curvature of the crown. Hyposaurus would seem to suggest that 

 these teeth are referable to Goniopholis, but all the known jaws of 

 that genus have the whole series of teeth conical. The vertebras re- 

 ferred to this genus by Owen are noticed among the Iguanodontidce.

Genus HYPOSAURUS, Owen 4 . 



Imperfectly known. Mandibular symphysis elongated ; anterior 

 dorsal vertebras with a haemal spine ; teeth carinated, the anterior 

 ones rounded, the posterior compressed and curved, with the enamel 

 ridged and grooved. In the teeth with rounded section the carinae 

 are placed in a plane coincident with that of the curvature of the 

 crown (as in Goniopholis), while in the compressed teeth they are in 

 a plane at right angles to that of the curvature (as in Suchosaurus). 



Cope refers the genus to the Teleosauridw, but its geological 

 horizon and the resemblance of the teeth to those of Goniopholis render 

 it more probable that it should be referred to the present family.
