APHRIZA. 353 



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.

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,
