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. Cotumiculus 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 lower 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 white 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 brownish- 

 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,
