FISHES FROM PORT LUDLOW, WASHINGTON. 559 



making the interorbital space deeply concave; width of 

 the latter about two-thirds eye; two ridges from the in- 

 ner edges of supraorbital rim run backward, and are 

 continuous with dorsal ridges of body; edge of pre- 

 opercle with three spines, the middle one the largest. 

 Two large median plates in front of ventrals on breast, a 

 row of plates along each lateral ridge of breast, a large 

 plate on each side of the union between first and second 

 median plates, and behind them a row of small plates 

 irregular in size and position, sometimes continuous and 

 interposed between median and lateral plates, and some- 

 times allowing the edges of median and lateral plates to 

 touch; 11 or 12 plates in front of dorsal; spinous dorsal 

 on 9 or 10 plates, counting to end of membrane; lateral 

 line 43. Space between dorsal ridges strongly concave, 

 the ridges coming together on caudal peduncle but not 

 uniting, continuing parallel for a short distance and then 

 becoming obsolete; upper lateral ridge ending anteriorly 

 on about the twelfth plate from head. Last rays of dorsal 

 and anal connected to the body by a membrane; space 

 between dorsals about equal to the width of a plate ; front 

 of anal midway between posterior end of maxillary and 

 base of caudal; pectoral reaching just past front of 

 spinous dorsal; vent distant an eye's diameter from base 

 of ventrals; length of caudal equal to head behind an- 

 terior ridge of pupil. 



Color blackish, with line punctulations; belly white; a 

 light streak running backward from eye to upper edge of 

 gill-opening; below this an area scarcely so wide as eye, 

 darker than the rest of body, its lower edge sharply 

 defined against the white under parts of head ; chin black ; 

 dorsals and caudal dusky; pectorals light, the rays with 

 many black spots which do not involve the membrane ; 

 ventrals and anal white.
