tending from the eye downward halfway from the angle of mouth to 

 the axilla. This line is rendered more conspicuous by the black spots 

 bordering it above and below. The belly is mottled in two shades of 

 gray. There is a white thread-like line extending the length of the 

 lower surface with a branch going off to each arm. The sides, groin, 

 rear of femur and sides of legs are heavily marked with inky spots. 

 There is a cinnamon, fawn or orange tinge in the groin, on the femur 

 and upper arm. The eyes are prominent and bead-like. 



Structure: Toes and fingers slender, feet with very short webs; 

 tubercles under joints of toes prominent; inner and outer sole tuber- 

 cles large, each with a cutting edge; legs short; one of the striking 

 things is the short 5th toe in contrast with the 3rd toe. 



Voice: Not on record. 



Breeding: They breed from March to September in periods of 

 heavy rain. The eggs are not on record. The tadpole is small, 1 1/12- 

 1 1/5 inches (27-30 mm.), wide and flat like Gastrophryne. It has 

 a broad mid-dorsal band of dark grayish olive, with the edges scalloped 

 and, as transformation approaches, a light line bordered with black 

 from the eye to the arm. There are no teeth, no horny mandibles, 

 and no papillae. They transform from April to October, at 2/5-1/2 

 inch (10-12 mm,). 



Notes: April 22, 1925. San Benito, Texas. We found on the east 

 edge of a fine blue water-lily pond one Hypopachus just transformed. 

 It was in the wet sedges where transformed B. valliceps were hopping 

 about and Pseudacris were transforming. We found two or three 

 more, but no mature tadpoles in this pond. One had a long tail and a 

 dark dorsal band with concave scalloped edges. In a fully transformed 

 one, the tail stump looks "bronzy." The under parts are specked 

 whitish and gray. 



June 15, 1930. San Benito, Texas. Same pond. I met a riband 

 snake in the grassy edge of pond. When I stepped on it it regurgitated 

 9-10 transformed H. cuneus. This started me to working in the edges 

 of the pond where I found several transformed ones, a very few tad- 

 poles. I made another riband snake disgorge, thus securing more 

 transformation stages. One of these had the light line down the back. 

 I saw transformed H. cuneus in the grass and in cow-punched holes. 

 By turning over dried cow dungs, I found several. Under one were 6 

 specimens, under an old shoe, others, and under a clump of matted 

 cut weeds, still others, but no adults anywhere. I waited until dark 

 but heard none. 



Aug. 13, 1 93 1. Brownsville, Tex. "We had our first heavy rain of 

 the season last week, so I took advantage of the opportunity and found 

 these little toads coming out of their hiding places and going to the 

 water. I find them mostly in hollow holes in tree stumps close to 

 natural water holes." — (Letter from H. C. Blanchard).
