NEW OR LITTLE KNOWN FISHES. 243 



rim of orbit across preopercle and lower end of sub- 

 opercle; a dark blotch on opercle; a blackish area in 

 front of dorsal and under first and second spines, extend- 

 ing with interruptions to axils of pectorals and on to the 

 base of the fin, and downward and backward in a narrow 

 broken band toward vent; another band from below 6th 

 and 7th dorsal spines downward and backward nearly to 

 origin of anal; a third short one from below 9th and 10th 

 spines to lateral line ; a broad one under soft dorsal ex- 

 tending below lateral line, and another across peduncle; 

 all these dark areas extend up on the dorsal fin; their 

 outlines are not sharply defined, and they as well as the 

 lighter areas of the body are mottled with scattered, much 

 darker spots; the lighter areas were in the fresh state a 

 dull brick red, becoming lighter below. Dorsal mem- 

 brane blackish between 1st and 3d, and between 5th and 

 nth spines. Soft dorsal spotted with blackish anteriorly : 

 membrane of caudal dusky, the dark much broken into 

 spots; anal and ventrals dusky. Pectorals with a broad, 

 transverse, dark, spotted band near base, and a trans- 

 verse dusky area with darker spots on distal half. Fins 

 in life more or less tinged with the reddish color. Peri- 

 toneum white. Types, three specimens 7^, 8% and S l / 2 

 inches long (No. 3893, L. S. Jr. Univ.), from Monterey, 

 found in San Francisco market. Many others have been 

 since obtained from Monterey, where it is common. The 

 species is an ally of Sebastodes carnatus and Sebastvdes 

 chrysomelas. It had been previously confounded with the 

 young of Sebastodes carnatus. It seems to reach a smaller 

 size than any of the related forms. 



This species is named from Prof. Charles Henry Gil- 

 bert, of Leland Stanford Junior University.
