Genus III. Dives. 



Dives, Cassin, Pr. Ac. Sc. Phil. 1866, p. 413 : type D. smni- 

 chrasti. 



The two larger species assigned to Lampropsar by Cabanis 

 appear to me to go better near the true Quiscali, to which 

 they have both been referred by other authors. Cassin has 

 placed them in Scolecophagus under the subgeneric desig- 

 nation Dives, which I retain as a genus in its present position, 

 adding thereto the so-called Scolecophagus atroviolaceus of 

 Cuba, which agrees with them in most points of its structure.
