stations, north of Unalaska Island, in the vicinity of Unimak Pass, in 

 Bristol Bay, and south of the Alaskan Peninsula, in depths of 38 to 128 

 fathoms. A single individual was also taken with hook and line in Una- 

 laska Harbor. At one of the above stations 48 specimens were taken with 

 the beam trawl. This additional material shows that S. alutus is one of 

 the bright-red rockfish, most closely allied, perhaps, to S. miniatus. From 

 the latter it differs conspicuously in the greatly produced mandibular 

 symphysis, with the very pronounced syrnphyseal knob, as well as in other 

 respects. It is allied also to S. prorigw, but differs among other points in 

 having both postocular and tympanic spines developed. Its relations to 

 S. torevispinis, Bean, are also close. (Gilbert.) (aXovt6$, unwashen, from 

 the speckled coloration.)

2194. SEBASTODES PROEIGEB (Jordan & Gilbert). 



Head 3; depth 3. D. XIII, 13; A. Ill, 7; P. 3 in length; scales 75. 

 Body elongate, somewhat compressed, a little less slender than in Scbas- 

 todes elongatus, which this species much resembles in color and form. 

 Head rather small; mouth small, much as in S. oralis, the short, broad 

 maxillary extending to beyond the middle of the eye, the premaxillary on 

 the level of lower margin of pupil; maxillary 2 in head; lower jaw 

 strongly projecting, with a conspicuous symphyseal knob. Eye very 

 large, longer than snout; preorbital narrow. Cranial ridges very low and 

 weak; preocular, supraocular, tympanic, and occipital present; most of 

 the ridges partly covered by scales; tympanic spine minute; occipital 

 ridge not conspicuous, the spine depressed; preopercular spines sharp, 

 the second longest, the points of all directed backward; opercular spines 

 moderate. Interorbital space broad, nearly as broad as the eye, somewhat 

 regularly convex, the middle being elevated. Gill rakers very long, slen- 

 der and numerous, the longest longer than supraocular ridge, and about 

 J- the diameter of eye. Scales rather small. Dorsal fin very low, as in S. 

 ovalis, not deeply emarginate, the highest spine little more than length 

 of head; soft dorsal low, -J- as high as long, the highest ray about equal to 

 the longest spine ; caudal fin moderately forked; anal fin low, its length 

 nearly equal to the height of its longest ray ; second spine much longer 

 and stronger than third, scarcely shorter than longest ray, 2 in head; 

 pectorals rather long and narrow, the tips reaching beyond tips of ven- 

 trals to vent. Bright light red, mottled above with dusky olive green, 

 the ground color forming distinct blotches under third dorsal spine and 

 under first and last rays of soft dorsal; lateral line running in the middle 

 of a very distinct continuous red stripe, precisely as in S. elongatus; head 

 above with purplish cross shades; opercle with a dusky blotch; 2 olive 

 shades radiating from the eye; lips and tip of lower jaw blackish; iris 

 red ; caudal fin bright red, speckled with dark olive ; spinous dorsal bright 

 red, the posterior part of each membrane blackish; soft dorsal olive and 

 red; lower fins bright light red, with shades of olive yellow; peritoneum
