees and mostly above a height of five feet, but at altitudes 

 above 6,500 feet, generally speaking, they descend and above 

 7,500 feet occur on the bases of the tree trunks, on logs and 

 occasionally on the ground. The mountain top is devoid of 

 trees and the Bromeliace?e, here of large size and of course 

 growing on the ground, become the dominant plants. At 5,000 

 feet all of the specimens of this frog were obtained in the 

 epiphytes growing from 5 to 20 feet from the ground,- and 

 none were found elsewdiere. At higher elevations they were 

 found in the plants growing on the ground and on the bases 

 of the trees, and on the mountain top they were discovered in 

 the plants on the ground and in the litter about them. It will 

 be noted that on the summit, and there only, were individuals 

 found outside of the plants, but it is probable that the frogs 

 also occur to some extent on the ground in the higher parts of 

 the forest where the epiphytes are growing low down on the 

 trees. 



The breeding habits of /-/. cruentns are evidently similar 

 to those of H. uiartiniccnsis Peters in that the eggs are de- 

 posited on the leaves of plants and the metamorphosis takes 

 place in the egg, the young emerging in the adult form (see 

 plate). The acts of fertilization and egg-laying were not seen, 

 but the eggs were found in some num1)ers. They were all 

 attached to the inside surface of the leaves, and mostly but not 

 always, near the center of the plant. All of the sets were well 

 above the water held by the plant. The eggs were found in 



^ Plants higher than 20 feet on the trees were not examined.
