278 AMERICAN FISHES. 
they are usually arrayed in net-work, or in such manner as to produce a 
‘marbled ’’ effect.* It has been called the ‘‘ Hump-back Pickerel,’’ and is 
of little value for food. 
The common names of this group of fishes offer an opportunity for much 
curious research. ‘The oldest name in literature is the Latin ‘ Lucius,” 
by which it was doubtless known to the gourmets of classic times, 
which was mentioned by the poet Ausonius, in the fourth century,+ and 
which lingered in the old French ‘‘Lus’’ and the names ‘ Luccio’’ or 
“‘Luggo’’ by which Italians still know the species. at 
Although it is customarily stated that the Pike was unknown to the 
ancient Greeks, I see no reason to doubt that this is the fish which Athen- 
wus, sixteen centuries ago, called Lycus, just as the Germans of to-day 
name it in familiar phrases the ‘‘ Wasserwolf’’ (Water Wolf). Another 
vestige of this name, is the English ‘‘ Luce,’’ commonly applied to large 
individuals in the days of Chaucer,{ and not unfamiliar in later days, 
because of the extensive use of the fishes under this name as one of the 
symbols of heraldry. Shakespeare has immortalized the arms as well as 
the name of the name of the country squire, whom he hated, in his 
allusion to the escutcheon of the Lucys, and the blood-thirsty Sir Lucius 
O’ Trigger in Sheridan’s ‘‘ Rivals,’’ doubtless owed his prznomen to the 
savage Esox. 
The name Pike, the philologist says, has been given to this fish, either 
from the likeness of its nose to a pike or spear, or because it moves itself

I depart from my usual custom, and present a key, in which some technical terms are used. This table is 
based upon Jordan’s diagnosis.
