480 YOUNG SEMIPALMATED PLOVER. 
have swelled our limited list of synonyms with quotations 
of all their American specimens described under this name. 
The species was first established in our “Observations on the 
Nomenclature of Wilson,” and in our “ Synopsis,” and nearly 
at the same time by Mr Caup also, on a single specimen in 
the Museum of Darmstadt, whose origin was doubtful, but 
the real one suspected. By a fortunate coincidence, Mr Caup 
and myself were led to select the same appropriate name for 
our bird, which is the less extraordinary, as being suggested 
by so material an anomaly in the characters; natural history 
conducting us in this instance to the result of one of the most 
exact sciences. 
The distinctions between the three European species of 
ring-plovers having been until lately but little understood, it 
is not to be wondered at if those inhabiting these States were 
not at once well established. North America counts also three, 
independently of the kildeer, and several others, not yet properly 
determined, inhabit other parts of the world. 
Being now regarded as a new and very distinct species, we 
have not hesitated to reproduce of its natural size a bird that 
Wilson has already represented reduced one half; but his 
figure of the adult being remarkably good, we have thought it 
best to give the young, with the subjoined description, referring 
the reader for other particulars to the accurate account of our 
predecessor. 
The young semipalmated plover is seven inches long, and four- 
teen in extent: the billis almost entirely black, being destitute 
of orange, and with no more than a little dirty yellowish flesh 
colour at the base of the under mandible. The frontlet con- 
tinued into the lora, and dilating broadly on the auriculars, is 
ofa darkish grey colour, somewhat tinged with brown: a frontal 
band obscurely continued over the eyes is white ; there is no 
sincipital black band: the top of the head is greyish brown 
down to the neck, which colour unites, and forms a single mass 
with the auriculars already described: the throat to the very 
origin of the bill, and all the under parts, are pure white, with
