110 BRITISH BIRDS. [ VOL: XI. 
female is like the male, but the nuchal collar is absent, and the patch 
below the eye and the pectoral band are drab. The summer plumage 
is like that of Ch. hiaticula and the sexes are alike; in some females 
the patch below the eye and the pectoral band are intermixed with 
drab feathers. 
N.B.—One male, Cozumel Island, Yucatan, January, had the 4th 
primary of each wing in quill. 
JUVENILE.—Male and female.—Similar in plumage to juvenile 
Ch. hiaticula, but the inner secondaries (not long innermost second- 
aries) as in adult Ch. semipalmatus, 7.e. drab or dusky-brown slightly 
marked with white: in Ch. hiaticula the inner secondaries are more 
or less white. 
N.B.—This species is distinguished from Ch. hiaticula im all plumages 
by the pronounced webbing between the toes. 
First Winter.—Male and female.—The body-feathers (not all the 
scapulars), not the tail-feathers in the few specimens examined, some 
innermost secondaries and coverts, some median and lesser coverts, 
but not the rest of the wings, are moulted in late autumn and early 
winter. After this moult the birds are like the adults and are only 
to be distinguished by the buff tips to the retained juvenile wing-coverts. 
First SummER.—(Not examined.) 
Three specimens (2 Florida, April 15th, g¢ Peru, May 18th, ¢ 
Coquimbo, June), were in worn first winter plumage with one or two 
new body-feathers, but no moult apparent. 
Littte RInGED PLovER (Ch. d. curonicus). 
ApvuLts.—Complete moult from July to November. From February 
to May there is a partial moult involving the body-feathers (not all 
the scapulars), occasionally the tail-feathers, some innermost secondaries 
and coverts, some median and lesser coverts (‘the median and lesser 
coverts are not always moulted), but not the rest of the wings. There 
is no difference in coloration between the winter and summer plumages, 
and the sexes are alike. N.B.—In some females the black patch on 
the ear-coverts is smaller and more or less intermixed with drab-brown 
feathers in some, black feathers more or less absent. 
JUVENILE.—Male and female.—Like the adult but has no black on. 
the forepart of the crown; the feathers of the crown, mantle and 
scapulars, instead of being almost uniform drab-brown as in the adult, 
have sandy-buff edges and subterminal sepia borders; the black 
nuchal collar is narrower and black-brown rather than black; the 
ear-coverts and the band under the eye are drab-brown or sepia, the 
feathers edged buff, not black as in the adult; the pectoral band (black 
in the adult) is drab-brown narrowing and almost incomplete towards 
the centre, the feathers tipped buff; the tail-feathers are more or less 
washed buff at tip, while the innermost secondaries and coverts and 
median and lesser coverts (drab-brown, narrowly edged white in the 
adult) have sandy-buff fringes with faint subterminal sepia borders. 
First WINTER.—The body-feathers (but not all the scapulars, and 
apparently not the feathers of the back and rump), the tail-feathers, 
innermost secondaries and coverts, some median and lesser coverts 
are moulted in autumn, but not the rest of the wings. After this moult 
the male resembles the adult, but there is no black on forepart of 
crown ; the forehead is cream-buff and the rest of the crown drab- 
brown, the feathers edged sandy; the black band below the white 
nuchal collar is in some less defined and intermixed with drab-brown 
feathers ; the lores are black tipped buff, the ear-coverts dusky brown, 
not black as in the adult ; the black pectoral band is narrower towards 
the centre than in the adult, and intermixed with drab-brown feathers,
