PONTINUS, Poey. 



Ponlinus, Poey, Mem. Hist. Nat. Cuba, 11, 1858, 172. 



Sebastoplus, Gill, Proo. Acad. Nat. Sci. Phila., 1863, 208.— Jorhan', IJcp. U. S. F. C, 1885 (1889), 679. 



Scorpajnids similar in form and general structnre to Helicolenus, but having the pec- 

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

 suborbital lieel composed of three distinct, diflei-entiated, flat, knifelilce spines, and two 

 prominent retrorse spines on each suborbital. 



A YOlINCi PONTINUS. 



The type of this genus is Fontinns C((f<tor (Poey), whicli, with the allied species, P. 

 2)ollux, described at the same time, is probably a shoalwater form, peculiar to the West 

 Indian fauna. TLe genus is apparently jirecisely equivalent to Gill's Sebastoplus, described 

 by him in 1863, of which Sebastes Kuhlii was designated as tlie type.
