FROGS OF COLOMBIA — COCHRAN AND GOIN 73 



and Valle. The species probably occurs also in other parts of the 

 country. 



Some of the frogs from Leticia have a much paler ground color 

 than the described specimen, so that the dark leg bands stand out 

 more clearly, and a scattering of large dark spots on the sacral region 

 and center of back can be seen. The large old specimen from Villavi- 

 cencio (MLS 266) has the toe webs nearly uniform brown in color, 

 while the dark spots are concentrated along the sides and in the groin. 



The largest specimen measured (MLS 266, from Villa vicencio, 

 Meta) has a total length of 110 millimeters. In a tadpole measuring 

 28 millimeters in head and body length (AMNH 22600 from Sonsdn, 

 south of Medellin, Antioquia). the arms and legs had appeared and 

 the tail was reduced to 15 millimeters in length. In AMNH 39276 

 (from Envigado, Antioquia), measuring 40 millimeters, the arms, 

 legs, ear, and mouth were completely developed, while a very slight 

 tail vestige remained. In AMNH 39275 (42 millimeters, and also 

 from Envigado), the tadpole is still in metamorphosis, with neither 

 the adult tympanum nor mouth formed. 



As for other wide-ranging species, a careful study of all available 

 material of Rana palmipes from throughout its range is needed to 

 discover the amount of geographical variation. As such a study cannot 

 be attempted in this paper, only Colombian examples are listed here.
