as follows: iris brown; bill coral-red, orange above 5 nail of bill bluish;
legs and feet pinkish-white.— (Dresser, Ibis, 1862, 42.— Sennett, B.
Eio Grande, 62.)
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. I 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, 1866, 42.)
219. Anas boschas, Linn.
Not uncommon during the winter months. — (Dresser, Ibis, 1866, 42.)
220. Anas obscura, Gm.
Not common ; a few remain to breed on the marshes near the coast. — (Dresser, Ibis, 1866, 42.— Sennett, B. Eio Grande, 63.)
221. Dafila acuta, (Linn.)
Bather plentiful. — (Dresser, Ibis, 1866, 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.)
Kot 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. Rio Grande, 63.)
