Instead of scales, the skin is studded all over with minute prickles, extending somewhat 
along the rays of the fins. 
The ground color is of a uniform rusty red, with a black hand through the middle region of 
the orbit, and directed obliquely downwards and backwards across the cheeks. The anterior

Family SCORE AENEDAE, Swains. 
The body is always covered with scales ctenoid in structure, and the dorsal fin unique, the 
spinous portion combining closely with the soft portion. The head is large, and more or less 
spinous, a trait most develoyed in cottoids; and, the genus Scorpaena, in addition to spines, 
exhibits membranous or cutaneous flaps or appendages, which give to it a very unprepossessing 
appearance. Similar, though less numerous appendages, we have observed in some heterol^nids 
and cottoids also. Another feature, peculiar to the genus Sebastes, it is tyue, resul.., .rom the 
fact that small scales extend all over the head to its upper surface, as well as the sides, to the 
very tip of the snout and along the jaws. There are seven branchial rays in all, and the branchial 
apertures or gill openings, whichever called, are continuous under the throat. The gills them¬ 
selves are three and a half on either side, the fourth having but one branchial comb developed. 
The last branchial split, consequently, does not exist. 
The fishes of this family are all marine. 
The species^ of Sebastes are marketable fishes, and are sold at San Francisco under the 
names of rock-fish and rock-cod. Some of them reach a considerable size, weighing from one 
to four pounds, and quite esteemed as an article of food, hence one of the great resources on the 
coast of California.

flaps. Mouth large, though moderately cleft; jaws sub-equal; lower one slightly projecting. Teeth upon the premax-

rays seven on either side. One dorsal fin: anterior portion spinous. Caudal fin rounded off posteriorly. Ventrals inserted 
somewhat behind the base of the pectorals. Body covered with pectinated scales. Lateral line concurrent with the
