my cabinet, collected at Osterville, Mass., November 6, 1874. In the 
absence of sufficient material for comparison, I am unable to say whether 
this specimen represents the typical autumnal plumage or not. The 
black bill is, to say the least, a remarkable feature, and one not found in 
either the adult or young in first plumage. 
62. Coturniculus passerinus. 
First 'plumage : male. Upper surface, including sides of neck, dark 
brown, each feather edged and tipped with pale fulvous, — no chestnut 
marking. Sides of head ochraceous, spotted finely with dusky. Super- 
ciliary line pale buff. Greater and middle wing- coverts dull white. Be- 
neath dull white (in some specimens with a decided yellowish cast). 
Sides with a few dusky streaks. A broad continuous band of ovate black 
spots across the breast and jugulum, running upward in a narrowing line 
to the base of the low T er mandible. Several specimens in my cabinet, col- 
lected at Nantucket, Mass., in July, 1874. This species in the first plu- 
mage may be at once separated from C. henslowi in the corresponding stage 
by the conspicuous band of spots upon the breast, and by the darker 
and more uniform coloring of the upper parts. 
63. Ammodromus maritimus. 
First plumage. Above light olive-brown, with dusky streakings, broad- 
est upon the interscapular region, narrower and more uniformly distrib- 
uted upon the occiput and nape. A broad superciliary stripe of fulvous 
extending backward to the occiput, finely spotted with dusky upon its 
posterior half. Sides of head dull olive, with irregular patches of fulvous. 
Wing-bands of pale fulvous upon the greater and middle coverts. Beneath 
pale brownish-yellow, fading to soiled w r hite posteriorly. Sides, and a 
broad continuous band across the breast, spotted with dull brown. From- 
a specimen in my collection, taken at Bath, Long Island, September, 1872. 
64. Ammodromus caudacutus. 
First plumage : male. General coloring, both above and beneath, bright 
reddish-brown, nearly as in the superciliary stripe of the adult. Feathers 
of interscapular region streaked centrally with dark brown ; nape browmish- 
olive, unspotted. Two broad stripes of dark brown on the sides of crown. 
Wings and tail scarcely more reddish than in adult. Sides of head with 
fewer dark markings. Sides of breast somewhat thickly streaked with 
dusky ; otherwise unmarked. From a specimen in my collection, taken 
at Rye Beach, N. H., August 20, 1869. It is not a little remarkable that 
in a family whose young are nearly without exception more thickly 
streaked or spotted than their parents, — and often, indeed, conspicuously 
marked in this manner, when the parent is entirely plain, — this bird in 
first plumage should exhibit less streaking beneath than the adult, which 
has not only a continuous band of dusky markings across the breast,
