Mr. Zadock Thompson, the intelligent author of the ‘‘ History of Vermont,’’ writes me, 
that he compared his description of an Amia he took at Whitehall, Lake Champlain, with 
Dekay’s A. occidentalis, Richardson’s A. ocellicauda, and Kirtland’s A. calva, and is satisfied 
‘* they all belong to one and the same species.” 
FAMILY XXII. SAURIDE. 
Body covered with scales of a stony hardness, which are extended into im-— 
bricated spines upon the first rays of all the fins. In some genera, dorsal 
finlets, each supported by a strong spine. 
GENUS I. LEPISOSTEUS, Lacep. 
Muzzle formed by the union of the intermaxillaries, maxillaries, and pala- 
tines to the vomer and the ethmoid ; jaws slightly unequal ; both jaws bristling 
over their whole interior surface with rasp-like teeth, have along their edge 
a row of long and pointed teeth. Dorsal and anal fins far back, and opposite 
one another. Their stomach is continued as far as a slender intestine, twice 
folded, having many short cceca to the pylorus ; their natatory bladder is cel- 
lular, as in Amia, and occupies the length of the abdomen. 
1. Lepisosteus osseus, Lin. 
Body elongated, fusiform. Head more than one fourth of its total length ; base of head 
less in circumference than any other section of the body anterior to the dorsal fin. Snout 
much elongated. Back and head brown or umber-colored, sides yellow, and body white ; 
several circular black spots upon the caudal, a few smaller ones upon dorsal and anal fins. 
Scales smooth. Lateral line nearly straight.
