of the fin almost black. Pectorals, ventrals, and anal a clear brilliant 

 light red. In alcohol there is a dark blotch on top of the caudal peduncle, 

 a couple of dark bars under the soft dorsal, usually united into one, 

 except at the base of the fin, and continued on the base of the dorsal; 

 three more or less united bands under the spinous dorsal; the bands 

 continuous across line without the interruption of a light streak as in 

 Sebastodes davilatiis; the bands under the spinous dorsal are continued 

 on the fin to the edge of the membrane, but usually leave a narrow 

 light edge. With the exception of this narrow light edge the entire 

 membrane of the spinous dorsal is sometimes dusky greenish. Two 

 broad streaks run backward from the eye, the lower one continued 

 to the base of the pectoral; a shorter narrow one just above the maxil- 

 lary; maxillary sometimes with a narrow band longitudinally. The 

 entire color is much darker than in Sebastodes davilatiis. 



The chief differences between this species and Sebastodes davilatus 

 may be here repeated. The body is deeper, and with a deeper caudal 

 peduncle, the caudal is less deeply notched; the scales are larger, the 

 anal spine stouter, the color darker, and the lateral line does not run 

 as an uninterrupted streak. 



This species was the commonest Sebastodes brought up in the dredge 

 from deep water. The longest specimen is i6 cm. in length and the 

 smallest considered in this description is 13 cm., though many smaller 

 ones were saved. The type is one of the largest specimens and is 

 deposited in the Carnegie Museum with some of the cotypes. Other 

 cotypes are preserved and are deposited in the collections of Stanford 

 University and in the American Museum of Natural History in New 

 York.

The scales on the suborbital stay together with the occipital pair 

 of flaps, which serves to distinguish the adult of this species, can not 

 always be relied upon for the young up to two and one-half inches 

 in length, as in the young the scales on the stay are often difficult to 

 detect, and the occipital flaps are sometimes aborted. The long 

 fourth lateral line serves at once to separate the species from Hexa- 

 grammos stelleri, and the concave caudal from Hexagrammos super- 

 ciliosus.
