Gill-openings entirely lateral, large, each about equal in length to 

 combined ,snout and eye, and extend forward last third in length of 

 heatl. Interior not examined. 



Body scaleless, with smooth skin. Mucous system well developed 

 on head, especiallj' along preopercle ridge. L. 1. system at first 

 somewhat distinct, high, or close to back, and towards end of pectoral 

 sloping down till midway along side, when obscure to caudal base. 



Dorsals little differentiated, spines similar to simple rays, slightly 

 more pungent, both rays and spines more or less uniform and covered 

 with membrane, edge of fin entire. Dorsal origin little before 

 hind edge of preopercle. Rayed dorsal well separated behind from 

 caudal peduncle, and anal fin similar. Anal with edge notched, 

 rays graduated down to shortest anteriorly, and fin inserted a little 

 nearer snout tip than caudal base. Caudal moderately long, hind 

 edge rounded. Pectoral large, graduated to ninth ray, which 

 longest, and lower rays less graduated and thickened. Ventral 

 inserted slightly before spinous dorsal origin, extends back slightlj^ 

 more than half way to anal. Vent close before anal. 



Color when fresh largely various shades of neutral tint, with dorsal 

 and anal slightly darker. Head marked with dark blotches of neu- 

 tral tint, which somewhat obscurely defined, and radiate from eye. 

 Trunks with seven vertical broad dark bands, wider or equal to the

Only the type known. It was secured in a little slough formed 

 about the pilings of the pier, and left by the tides. The specimen 

 was alive when found, swimming actively about, though it died shortly 

 after its capture, when confined in a small vessel. 



The species falls within the subgenus Blennius Linnaeus. It is , 

 related to Blennius fucorum Valenciennes, though that species has a 

 smaller and obtuse head, its orbital cirrus bifid at tip and fringed at
