There are other species, also foreign, wliich to the bill of a Duck add 

 legs, even longer than those of a Goose; they build and perch on trees'^". 

 Some of this number have but semi-palmated feet-j-. Finally among 

 those which have no peculiar mark is the

 Naum. 48, f. 68, 69; Wils. VIII, Ixx, 4; Brit. Zool. pi. Q. (The 

 Common Teal). Finely striped with blackish; the head red; a 

 green band at the corner of the eye edged with two white lines, &c. 

 The capsule resembles a peajj. 



Mergus, Lin. 



The genus of the Harles or Mergansers comprehends those species in 

 which the bill, thinner and more cylindrical than that of the Ducks, is 

 armed along its edges with small pointed teeth resembling those of a saw 

 and directed backwards ; the tip of the upper mandible is hooked. Their 

 carriage and even plumage are those of Ducks, properly so called; but 

 their gizzard is less muscular, and their intestines and ca?ca shorter. 

 The inflation of the lower larynx in the males is enormous, and partly 

 membranous. They live on lakes and ponds, where they are very de- 

 structive to fish.
