about as long as head ; longest dorsal spine strongly serrated and nearly 

 equaling length of head without snout ; dorsals separated by an inter- 

 space I as long as head. Color brown; head, abdomen, and inside of 

 mouth purple, the purple areas less marked in the type specimen, which 

 is \2\ inches long. Coast of British Columbia, east of Prince of Wales 

 Island, in 1,569 fathoms, (serrw/a, a fine saw.)

D. 11,12 to 11; P. 20 to 22; V. 9 or 10; eye 4 in bc^ad. Snout short, 

 slightly exceeding diameter of eye, 3x\ in head, median ridge and nasal 

 ridges terminating each in a much projecting point, furnishing each with 

 a short rosette of radiating spines and ridges, outline between these points 

 concave; tip of snout projecting beyond premaxillaries for a distance 

 equaling that which separates the central rosette from 1 of the lateral 

 ones; infraorbital ridges inconspicuous, not reaching angle of preopercle 

 behind or bony portion in front. Mouth large, slightly oblique, with 

 extensive lateral cleft, the maxillary reaching vertical from posterior mar- 

 gin of pupil, 2j in liead, equaling distance from tip of snout to middle of 

 eye. Outer series of te(^th in premaxillary strong, succeeding from a nar- 

 row band of smaller cardiform teeth ; mandibular teeth similar to inner 

 band of upper jaw, the band becoming slightly wider at the prominent 

 symphysis. Barbel short, ^ to ^ length of snout. Eye large, the diameter 

 of orbit slightly less than interorbital width on snout. Angle of preo- 

 percle produced backward, concealing all but the extreme posterior angle 

 of interopercle, the margin appearing serrulate when divested of skin ; 

 gill membranes joined to isthmus, with a posterior free margin ; gill rakers 

 very short and heavy, 1 -j- 11. Dorsal beginning vertically above base of 

 pectorals, the second spine extremely long and slender, smooth basally, 

 the terminal half rather strongly toothed, becoming very slender toward 

 tip and terminating in a long membranaceous filament. (Inl specimen it 

 exceeds length of head, in the others it e<iuals §,that length.) Length of 

 base of first dorsal equaling i^ length of head; interspace between dorsals 

 short, I to I length of snout. Pectorals very long and slender, equaling 

 the head without the snout ; outer ventral rays very long aiul filamentous, 

 equaling length of head; vent immediately in advance of anal origin. 

 Scales rather thin, those ou back and sides with above 5 diverging ridges, 

 each of which bears a num1>er of short rigid spinules directed very 

 obliquely backward, the posterior projecting but little beyond the mar- 

 gin of the scale ; 8 or 9 scales in an oblique series between the middle of 

 first dorsal and the lateral line. Dark brown ; the fins, gill membranes, 

 lips, nostrils, and underside of snout black; anterior part of mouth and 

 lining of gill cavitj' purple ; peritoneum blackish brown. Related to C. 

 serrula, Bean, from the same region and depth, differing in the larger eye, 

 shorter mental barbel, longer snout, longer pectoral fins, shorter inter- 

 space between dorsals and the longer dorsal fin. Coast of British Colum-
