Fig. 29. Outlines of occipital processes of various individuals of Notarius parmocassis (Cuvier 

 and Valenciennes). Total length of specimens the processes of which are figured in order from left to 

 right: 376 mm.; 418 mm.; 480 mm.; 435 mm.; 375 mm.; 232 mm. 



Several specimens, 232-480 mm. Georgetown market. (C. M. Cat. No.

This species differs from grandicassis in having the occipital process separated 

 from the occiput by a broader constriction and the process more elongate-ovate. 



Vomerine teeth are present in the adult. No patches of teeth are found back 

 of the two triangular palatine patches.
