PONTINUS, Poey. 



ronthius, PoEY, Mem. Hist. Nat. Cuba, 11, 1858, 172. 



Svbastoplus, Gill, Proc. Acad. Nat. Sci. PhiU., 18G3, 208.— Jordan, Rep. U. S. F. C, 1885 (1889), 679. 



Scorpsenids similar in form and general structure to Helicolenus, but having the pec- 

 toral rays all simple and their tips only free; having six to nine rays in the anal; the 

 suborbital keel composed of three distinct, dift'ereutiated, Hat, knife-like spines, and two 

 prominent retrorse spines on each suborbital. 



A YOUNG PONTINUS. 



The type of this genus is Poiitinus cantor (Poey), which, with the allied species, P. 

 poUux, described at the ^ame time, is probably a shoalwater ftn-m, pccnliar to the West 

 Indian fauna. The genus is apparently precisely equivalent to Gill's Schastoplus, described 

 by him in 1803, of which Sebastes Kuhlii was designated as the type.
