occasionally taken in the lower part of the Chesapeake Bay, and Prof. 
Baird obtained specimens about three inches long in August among the 
eel-grass on Tuckahoe River, in New Jersey. Stragglers have been taken 
at New York, and even as far north as Wood’s Hall, Mass. They are 
occasionally brought to the New York market, where they are highly 
esteemed. Gill, writing in 1856, said: ‘‘I saw a single specimen of this 
species in Fulton market last year, which remained exposed on the stall

the Long Island coast, near Flatlands. He speaks of its excellence as a 
fish for boiling, comparing it to the Sheepshead. By the fishermen of St.

allied species, Centropomus robaleto, is the ‘‘Constantine’’ or ‘* Robaleto” 
of the Mazatlan fishermen. 
The Centropomus is a perch-like fish, and is not unlike Sfzostedium in 
appearance and structure. Its habits are very like those of its fresh-
