APHRIZA, Aud. 
Jlphriza, Aud. Orn. Biog. V, 1839. Type, Tringa virgata, Lath. 
Ch. — Bill shorter than the head. Nostrils elongated, and rather linear. Tarsi equal to the middle toe, (which is not united 
by membrane to lateral,) transversely scutellate anteriorly. Hind toe distinct. Tail even. 
This genus, variously placed by authors, appears to be a true plover. Its hind toe and 
unarmed wing assimilate it to Squatarola, from which its short tarsi, free toes, and transverse 
scutellae in front of the tarsus readily distinguish it.

Sp. Ch. — Bill about as long as the head, rather thick at base; nostrils large, groove very distinct in the upper mandible ; 
wings long ; legs moderate ; tail rather long. Entire upper parts dark brown, lighter on the wing coverts ; head and neck with 
numerous spots and longitudinal stripes of dull white ; upper tail coverts white. Quills brownish black, white at base ; tips of 
greater coverts white ; tail with its basal half white, terminated with brownish black. Under parts white, nearly pure on the 
abdomen, tinged with ashy on th« neck and breast, and nearly every feather having a crescent or transverse stripe of brownish 
black. Bill brownish ; under mandible yellow at base ; legs dull green. 
Total length about 10 inches; wing, 7 ; tail, 3. 
Hab. — Pacific coast of North America? South America ; Sandwich Islands. 
This is a bird long known as inhabiting the islands in the Pacific; but as entitled to a place 
in the North American fauna, resting entirely on the authority of the late Dr. Townsend, who 
is represented by Mr. Audubon as having obtained it at the mouth of the Columbia river. It 
is not contained in either of the collections made by the surveying parties.
