Abstract: | Summary Based on immunological comparisons of the serum albumins ofCraspedoglossa andZachaenus with antisera to albumin of several species ofCycloramphus, it is concluded that morphological and biochemical evolutionary rates have not been comparable within the study group. Taken together, the morphological and biochemical information demonstrate that whileZachaenus is a genetic member of theCycloramphus lineage, it has attained generic status.This study was supported by NSF grant No. DEB78-23396, the Amazon Ecosystem Research Program, Smithsonian Institution, the Fluid Research Fund, Smithsonian Institution, and the Museu de Zoologia da Universidade de São Paulo.The authors gratefully acknowledge the following colleagues for their help in procuring frog samples: R.I. Crombie, M.C. Duchêne, F.I. McCullough, F.C. do Val and P.E. Vanzolini. |
