lar spine ; the interval between these snbocular bars may be silvery white ; 

 spinous dorsal often showing 2 dark bars, as in E. gloUceps; ventrals 

 plain; fins otherwise finely mottled or indistinctly barred; some or all of 

 these dark markings sometimes absent. Prince William Sound (Arthur 

 White Greeley) to Vancouver Island. Four specimens, the largest 47 mm. 

 long, from tide pools at Unalaska, are the types of the species. Three 

 additional specimens were taken in Departure Bay, Vancouver Island.

Head 4 ; depth 4. D. IX, 15 ; A. 10 ; orbit 4 in head ; snout 4 ; maxillary 

 2; highest dorsal spine 2| ; dorsal ray If; anal ray If; length of caudal 

 fin If; ventrals 1; pectorals 2| in body. Body elongate, compressed, 

 back slightly elevated, deepest under spinous dorsal; caudal peduncle 

 moderately slender. Skin without scales or prickles ; head small, taper- 

 ing rapidly forward to the rather sharp snout as viewed from above ; pro- 

 file of head straight below, acutely and evenly rounded above ; mouth 

 terminal and horizontal; maxillary reaching to the vertical from the 

 middle of pupil; lower jaw included; teeth on jaws, vomer, and palatines 

 in narrow villiform bands; process of premaxillary prominent, extending 

 slightly above nasal spines, giving the appearance of 3 spines above 

 snout; eye set high in head, the orbit as long as snout; preopercular 

 spine short, blunt, and triangular, entirely covered with the skin, edge of 

 preopercle below, entire; opercle ending in a short flap; top of head 

 with 2 rows of "mossy" cirri, running from the superior orbital margin, 

 curving over head and continuing on lateral line, they disappear on its 

 anterior third. Dorsal spine rather stout, the fin lower than soft dorsal, 

 rounded in outline; soft dorsal well separated from spinous, the front of 

 fin the highest; pectorals long, the eighth ray the longest, giving the tin 

 a point behind which reaches to the base of about the seventh dorsal ray ; 

 the same rays below the eighth swollen and posteriorly free from the 

 membrane; anal about as high as soft dorsal, the rays somewhat swollen 

 and more or less free; ventrals long, reaching about to front of anal, their 

 insertion behind base of pectoral a distance equal to the snout and eye; 

 caudal fin slightly rounded. Color variable from light green to a rich 

 maroon; traces of 5 or 6 dark crossbars on back; lower parts dusky with 

 small light spots; belly white; a dark bar from eye to side of snout, 1 

 from eye to edge of preopercle behind end of maxillary, and another from 

 eye to below preopercular spine; lips black; lower rays of pectorals 

 crossed with black and white bars which fade out above; ventrals light 

 with some dusky mottlings; dorsal dark above, light at base, no mark- 

 ings; anal with black and white bars running across the rays, caudal fin 

 mottled. In this species the preopercnlar spine is veryv short, sharp, 

 turned upward, and covered by skin. It has a more acute snout than B. 

 Ulobiwps, mouth with a lateral cleft, body more compressed, and the pre- 



inxillary process extending above nasal spines. Puget Sound to Mon-
