sometimes bifurcate again near the tips; pectoral of colored side exceed-

 length of that of colored side, and formed of the same number of rays, 

 first 4 simi^le, the others once forked; fourth and fifth rays longest; ven- 

 trals inserted so that their hinder axil is vertical with, or a little posterior

 slightly anteriorly, formed of a, double row of tubes, about 138 in number, 

 excluding those upon caudal ; a row of similar pores commencing at ridge 

 under upper eye, and continuing around lower eye almost to its front mar- 

 gin ; scales small, smooth, uniform over the body, and extending over the 

 head to snout, on which they are smaller; intermaxillaries and mandible 

 scaleless; scales on bliiul side similar; caudal scaly on both sides; no 

 scales on the other fins. Color uniform brownish or cinereous ; fins darker ; 

 the color formed by minute dark spots on the scales ; menilirane between 

 the fin rays closely set with dark points; blind side whitish, the ground 

 tint clouded with numerous 1)lack points. Deep waters of the Northern 

 Pacific, from San Francisco northward; found throughout I'.eriug Sea in 

 35 to 350 fathoms. This species is a thin, dry flounder, reaching a length of 

 something over a foot. It is taken in the sweep nets in deep water about 

 San Francisco. It is readily known by its long pectorjil fin. (?«-, an inten- 

 sive particle; x^ip, hand, from the long pectoral.)

Eyes and color on the left side. Body broadly ovate, strongly com- 

 pressed, i>ellucid; mouth large, oblique, the maxillary reaching to beyond 

 eye; teeth subequal, in narrow bands, or in single series; a small patch 

 of teeth on the vomer. Scales small, cycloid, imbricate, the skin without 

 bony tubercles. Lateral line strongly arched in front, without accessory 

 branch. Dorsal fin beginning on the snout, its anterior rays exserted; 

 anal fin not preceded by a spine; ventral of left side free from the anal, 

 inserted nearly on the ridge of the abdomen, its base broad, the rays well 

 separated ; pectoral and ventral fins moderate. One species. Very close 

 to the European genus Jlothits, Kafines(]ue {= Scophtlialmns, Rafinesque, = 

 Rhonibus, Cuvier, = Passer, Valaiiciennes), from which it differs in the more 

 numerous gill rakers, pellucid body, and produced dorsal rays, all charac- 

 ters of minor importance. The European Turbot (Psetfa, Swainsou), is
