Color brownish, mottled and blotched with darker. Body elliptical, 

 much compressed, moderately deep, the curvature very regular; head 

 moderate, strongly compressed, the profile little depressed above the 

 eye; eyes rather large; interorbital space broad, flattish, with several 

 series of scales. Scales on cheeks similar to those on body, rather 

 large, ctenoid, and closely imbricated. Mouth comparatively large; 

 maxillary reaching pupil, 3f in head; teeth not large, about ^l^^^, con- 

 ical, close-set, in one somewhat irregular series, or partly in two series; 

 those on colored side small. Lower pharyngeals each with a double 

 row of bluutish teeth. On the blind side the scales are more or less 

 ctenoid, sometimes smooth ; those on the cheeks weakly ctenoid ; most 

 of the opercle, the preopercle, interopercle, and subopercle on blind 

 side naked. Lateral line with a very slight arch in front, the depth of 

 which is less than one-fifth the length; accessory branch nearly as long 

 as head. Fins rather low, mostly covered with ctenoid scales. Head 4 ; 

 depth 21. D. 88; A. 65; Lat. 1. 88. L. 12 inches. Point Concepcion 

 to Puget Sound; rather common in deep water. This species bears 

 some resembrance to Hippoglossoides melanostictus.
