projects beyond lower jaw; vomerine teeth in two short raised patches 

 between the inner nostrils; tympanum slightly deeper than wide; 

 tongue slightly nicked behind; fold of skin from eye over tympanum 

 almost to arm insertion; central abdomen surrounded by a circular 

 fold of skin; disks transverse. 



Voice: At a distance the call was certainly a bark, but as we 

 climbed the hill and came near, it was more of a throaty whurr. It is 

 ventriloquial to some degree, and the location of the calling frog back 

 under the ledge doubtless increases the volume of sound. 



Apr. 24, 1933. "Roy (R. D. Quillen) returned Sunday (23rd) from 

 a trip in the Frio Canyon (Texas), and the barking frogs do bark. 

 Mr. Fisher, on the ranch said that the frogs made so much barking 

 four weeks ago that he was awakened nights. We hear them every 

 evening when we sit on the front porch of the ranch house." Letter 

 Mrs. Ellen Schulz Quillen. 



Breeding: Probably they breed during any rainy period from 

 February to May. It is likely that the large eggs are laid in moist or 

 rain-filled cracks or crevices or even caves in the rocky cliffs and 

 ledges where they live. A specimen in the National Museum contains 

 about 50 eggs each measuring 1/4-5/16 inch (6-7.5 mm.) in diameter. 

 The tadpole development is probably within the egg. 



Notes: Feb. 20, 1925. Helotes, Texas. The instant I had it in 

 hand it swelled up taut, bladder-like. When I reached the store, I 

 realized I was sweating, and started to brush the sweat out of my left 

 eye; it smarted afterwards. Some cuts on my hand did also. It affected 

 the mucus of my mouth slightly. It certainly has a secretion. 



Feb. 22. In photographing male E. latrans^ it would wedge itself 

 in the cell and climb right out of the jar. When I had it in hand, it 

 bent the last joint of the two outer digits. These have expanded tips. 

 With these bent digits, it can pull readily and strongly. It must use 

 these for pulling itself along or preventing animals from pulling it out. 

 Mr. Marnock told Mr. Cope, "During the winter the adults are 

 very noisy, the rocks resounding in the evening with their dog-like 

 bark. The noise is supposed by the country people to be made by 

 lizards, especially the Gerrhonotus infernalis which occurs in the same 

 region." (Cope, 1878, p. 186). 



In G. W. Marnock's collection, Baylor University, No. 2022 has 

 a prominent transverse band across dorsum from arm insertion to 

 arm insertion. Back of it comes a broad transverse area of olive buff 

 outlined behind by two dark spots, one either side of the meson. This 

 prominent light band has a median light dorsal stripe extending for- 

 ward on meson to between the eyes. U. S. National Museum, No. 

 13,633 (G. W. Marnock, Helotes, Texas), which measures 48 mm., 

 has an indication of this median line between the eyes, and possesses 

 a quite spotted back.
