the hindmost resembles No. 48939 of L. anceps, while

Liodon haumuriensis, Hector \ 



Imperfectly known. There are fifteen teeth in the upper jaw,

The following specimens are from the Cretaceous of Amuri Bluff,

R. 812. Fragments of skull. 



R. 813. Portions of mandible with teeth. 



R. 814. Imperfect vertebrae.

Liodon perlatus, Cope 2 . 



Of large size, with the anterior trunk vertebras much depressed, 

 and the teeth but slightly compressed. 



Apparently closely allied to L. dyspelor, Cope 3 , of New Mexico. 

 Cope separates the present form from the imperfectly known Liodon 

 brumbyi (Gibbes 4 ) of Alabama ; but as the trunk vertebras of that
