feet. It is about the size and resembles in appearance (if we except the pro¬ 
boscis), a small Sun Fish. 
The well known Porgy ( Ephippus faber ) belongs to the same order, 
although its family is different and lacks the peculiarity of the fly-shooter. 
The Coral Fish, or Wandering Chaetodon, is a carnivorous fish; is dis¬ 
tinguished alike by its shape, habits and color. It is circular, or disc-like; its 
color is a yellowish-gold, marked by purplish-brown lines. These lines are greatly 
varied in form and direction so as to suggest the branching of the coral. 
The Surgeon Fish ( Teuthidae , Acanthurus chirurgus ) is a small fish, but 
its tail, armed as it is with a curved 
spine, or with stout prickles, inflicts the 
most painful wounds upon its incautious 
captor, doubtless intending to “ operate 
upon him for cataract,” that in the future 
his sight may be better. 
The Eagle Fish (Scz&na aquila ) 
abounds in European seas, especially 
the Mediterranean, a locality whose promi¬ 
nence in history is not confined to 
politics, state-craft, and war, but is equally 
pronounced in the study of animal life. 
It is about five feet long, swims in schools, 
surgeon fish. and being held in the greatest esteem 
by those who live to eat, is an object 
of interest to the fisherman. It makes a noise as it swims, and possibly this 
has led to its name o.n account of a forced resemblance to the scream of the 
eagle; or, it may be that its rapacious habits are responsible for the name. 
The sound emitted by the eagle-fish is, it must be confessed, more like a 
porcupine grunt than like the scream of the king of birds. 
Other species—the Sea Chub, the Weak Fish, the Louisiana Red Fish, 
the Black Sheep’s 
Head, of Lake Huron, 
are among the most 
inviting articles of food, 
and render the obser¬ 
vance of Lent anything 
but the abstinence which 
has given meaning to 
the phrase, “ lenten fare.” 
The Drum Fish, 
or Drummer Fish, is eagle fish. 
represented by a salt¬ 
water species and by a fresh-water species. 
The salt-water Drum ( Pogonias chromis) wears its beard upon its neck, 
as one might describe the barbels of the lower jaw. The interior dorsal fin, 
placed about a third of the distance from head to tail, is like the wing of a 
butterfly, and is higher, though shorter than the posterior dorsal fin, which is 
even and extends very nearly to the caudal fin ; the caudal fin is convex. The 
ventral fins are long, but narrow; the posterior one is just beneath the back
