larly blotched with duskj^, and with line lines across the raj-^s; caudal 

 marhled, and with 2 or 3 very irregular crossbars. Pectoral dark and 

 mottled; a large light area on its upper basal portion. 



In life the color is ))lackish green or dusky red, according to the 

 color of the seaweeds about it; silvery area white. 



This species may be known from Blep.sias cirrhosus, its representa- 

 tive farther northward and eastward, by its having no naked area 

 following the lateral line, by the single naked spot behind pectoral, 

 by the prominent tentacle on superorbital rim, and by the form of the 

 spinous dorsal. 



The specimens from Iturup Island in the Kuriles that have been 

 referred to Blepslas cirrhosvs belong to this species. Specimens were 

 taken b}^ Jordan and Snyder at Hakodate and Aomori. 



The type is from Aomori: it is 19 cm. in length, and is numbered 

 7720, Ichthyological Collection, Leland Stanford Junior University 

 Museum. Others, cotypes, are numbered 50929, U.S.N.M.

 {pribilovius) . 



This genus is closely allied to JVaittic/ithys, having the same gill 

 structures and dentition, but the first dorsal is only moderately ele- 

 vated, its height being less than depth of body. There are no cirri 

 on the head, and there is no marked depression at the occiput, the base 

 of the dorsal being little raised above the nape; preopercle with four 

 obsolete spines.

Shape of head and bod\^ much as in Nautichthys oculofasdatus; head 

 short, the snout rather sharp, the anterior profile steep; nasal spines 

 prominent, a short occular cirrus, shorter than pupil; interobital space 

 narrow, al)out one-half eye, deeply concave; a blunt triangular ridge 

 above each orbit, with a deep cross furrow behind it which deepens to 

 a pit at the vertex; nuchal ridges, each with a coarse tubercle, lower 

 and larger than in the other species. From the nuchal depression, the
