The pupil is transversely oval when expanded, and subquadrangular when more 
contracted, but never vertical. It can be shut entirely. 
The palatine ridges show some odontoid roughnesses, but they are not equally 
developed in the three examples examined by me. In one specimen they are visible 
only on the outer part of the ridge of the left palatine, in another they are confined to 
the outer portions of the ridges of both palatines, and in the third the ridges are more 
conspicuous and beset with odontoids in nearly their whole length.
