 There are several small species designated by the general name 

 of Teal. 



Jin. qiierquedula, L. ; La Sarcelle ordinaire, Enl. 946, and the 

 old male, ^n. circia, Frisch, 176; Naum. 47, f. 66 and 67. 

 (The Garganey Duck.) A grey ground, reticulated with black; 

 a white line round, and at the end of the eye. Sec. Common on 

 ponds, Sec. Its capsule is a pyriform enlargement. 



Mn. crecca, L. ; La petite Sarcelle; Enl. 947; Frisch, 174; Naum. 

 48, f. 68, 69; Wils. VIII, Ixx, 4; Brit. Zool. pi. 2. (The Com- 

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

 band at the corner of the eye edged with two white lines. Sec.

Mergus, Lii). 



The genus of the 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, pro- 

 perly so called; but their gizzard is less muscular, and their intes- 

 tines and cseca 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 destructive to fish. 



Three species are found in France during the winter, whose 

 variations of plumage have induced some naturalists to increase 

 the number. It is said that they breed in the North among the 

 rocks or reeds, and lay a great many eggs.
