tympanum small; toes slightly webbed at base; foot short; no tarsal 

 fold; parotoids sometimes extending downward to the level of the jaw. 



Voice: The vocal pouch is a round ball reaching to the tip of the 

 chin. Deflated it is a pectoral flap like B. quercicus. The call is cricket- 

 like, a low sustained trill. 



Breeding: They breed from the last of March to mid-June. "The 

 eggs are in small strings and are attached to grass and weed stems. 

 . . . The tadpoles are slightly smaller than those of B. punctatus ." 

 (Strecker, 1926, p. 10). They transform at 1/3-2/5 inch (8-1 1 mm.). 



Notes: March 28, 1925. Between San Diego and Alice, Texas, at 

 8:15 we heard in a roadside ditch our customary Pseudacris. There 

 was a strong breeze blowing along these ditches, but we heard a 

 note absolutely new to us — something like a cricket. At first I 

 thought it might possibly be Hypopachus cuneus for which I went to 

 San Diego. The instant we came to the pond and they appeared 

 light colored under the flashlight, I knew it must be Bufo debilis. It is 

 rightly named "the little green toad." In some ways, its note makes 

 me think of Fowler's toad, but is not nearly so loud or strong. The 

 call is sustained. When I first went down to the pond, I thought I 

 heard only one, but before I got the light on it to see how it croaked, 

 two of them started hopping toward the ditch. They were out of the 

 water, and are very shy forms. Their throat pouch would suggest B. 

 quercicus. In some ways, the toad and its note remind me of B. querci- 

 cus, but B. quercicus is much louder and shriller. A cricket was calling 

 nearby, and the B. debilis note is something like it. We thought 

 they had sharp noses reminding us of the narrow-mouthed toad. 



When held in hand the male gives a little bat-like click, like 

 marbles hitting together. Over in the mesquite, "devil's elbow" and 

 prickly pear, we went for two or three we heard, and came back with 

 one of them. There was a small ditch or runway there. 



By a railroad and creek bridge we heard two or three B. debilis, and 

 caught one. Pseudacris in great chorus at 9:45 also B. valliceps, and a 

 few Gastrophryne. In a shallow overflowed mesquite area, quite a 

 few B. debilis males were calling. Often times when you approach, or 

 particularly when you put light on them, they duck flat to the 

 ground. The throat vesicle when inflated is a round ball reaching 

 to the tip of the chin, quite in opposition to what we expected be- 

 cause of the pectoral flap when not inflated. . . . 



March 29. Beeville, Texas. Bufo debilis note at times is something 

 like the "clucking" one gives to make a horse travel faster.
