This species is close to Glyphis egertoni, and possibly ma- terial identified with it may belong to that species, but, following Cope, I have allowed it all to fall with the present provisionally. The crown in most of the examples is conspicuously narrow or small, and the root is mostly very wide. Several examples with extremely wide roots suggested a new species to Cope, but they.
