pairs of small membranous and arborescent flaps, we were going to say, 

 adorning the head, but in reality contributing to render it still more repulsive to 

 an eye unitiated to scientific pursuits: the first pair is situated above the poste- 

 rior part of the orbit, whilst the second occupies the inner upper edge of anterior 

 nostril. The body is about eleven inches in total length, the head forming the 

 third of it. The eye is large and elliptical: its horizontal diameter being com- 

 prised nearly five times in the length of side of head. The posterior extremity 

 of upper maxillary reaches a vertical line which would intersect the posterior 

 rim of orbit. The second dorsal has nearly the same height as the first. The 

 caudal is sabrounded posteriorly. The tips of posterior lays of anal are even 

 with those of the second dorsal. The insertion of ventrals is under the base of 

 pectorals ; they are elongated. The pectorals are broad and very much de- 

 veloped ; their posterior extremity extending considerably beyond that of ven- 

 trals.

The scales of body are of medium size, and very small upon the occipital 

 region and the head. The opercular apparatus is naked ; scales being observed 

 upon the posterior flap of opercle only. Ground color deep reddish brown above ; 

 yellowish brown beneath. The anterior portion of back and head almost black. 

 Clouded patches of blackish, here and there, with numerous small black spots, 

 more defined on the head than on the body, and much larger on the fins. Belly 

 dull white ; throat yellowish ; inferior surface of head whitish and brownish.

11. Sebastes rosaceus, G. The general form of this species might at first 

 be suggestive of S. norvegicus, were the central rays of the first dorsal not so 

 much higher than in the latter species, giving to that fin a decided convexity. 

 The fish is rather stout than elongated, though much compressed, the depth of 

 body being about equal to the third of entire length, which is about fourteen 

 inches, and nearly equal to the length of head. The profile from the anterior 

 margin of first dorsal to the end of snout is rather depressed, whilst it tapers 

 quite rapidly from the second dorsal backwards, the peduncle of the tail being 

 rather detached from the general shape. The upper part of head exhibits but 

 two small horizontal spines, whilst the preopercle has five of them, rather stout 

 and conspicuous. The upper part of opercle has two spines, the uppermost of 

 which is the largest. The eyes are large and subcircular, reaching the upper 

 profile of head, in the length of which their horizontal diameter is comprised four 

 times, once in advance the anterior rim of orbit, and twice behind its posterior 

 rim. The mouth is broad, but the posterior extremity of upper maxillary does 

 not extend beyond a vertical line which would intersect the centre of the pupil. 

 The second dorsal is scarce higher than the first. The posterior margin of caudal 

 is slightly concave. The second spine of the anal is strong and robust ; the 

 tips of the posterior soft rays of that fin extend somewhat farther back than 

 those of the second dorsal, but do not reach the base of the rays of the caudal. 

 The insertion of ventrals is situated immediately behind the base of pectorals. 

 The pectorals are very long, their tips extending beyond that of ventrals, and 

 reaching a vertical line which would fall between the two dorsals.

The scales of the body are of medium size ; those upon the head, cheeks, oper- 

 cular pieces and throat are quite small. The course of the lateral line is parallel 

 to the outline of the back. 



The color is of a uniform reddish or crimson tint, lighter beneath. There 

 exists, on the upper part of opercle, in the region occupied by the spines above 

 alluded to, a large, elongated spot of a much deeper hue.

12. Sebastes fasciatus, G. The species which we propose here to charac- 

 terize, has more of the general aspect of a Scorpceita, than of the genus to which 

 it belongs. The body, anteriorly, is very stout and deep, the head more rounded,
