Tuts little bird, discovered, early in May, at Engineer Can- 
tonment on the Missouri river, was first described and named 
by Say; the species was not uncommon at that season, and 
appeared to be on its passage farther north. It is more par- 
ticularly interesting, inasmuch as it enriches the fauna of the 
United States with another species of the small subgenus 
Dacnis, which may be ascertained by inspecting the bill, re- 
presented in the annexed plate. 
The orange-crowned warbler is full five inches long, and 
seven in extent. The bill is dark horn-colour, slender, straight 
entire, and tapering to an acute point; the base of the inferior 
mandible is whitish beneath ; the legs are dusky; the irides 
dark brown. The general plumage above is dull greenish 
olive, the rump and tail-coverts being bright yellowish olive. 
The head is very slightly and inconspicuously crested; the 
feathers of the crest are orange at base, constituting a spot on 
the crown, visible only when they are elevated, being tipped 
with the common colour. The whole bird beneath is dull 
olive yellow ; the inferior tail-coverts are pure yellow. The 
wings are destitute of spots or bands; the primaries are dark 
brown, olive green on the exterior margin, which is much 
paler on the outer ones; the interior margin is whitish ; the 
four outer primaries are subequal; the fifth is but very little 
shorter. The tail is even, the feathers being dark brown, 
edged with olive green on the outer, and with white on the 
inner web. 
The orange-crowned warbler resembles several species of 
indigenous and foreign warblers; and the females of others,
