 Not procured by either of the later Expeditions. (The bird so quoted by Stevenson,. 

 p. 466, is Tringa minutilla.) 



This abundant and well-known little bird occurs throughout the 

 Missouri region, in suitable places, during the migration, as elsewhere 

 in the United States. 



A very large series of the eggs of Ereunetes shows the variations- 

 probably always observable when great numbers of any limicoline 

 wader's eggs are examined. Some of them are nearly like the Butt- 

 breasted Sandpiper's eggs described beyond, and such appears to be the 

 normal pattern. Others, however, are quite different. One variation 

 affects the ground-color, which, instead of being clay colored (very pale 

 grayish or greenish-drab), is decidedly olivaceous ; and in these eggs 

 the markings are correspondingly heavy, rather umber-brown than 

 chocolate. In another decided variety the markings, instead of being 

 bold blotching, massed at the large end, are exceedingly fine dotting, 

 uniform over the whole egg, drawn like a veil, as it were, over the 

 ground, giving the predominant complexion to the egg. The following 

 are several measurements: 1.22 by 0.84; 1.24 by 0.83; 1.20 by 0.8o. 

 The sets, complete, contain three or four eggs ; those with one or two
