252. Parophrya vetulus Grd. — Sole. 



Santa Barbara to Alaska; very abundant from Monterey northward to 

 Puget Sound. It is usually one of the. smallest species, reaching a length 

 of about 14 inches and a weight of 2 or 3 pounds. Most of those seen in 

 the markets weigh about half a i)ound. It is one of the jirincipal market 

 species, and usually sells ^ell. 



253. Lepidopsetta bilineata (Ayros) Lock. — Eoclc Sole. 



Monterey to Alaska; rather common about rocky places, and abun- 

 dant in Puget Sound; considerable numbers are taken with set-lines by 

 the Chinese at Monterey. It reaches a length of 18 inches and a weight 

 of 3 to 5 jjounds. 



254. Pleuronectes stellatus Pallas. — Flounder. 



From San Luis Obispo northward; everywhere very abundant, espe- 

 cially northward and about the moutlis of rivers ; the commonest flounder 

 on the coast. It is reckoned a good food-fish when not too large. It 

 reaches a length of 2 feet and a weight of at least 10 pounds. 



255. Glyptocephalus zachirus Lockington. — Sole. 



About San Francisco and Monterey, in rather deep water; taken 

 chiefly with the sweep-nets, its mouth being too small for the hook and 

 its habitat too deep for the gill-nets. It reaches a length of 18 inches 

 and a weight of about 2 j)ounds, and is considered excellent food. 



256. Cynicoglossus pacificus (Lock.) J & G — Sole. 



Monterey to Puget Sound, in rather deep water ; generally abundant ; 

 taken chiefly in the sweep-nets. Eather common at Seattle, and often 

 brought in immense numbers from the sweep-nets to the San Francisco 

 markets. It spawns in May and June. It reaches a length of a little 

 more than a foot and a weight of 2 pounds. This species is exces- 

 sively slimy when taken out of the water. It is considered as a good 

 food-fish when large. The small ones, taken so abundantly, are little 

 valued. 



257. Hypsopsetta guttulata (Grd.) Gill. — Turbot; Diamond Flounder. 



Tomales to San Diego ; widely distributed, but not so abundant any- 

 where as most of the other species. Considerable numbers are brought 

 to the San Francisco market, but none have been noticed by us in Mon- 

 terey Bay. It reaches a length of nearly a foot and a weight of about 

 3 pounds. 



258. Pleuronichthys coenosus Grd. 



San Diego to Alaska, in deep water; not very abundant anywhere 

 south of Puget Sound, where it is quite common. It is chiefly her- 

 bivorous, like the other species of the genus, and with them spawns in 

 May to July. It reaches a length of about a foot and a weight of 2 to 

 3 i)ounds. It is rarely seen in the San Francisco markets.
