as follows: iris brown; bill coral-red, orange above; nail of bill bluish; 

 legs and feet pinkish- white.— (Dresser, Ibis, 18G2, 42.— Sennett, B. 

 Kio Grande, 02.) 



218. Dendrocygna fulva, (Gmel.) 



I cannot say much in regard to this species, though it is about as 

 common as the preceding in this vicinity. Like the Corn-field Duck, it 

 is a summer visitant, and both species frequent the same places. The 

 notes while flying are somewhat different. 1 know nothing definite in 

 regard to the breeding habits, but they probably do not differ much 

 from those of the other bird. Dr. Finley tells me that he did not meet 

 with it at Hidalgo. In a fresh specimen, the bill was bluish-black; legs 

 light slaty-blue.— (Dresser, Ibis, 18GG, 42.) 



219. Anas boschas, Linn. 



Xot uncommon during the winter months. — (Dresser, Ibis, 1806, 42.) 



220. Anas obscura, Gm. 



Xot common ; a few remain to breed on the marshes near the coast. — 

 (Dresser, Ibis, 1806, 42.— Sennett, B. Eio Grande, 03.) 



221. Dafila acuta, (Liun.) 



Eather plentiful. — (Dresser, Ibis, 1806, 43. — Sennett, B. Eio 

 Grande, 63. 



222. Chaulelasmus streperus, (Linn.) 



Probably the most common Duck in this vicinity during the winter. 

 My game register shows that a greater number of Gadwalls were killed 

 each winter than of any other Duck. Some remain throughout the 

 summer.— (Dresser, Ibis, 1866, 43. — Sennett, B. Eio Grande, 63.) 



223. Mareca americana, (Gm.) 



Eather common, especially in spring and autumn. — (Dresser, Ibis, 

 1866, 43.— Sennett, B: Eio Grande, 63.) 



224. Nettion caroiinensis, (Gm.) 



Common, especially during the migrations. — (Dresser, Ibis, 1866,43.) 



225. Querquedula discors, (Linn.) 



Common, arriving early in September. A few remain during the 

 winter, but the great majority go farther south, returning about the 

 middle of March.— (Dresser, Ibis, 1866, 43.) 



226. Querquedula cyanoptera, (Vieill.) 



Not rare during the migrations; more are seen in spring than in 

 autumn. 



227. Spatula clypeata, (Linn.) 



Very common in winter. I have seen several pairs on the marshes 

 during the breeding season.— (Sennett, B. Eio Grande, 03.)
