Gen, Sebastodes.— With the characters of the typical Sebastes,except that the top of the head is always smooth, the spinous ridgesbeing so little developed as to be barely discernible, the orbits notelevated. In what manner the species of other waters should be distributedunder this division I do not purpose at present to specify. Themeans of reference to original authorities are here, unfortunately, sosmall as to make the attempt useless. The Californian species,however, hitherto discovered may be arranged and designated thus:— 1. Sebastes nigrocinctus, Ayres, Proc. Cal. Acad. Nat. p. 25, and p. 217, fig. Q7. Sebastichthys nigrocinctus, Gill, Proc, Phil. Acad. Nat. Sci. 1862,p. 278. This is more strongly marked in the generic features than anyother of our species. The spines of the top of the head are veryprominent; the nasal spines strong, while nearly continuous fromthem are a pair of slender interorbital ridges ; the supraorbital crest. sometimes a single ridge, and sometimes a series of spines or tuber-cles ; posterior to these a row of blunt tubercles, extending acrossthe top of the head, varying in number from two to five or six;posterior to these the occipital ridges, very high, and commonly notterminating in a spine. The posterior suborbital terminates in adistinct spine. The preopercular spines are less prominent than inmost of the species, consisting of two, or at most three, on the pos-terior border, with one or two rounded but not spinous projections 334 Zoological Society :— beneath. The humeral suprascapular and two opercular spines areof moderate development. The spinous and soft dorsals are aboutequal in height, the spinous rays quite stout. The second anal spineis higher and stronger than the third. The colours in this species are entirely characteristic, and verystrongly marked. The fish is of a plain reddish yellow, crossed
