where it is known as the “albicore,” and comes to Northern 
waters for recuperation. Others suppose it to be the “tunny,” 
which follows ships for the crumbs from the table, and at- 
tains, off the coast of Spain and in the Mediterranean, the 
weight of a thousand pounds. I do not believe the bonetta 
to be similar to the tunny, but I know that it is called albi- 
core by some Southern fishermen. The fishes of our coast 
and estuaries which I name as belonging to the troll are sup- 
posed to be of this hemisphere, and are spine-rayed families 
ofthe mackerel tribes. Iam often surprised at the innocence 
of intelligent anglers, who do not know a cero from a Spanish 
mackerel, nor the latter from a bonetta, or a spearing from a 
smelt, and can not distinguish the great Northern pike from 
the maskinongé. 
SECTION TWELFTH. 
THE CERO, CERUS, OR SIERRA. 
It is rather a cereus matter to ascertain the names of such 
fishes as ichthyologists have left out of their catalogues; and 
as Imake no pretensions of claiming this to be a school-book, 
the angler will please scan the illustrations which I made per- 
sonally from the fishes of which these are intended to be true 
copies. 
Tue Cerro, CERus, or SIERRA. 
The cero is evidently a member of one of the mackerel 
tribes, and in esculent quality ranks between the Spanish 
mackerel and bonetta. It is a new visitant along the shores 
from Virginia to Rhode Island, but it is quite numerous in 
the West Indies. It evidently spawns in spring-time; is 
white-meated; ranges in weight from four to twelve pounds ; 
is longer in proportion to its weight than any other of his
