clo are 2 small spines, the upper rather blunt and not conspicuous, 

 the lower longer and sharp, pointing downward and somewhat forward ; 

 on each side of occiput is a small blunt tubercle, a short dermal flap 

 1 >rli i ud each eye, and 1 sometimes present behind each occipital tubercle; 

 head naked; a band of scales along back, following dorsal outline, com-. 

 posed of 2 rows of scales for most of its length, but the posterior 5 or 6 

 scales are in a single row;, the outer and anterior edge of each scale 

 embedded, the inner and posterior edge strongly ctenoid, so the opposing 

 edges of the rows are ctenoid edges ; a single row of 37 scales along lateral 

 line, the anterior ones rougher than the others. Dorsal spines slender, 

 the fins not connected; front of anal slightly nearer tip of snout than base 

 of caudal; pectorals rather wide, reaching a little past front of soft dorsal. 

 Color olive gray, with faint irregular darker cross bars on back, the first 

 under middle of spinous dorsal, the second under first fourth of soft dorsal, 

 the third under last fourth of soft dorsals, indications of 1 on caudal 

 peduncle, and a dark streak at base of caudal fin ; sides and back mottled, 

 under parts white; yeiitrals and anal white, other fins crossed with dark 

 wavy lines. This species is closely related to Icelinus borealis, differing 

 from it in having a smaller eye, a stouter caudal peduncle, a slightly 

 wider interorbital space, shorter barbels behind eye, the barbels at occiput 

 not so constant in their presence, and in having the end of maxillary in a 

 different relation to the eye. The eye of Icelinus l)orealis is contained only 

 3 times in the length of the head in specimens of the same size as Icelinus 

 strabo and the maxillary scarcely reaches past pupil. This comparison 

 is based 011 specimens of J. borealis taken by the Albatross in the Straits of 

 Fuca and in Bristol Bay, Alaska. Puget Sound, at Port Ludlow, Wash- 

 ington, where many specimens were obtained in 1896 by Mr. Starks.

This genus is close to Artedius, with which it agrees in most respects, 

 differing in the presence of stellate scales on top of head, in the concave 

 interorbital area, the rough vertex, and in the form of the large preoper- 

 cular spine, which is bifid at tip with 1 antler-like process or hook above. 

 The mouth is smaller than in Artedius, the ventrals longer, the band of 

 scales on back more developed and the nasal spines larger. There is some- 

 times a small pore behind fourth gill arch. Shore fishes of the North
