Hylodes longirostris Boulenger/'' differs in the long snout containing; 

 the eye-diameter about If in its length, and the coloration. 

 (Named for Pagma Forest, where the type was secured.) 



BNGYSTOMATID^. 

 Phryniscus laevis Gunther. 



Twenty from the mountains above Chimbo, at an elevation of 

 10,000 to 10,800 feet, in April, 1911. 



Nine from Hacienda Gorzon to foot of Mount Pichincha, on May 

 16,1911. 



One from Quito, on June 4, 1911. This and the above collected 

 by S. N. Rhoads. 



One obtained by Dr. M. Meitzner, from Huigra to Rio Chiguancay. 



Mr. Rhoads says these frogs were found in the open pastures along 

 the mountain side. They appeared to crawl or walk, and when one 

 endeavored to grasp or try to catch them, they weakly tried to hop. 

 The sexes were noticeably different, and the males were always much 

 smaller. As this was the spawning season, they were usually found 

 copulating. The males clasp the females very tightly, mount from 

 above, and their grasp is axillary. Sometimes another male would 

 grasp a male already in coitus. All found were in wet or damp 

 places, extremely abundant, and appeared usually oblivious to 

 danger. When handled they made a weak squeak. Variation in 

 color was very great, and on the lower surface of the body varied 

 from dark orange, brick-red to lighter or sometimes to a gamboge 

 tint. Upper surface of body usually not variable, mostly olive- 

 brown. None of the larger animals, as hawks, opossums, rats or 

 foxes seemed to prey on them. Their only enemy appeared to be 

 an ant thrush {Grallaria monticoJa), and it did feed on them.

 Chiguancay and Chanchan Rivers, taken in March, 1911. Color
