Family 2. Nototheniid/E. 



Differ from the Bovichthyida3 in the toothless palate, the united gill-membranes, 

 and in having all 3 radials on the hypocoracoid (fig. 3, 2 and 3). Vertebrae 45-56 

 (16-20 -f- 25-35). 



In the typical genera the skeleton is well ossified, and the rather strong ribs and 

 epipleurals are inserted on well-developed parapophyses, or only the first one or two 

 ai-e sessile. In Pleuragramma the skeleton is weak, with the bones thin and papery.
