ff. Body oblong, strongly compressed, semitranslucent; scales weakly ciliated; 

 about 93 pores in lateral line. Coloration, light grayish, thickly mottled 

 with darker; 4 large horizontally oblong, black ocelli, each surrounded 

 by pinkish area; 1 just behind middle of the body, below the dorsal, 1

2991. PAlJALICnTHlS ("ALIFOKIVICUS (Ayres). 



(Bastard Halibtit; Monterey Halibut.) 



Head 3| to ii; tlopth 2:j. D. 70; A. 55 : scales 100. Vortebra} 10 + 25=35. 

 Body rather long and thickish; caiKlai peduncle long; head small; eye 

 small, little wider than the broad, llattish interorbital space; maxillary 

 as long as pectoral, i length of head, reaching beyond eye; teeth slender, 

 sharp, rather long, the canines moderate. Scales small, finely ciliate, 

 each scale surrounded by narrow accessory scales; scales on blind side 

 similar; fins with ctenoid scales. Dorsal low, beginning over front of 

 upper eye just past pectoral, pointed, reaching curve of lateral line, 2J in 

 head, that of blind side shorter and rounded behind; arch of lateral line 

 SI or 4 in straight part. Gill rakers very long and slender, numerous, as 

 long as eye, about 9 + 20; lower pharyrngeals narow, with small slender 

 teeth. Anal spine small, concealed. Grayish brown, uniform, or mottled 

 with blackish and pale, the head sometimes sprinkled with black dots ; 

 young brownish, with bluish spots. Coast of California, Tomales Bay to 

 Cerros Island. This large flounder is one of the common food-fishes of the 

 Pacific coast, where it takes the place occupied on the Atlantic side by Par- 

 alivlitliys dentatus. It reaches a lengtli of 3 feet and a weight of 60 pounds. 

 From its resemblance to the halibut, it usually goes by the name of bastard 

 halil)ut. It is readily distinguished from the Atlantic members of the same 

 genus by its fewer fin rays and by its more numerous gill rakers. As was 

 first shown by Mr. Lockington, the small fish called raralichthys maciilosus, 

 is simply the young of the larger fish, then called Uropsetta caUfornica. 

 Unlike other sj)ecies of the genus, raralichthi/s californicus is almost as 

 frequently dextral as sinistral, {californicus, Californian.)
