Genus GADUS Artedi. 



Synonymy. 

 Gadus Artedi, Genera Piscium, p. 18, 1738. 



Odontogadus Gill, a. genus established on the Gadus tuxinus of Nordmann. The teeth of 

 the lower jaw are nearly biserial. The skull is much like that of Gadus, but the great frontal 

 is wider in front, and the base of the cranium more flattened and bulging outwards, &c. Five 

 upecimens of this rare species, obtained by the Hon. Geo. P. Marsh at Constantinople, are m the 

 Smithsonian Institution. Thev evidently belong to the species named Gadus euxinus by Gun- 

 tlier, on whose identification with Nordmaun's species I rely, being unacquainted with the memoir 

 of the latter author. The species, although covered by the technical character of Morrhua of 

 Cuvier, is apparently at least as nearly allied to Merlangus (vulgaris).
