Observ. — The peculiar shape of the teeth is a character which will 

 readily distinguish this genus from its congeners, to which it is allied 

 by the conformation of the cephalic plates. Its lai'ge and bony scales 

 constitute another feature not less characterislic, as also the shortness 

 of its fingers and toes. 



Cyclodus gigas, Gray. 



Spec. Char. — Auricular aperture provided anteriorly with one series 

 of projecting scales. A groove over the upper labials. Prefrontal 

 plate broader than long. Vertex plate elongated, lanceolated, pos- 

 teriorly acute. Four elongated temporal shields behind the eye. 

 Yellowish-brown, transversely banded above with black. A post- 

 orbital black streak extending sometimes to the neck. Beneath 

 unicolor.
