(LONG-SPINED SCULPIN.) 



Head 2 ; depth 5|. D. IX, 15 ; A. 14 ; V, I, 3. Body very slender, taper- 

 ing backward to the long and slender caudal peduncle. Head long and 

 narrow ; mouth moderate, the lower jaw included ; maxillary not extending 

 past eye, 2 in head. Upper preopercular spine extremely long, longer 

 than in any other species of the genus, 3 in head ; longer than eye, extend- 

 ing to or beyond tip of opercular spine, its length more than 4 times that 

 of the short spine below it; third spine turned downward: nasal spines 

 strong; a strong spine at upper posterior margin of orbit directed upward 

 and backward; occipital ridges long, low, converging behind, each ending 

 in a similar spine, sharp and directed backward; a single sharp supra- 

 scapular spine; a sharp spine on shoulder girdle at tip of the sharp 

 opercular spine ; the usual downward-directed spines on preopercle and 

 subopercle. Vertex nearly flat, bounded by low ridges. No cirri on head ; 

 skin of head smooth. Eye very large, as long as snout, 4-J in head, much 

 wider than the concave interorbital space. Skin without rough tubercles ; 

 lateral line with a series of partly concealed cartilaginous plates. Dorsal 

 fins well separated; spinous dorsal higher than soft dorsal, the spines 

 strong, the longest nearly $ head ; pectorals reaching anal ; veutrals not 

 to vent ; no trace of slit behind last gill. Olivaceous, with 4 obscure trans- 

 verse dark bars, paler below; fins barred and mottled; jaws unspotted; 

 lower side of head plain white ; belly white. Length about a foot. Atlan- 

 tic coast, from Labrador south to Virginia, common about Cape Cod; a 

 strongly marked species, easily known by its long spine and by the sharp 

 spine at the occiput, there being 18, really 20, distinct spines about the 

 head, (octodecim, eighteen; ftpinosus, spined.)

 elongate. Head long and narrow, somewhat compressed, concave between 

 the orbits, the orbital riui being elevated; lower jaw included; nasal 

 spines strong; a strong ridge above eye, with a blunt, compressed spine 

 behind it; behind this a small digitate cluster of ridges ending in low
