Habitat — Coast of Southern California, north to Santa Barbara. 



This species is common on the coast of Southern California, where ib 

 is a food-fish of some importance, and is usually known as the RedRon- 

 cador or Black Roncador. It reaches a length of something more than 

 a foot. 



The nominal species, called Corvina jacobi, described from young 

 specimens taken at San Diego, is doubtless identical with Corvina sa- 

 turna. The only difference indicated by Steindachner which could have 

 any serious importance is in the coloration. In the species of Hcemu- 

 lon,Anisotremus, and other analogous groups the young often have ex- 

 actly the coloration assigned to C. jacobi, while the adult may be very 

 differently marked. We have not seen the very young of saturna, but 

 have no doubt that it passes through the " jacobi' 7 coloration in the 

 course of its development. 



69. SCIiENA FASCIATA.

 Corvina fasciata Giinther, Cat. Fish. Brit. Mus., i, 305, 1860 (copied). 

 Corvina fasciata Steiudachuer, Ichthyol. Not., vii, 21, 1868 (Chili). 



Habitat. — Pacific coast of South America. 



Our account of this species is taken from a large specimen (10839, 

 M. C. Z.) from Payta, Peru. 



The species is closely related to Scicena saturna, but it is a more ro- 

 bust fish with heavier head. The genus Bhinoseion, based on S. saturna, 

 is perfectly identical with Cheilotrsma. The name fasciata is not a 

 fortunate one, as the dark bands are not conspicuous and not perma 

 nent. 



Genus XIII.— RONCADOR. 



Roncador Jordan & Gilbert, Proc. U. S. Nat. Mus., 1880, 28 (stearnsi). 



Type : Corvina stearnsi Steindachner. 



This genus contains, so far as known, a single species, a large Seise- 

 noid of the California coast, much resembling Aplodinotus grunniens and 

 having similar teeth, except that the lower pharyngeals in Roncador are 

 separate. The Spanish name, Roncador (grunter), is one of general ap- 

 plication to these fishes, but on the California coast it is used most par- 

 ticularly for the present one. 



ANALYSIS OF SPECIES OP RONCADOR.
