APPENDIX C. — BIRDS. 323 



The Red-breasted Teal appears to be a common bird in Utah, 

 three having been shot in Jordan River. As the species has never 

 been described from a North American specimen, we subjoin the 

 following, taken from those brought by the expedition. 



Male. — Head, neck, anterior part of body, sides, flanks, bar 

 across the vent, rich purplish chestnut, deepest and most lustrous 

 across the breast, faintest across the vent. Upper part of the head 

 to occiput, the chin, and lower tail-coverts, dull-brownish black. 

 Lower part of breast, belly, and abdomen, (encircled by the chest- 

 nut just mentioned,) obscure brown, and faintly glossed with gray- 

 ish and chestnut. Lower wing-coverts, subscapulars, and tips of 

 primary coverts, white, showing on the latter as a conspicuous 

 white patch. Shoulders, lesser coverts, and greater part of two 

 of the longest scapulars on each side, bright blue, (darkest on the 

 latter.) Speculum, grass green. Longest scapulars with a cen- 

 tral streak of yellowish white, and variously margined and mot- 

 tled with chestnut. Back, rump, and upper tail-coverts, margined 

 with dull chestnut. Bill black, feet yellow. Bill long, narrow, 

 somewhat wider towards the tip ; nostrils oval, lamellar, rather 

 long. Tarsi short, and feet small. Outer toe, without its claw, 

 about equal to the inner with claw. Tail rather long, wedge- 

 shaped, of fourteen feathers. 



Total length (skin much stretched) 20 inches.

Female, — Similar in general pattern of colouration, the chestnut, 

 however, replaced by the mottled yellowish and brown character- 

 izing the female ducks. This pervades the whole inferior portions, 

 not excepting the tail coverts. The black of the head, and the 

 blue on the shoulders, (not on the scapulars,) are retained.
