Pteruphrynoides Gill, Proc. U. S. Nat. Mus., I, 1878, p. 216 {histrio). Name a 
substitute for Pterophryne, if regarded as preoccupied by an earlier name 
PteropJtrynus. 
Body short, somewhat compressed, with tumid alidomen, and cov- 
ered by smooth or slightly granular skin; mouth small, oblique; 
palate with teeth; wrist slender; ventrals elongate; color light brown,
