Bay, Vancouver Island; by Mr. Arthur W. Greeley in Prince William Sound, and by 

 Dr. Jordan at Sitka aud Kadiak. These specimens vary considerably in color and in 

 length of preopercular spine. 



This species is the type of a distinct genus or subgenus Oxi/cottus, nearest allied 

 to lilennicottus, but ditlering in the sharper spine of the preoi)ercle and the lateral 

 cleft of the mouth. Oxyvottus emhryum is a second species of the same group, inter- 

 mediate in form and armature between Blennicottus yloMceps aud Oxycottus acuticeps.

Differing from Nautichthys oculo/asciatus in the shorter lower tins, the lower 

 cranial ridges and the coloration. 



Head, 3 to 3;\; depth, 3^; D., VJIl, 23; A., 15; V., I, 3; P., 15; eye, 3^ in head; 

 maxillary, 2f ; lateral line with 39 spines. 



Shape of head ami body much as in i\'. ocnlofasciuUi.s. Head short, the snout

 much smaller than in N. oculofasciutus, shorter than pupil; iuterorbital si)ace narrow, 

 about 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 lower than 

 in N. oculo/asciatus, each with a coarse tubercle, lower and larger than in the other

 abruptly. I*reopercle with four blunt ])rominences, the upper often longer and more
