The snout of a new specimen of Akidnognathus parvus is described in detail
from serial sections at .5mm. intervals. Special reference is made to the structure of the septomaxillary and its possible morphological significance. It is suggested that its peculiar arrangement is relatable to a readaptation in the mode of smelling in
mammal-like Reptiles. Additional descriptions deal with new specimens assignable to
Ictidostoma hemburyi, Ictidosuchops intermedius, Ictidosuchops bauroides and Ictidosuchoides longiceps. All descriptions are accompanied by adequate figures. The new information adds little to existing views on the relationship of the families Ictidosuchidae and Scaloposauridae.
