Abstract

The forms considered are Amia and Lepidosteus (Holostei), and Polyodon and Scaphirhynchus (Chondrostei). The cranial nerves of these forms bear very obvious relations to the degree of development of certain external sense organs. That Amia and Lepidosteus are teleost-like in their nerve relations accords with the common view of their relationships in general; Polyodon and Scaphirhynchus on the other hand show in their cranial nerves elasmobranch relations.
