Smith, West American Scientist, 1885, 47 (San Diego). 
Habitat.—Coast of Southern California, north to Santa Barbara. 
This species is common on the coast of Southern California, where it 
is a food-fish of some importance, and is usually known as the Red Ron- 
cador or Black Roneador. 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 Hamu- 
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” coloration in the 
course of its development. 
69. SCIZANA FASCIATA. 
Cheilotrema fasciatum Tschudi, Faun. Peru. Ichthyol., 13, plate i, 1845 (Peru). 
Corvina fasciata Giinther, Cat. Fish. Brit. Mus., i, 305, 1860 (copied). 
Corvina fasciata Steindachner, 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 Sciena saturna, but it is a more ro- 
bust fish with heavier head. The genus Rhinoscion, based on S. saturna, 
is perfectly identical with Cheilotrema. 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 (stearns?). 
TYPE: Corvina stearnst Steindachner. 
This genus contains, so far as known, a single species, a large Sciz- 
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 OF RONCADOR. 
a. Body oblong, heavy forward; the back elevated and compressed; depth 3 in 
length; head 3} to 3}; profile long, steep, and convex, abruptly rounded at the 
snout; snout very blunt, 3} in head, about equal to the interorbital space; eye 5
