Excerpt from A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus We have examined 893 preserved frogs, including the type speci mens of all included nominal taxa, 8 skeletons, 1 lot of eggs, and 3 lots of tadpoles that we refer to the genus Osteocephalus; in addi tion skulls were removed from five preserved specimens, and radiographs were made of 12 other preserved specimens. We have been fortunate in seeing living individuals of all species, except 0. Pearsom', but we have colored photographs of a living specimen of that species.

The eastern complex in general has a well-developed Outer palmar tubercle (fig. 1) in distinction to the western complex in which the outer palmar tubercle is reduced or absent (fig. Dixon and Webb (1966) imply that the outer palmar tubercle is rarely absent but is usually smaller than the first supernumerary tubercle Of the fourth finger.
