The Monterey or bastard halibut, P. californicus, reaches a 

 length of 3 feet and a weight of 50 or 60 pounds and is com- 

 mon on the California coast from Tomales Bay to Cerros Island. 

 It is one of the most common food-fishes of that coast where 

 it takes the place occupied by the summer flounder on the Atlan- 

 tic side. It lives in shallow water, the young abounding near 

 shore. It does not rank high as a food-fish, the flesh of the 

 large ones being tough and coarse, while the young are inferior 

 to most of the so-called Pacific soles. 



The summer flounder or plaice, P. dentatus, is, next to the 

 halibut, the most important of all the flatfishes on our Atlantic 

 Coast. It is abundant from Cape Cod to the Carolinas. It reaches 

 a length of nearly 3 feet and a weight of about 15 pounds. It
