PONTINUS, Poey. 



Pontinua, Poey, Mem. Hist, Nut. Cuba. 11, 185N, 172. 



Sebastopliis, Gill, Proc. Acad. Nat, Sci. Phila., 1863, 208.— Jordan, Rep. U. S. F. C, 1885 (1889), 679. 



Scorpaenids 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, differentiated, fiat, knife-like spines, and two 

 prominent retrorse spines on each suborbital. 



A yOUNO PONTINUS. 



The type of this genus is Pontinua castor (Poey), which, with the allied species; P. 

 pollux, described at the same time, is probably a shoahvater form, peculiar to the West 

 Indian fauna. The genus is apparently precisely equivalent to QUY& Sebastoplus, described 

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