Body moderately elongate, covered with small scales; snout short; no 

 teeth on vomer or palatines; teeth in jaws small; gill membranes united, 

 free from the isthmus; nostrils, orbital regions, and neck with dermal 

 flaps, the supraorbital flaps high. Dorsal tin long, of spines only ; pecto- 

 rals well developed, more than half length of head; ventrals well devel- 

 oped, jugular; caudal fin distinct. No air bladder or pyloric cieca. No 

 true lateral line ; a short series of large pores above pectoral. North Pa- 

 cific, representing Chirolophw of the Atlantic. This genus differs from the 

 European genus, Chirolophis, Swainson (Blenniops, Nilsson), in the absence 

 of a true lateral line. Dr. Bouleuger informs us that a true median lat- 

 eral line is developed in Chirolophis ascanii. (fipvov, moss; tirejujua, 

 crown.)

 with 2 small slender cirri, which are pale in color ; teeth subequal, small, 

 bluiitlsh, close set, in 1 row in each jaw; eyes 4 in head, near together; 

 the snout 4; supraorbital cirri 2 in head; iiiterorbital space flat; a flat 

 fringed cirrus over front of eye, these 2 joined at base, about 3 in head; a 

 small cirrus about $ length of this over posterior part of each eye, these 5 

 to 6 in head ; top of head and nape covered with series of erect cirri, the 

 longest nearly as long as eye ; about 15 minute cirri along dorsal edge of 

 lateral line, 1 on each pore. Rows of pores running around eye, under pre- 

 opercle, and along entire length of the short lateral line ; lateral series of 

 pores length of head ; gill rakers not developed. Dorsal fin beginning over 

 pectoral and running to caudal; anterior rays fringed with fleshy cirri;

 hind vent and running to caudal, to which it is joined at base; distance
