Habitat.—Coast of California; Tomales Bay to San Diego.. 
This large flounderis one of the common food-fishes of the Pacific coast, 
where it takes the place occupied on the Atlantic side by Paralichthys 
dentatus. It reaches a length of three feet and a weight of sixty 
pounds. From its resemblance to the halibut, it usually goes by 
the name of bastard halibut. It is readily distinguished from the At- 
lantic members of the same genus by its fewer fin-rays and by its more 
numerous gill-rakers. 
The specific name californicus must be used for this fish, the earlier 
name, maculosus, being preoccupied in the genus Paralichthys. As was 
first shown by Mr. Lockington, the small fish, called Paralichthys macu- 
losus, is simply the young of the larger fish, then called Uropsetta cal- 
ifornica. Unlike other species of the genus, Paralichthys californicus 
is almost as frequently dextral as sinistral.
