Leucopolius, Bonaparte . 1 
AEGIALITIS NIVOSA, Gassin. 
Ch. —Small, belonging; to the same group and somewhat resembling Charadrius azarae and falklandicus of authors. Bill 
straight, pointed, rather narrow ; wing moderate, first quill longest ; tail short ; legs moderate, rather slender. 
Front, line over the eye, and entire under parts white ; subfrontal band black ; head above light brownish ashy, with a tinge of 
reddish yellow ; upper parts of body and wings light ashy brown, darker on the rump. Quills brownish black, with their shafts 
white ; some of the shorter primaries irregularly marked with white on their outer webs ; secondaries tipped with white, and 
some of the longer secondaries almost entirely white ; middle tail feathers brown, outer white ; bill dark ; legs light. A dark 
spot on each side of the breast, probably indicating a band across the breast in more mature plumage than the present specimen. 
Total length about inches ; wing, 3J ; tail, 1|. 
Hab. —Presidio (near San Francisco) California. (Lieut. W. P. Trowbridge.) 
A single specimen of the bird now described is in Lieut. Trowbridge’s collection from the 
coast of the Pacific, and appears to be a species not previously noticed by naturalists. It is of 
the same group subgenerically as C. azarae of South America, but is quite distinct from that 
or any other which has come under our notice. It is the first representative of the group to 
which it belongs yet discovered in the United States.
