APHRIZA. 3D8 
was for many years classed with the Turnstones (Arenaria). Dr. Shufeldt, however, 
proved, from an examination of the skeleton, that Aphriza should be placed among the 
Plovers (cf. Journ. Morph. ii. pp. 311-340, t. 25), an arrangement which has since 
been followed. 
There is very little difference between the summer and winter plumages in this genus. 
The bill is stout, with the culmen about equal in length to the middle toe and claw, so 
that Aphriza is nearly allied to Ochthodromus, but differs from it in the presence of a 
hind toe.

Hab. Norra America, Pacific coast from Alaska to California. — Mexico, Colima

The Surf-bird, as it is called in North America, is nowhere common, and very little 
is known of its habits, which seem, however, to resemble those of the Turnstones. 
It has been found in Alaska, frequenting the mud-flats, and doubtless breeds on the 
shores of the extreme north-west of America’. In winter specimens have been 
procured on the coasts of Peru and Chile, as well as in Colima, in Western Mexico, so 
that it is probable that the species occurs along the whole of the western coast of 
Central America during migration. 
Aphriza virgata is entirely a bird of the sea-coast; the nest and eggs have not 
yet been discovered,
