I obtained this beautiful little fish at Westport on Lake Champlain, where it appeared to 
be very abundant. It is numerous also in many streams in that vicinity. It readily takes the 
hook, and is extremely active and voracious. Its popular name in that district is the Little 
Pickerel, or Pickering, which is also applied to many other species. 
GENUS LUCIOPERCA. Gesner, Cuvier. 
Ventrals beneath the pectorals, with five soft rays. Two dorsal fins. Canine or long teeth 
mixed with smaller ones. 
This genus includes a few fresh-water fishes from the northeastern parts of Europe, from 
Asia and North America. Its name indicates the united characters of a perch and pike. In 
this State, we describe two species.
