Abstract

1. 1. Eighteen homologous blood proteins were compared among the 21 living species of the order Crocodilia using immunodiffusion, fingerprint and starch gel electrophoretic techniques. 2. 2. All results were concordant in aligning the true gavial (Gavialis gangeticus) and the false gavial (Tomistoma schlegelii) in a lineage that is clearly distinguishable from other living crocodilians. 3. 3. The true gavial is apparently not as phylogenetically distinct from other crocodilians as previous morphological and paleontological studies have suggested. 4. 4. These data suggest that the living members of the order Crocodilia represent a monophyletic association.
