4 in base of skull, | diameter of orbit, moderately concave; 2 broad 

 low ridges over the large mucous canals; mesethmoid processes com- 

 pressed, thin, very little elevated; ventral process of basisphenoid rudi- 

 mentary, base of skull moderately curved. Gill rakers very large and 

 thick, comparatively few in number, 7 on vertical limb, and 14 or 15 

 movable ones and about 3 tubercles on horizontal limb of gill arch. The 

 coronal spines are an inconstant feature of this species, absent nearly as 

 often as present. In 1 specimen a slight prominence on 1 side indi- 

 cates its position. Uniform red, light below; a narrow black streak 

 along edge of spinous dorsal, the triangular incised portions of membrane 

 above it white; a similar mark between second and third anal spines; 

 fins otherwise unmarked; peritoneum black; mouth cavity white. 

 Length 12 inches. About the Santa Barbara Islands, in 233 and 267 

 fathoms. (Gilbert.) (aurora, dawn.)

The original types of this species are thus described: Head 3 in total 

 length; depth about 3. D. XIII, 13; A. Ill, 7|; lateral line 43. Body 

 short and deep ; head heavy ; mouth large, lower jaw projecting, maxillary 

 reaching to below posterior border of pupil; eye very large, orbit 1 in 

 snout, 3-g in head; interorbital space slightly depressed, 4 in head; pre- 

 orbital narrow. 3 in orbit, with an anterior simple and a posterior many- 

 pointed spine. Cranial spines low but distinct, smooth, and covered with 

 skin to their tip; the 3 ocular, the tympanic and parietal spines present; 

 opercular and preopercular spines long, simple; maxillary, mandible, pre- 

 orbital, and snout scaly ; scales of opercle rather large ; scales of sides very 

 large, with but few accessory ones. Gill rakers slender, 3 in orbit. 

 Dorsal spines all very low, the third and fourth the highest, less than an 

 orbital diameter, the soft rays 3 in head ; anal spines graduated, the sec-' 

 oud not much more than length of soft rays. Body scarlet, shading into 

 madder brown or blackish red above lateral line; fins vermilion, the first 

 dorsal with its membranes narrowly black-edged ; all other fins more or 

 less black on posterior half, the caudal most so ; head vermilion, tinged 

 with black; inside of mouth and gill cavity almost wholly black; upper 

 posterior portion of gill membranes black; a black bar above opercle; 

 peritoneum black. Length about 22 inches. Point Loma, California.
