AMPHIBIANS AND REPTILES OF PANAMA— SCH MIDT 



LEPTODACTYLUS QUADRIVITTATUS Cope 

 A single specimen, U.S.N.M. No. 54177, from Gatun, collected 

 May 19, 1911, by E. A. Goldman. 



This specimen, a male, differs from descriptions in having a pro- 

 jecting snout with sharp horizontal edge. Dimorphism in this charac- 

 ter appears in a number of species of Leptodactylus. It is interpreted 

 by Noble," as a breeding season character of the male sex, used in 

 excavating the hollow in which the eggs are to be laid. A pair of 

 internal vocal sacs are present, their openings rather posteriorly 

 placed ; they are indicated externally by a fold and darker coloration.
