mud-flats arouud the AV arm-spring Lake numbers were seen running nimbly and 

 swiftly over the ground, all the while uttering a soft, rather musical, whistling note. 

 All the specimens procured were in the full breeding-plumage. 



Mr. E. W. Xelson also mentions meeting with this species on the shores of Salt 

 Lake, near the mouth of the Kiver Jordan. The birds were abundant, and he saw 

 the young — only a few days old — the 1st of August. 



The eggs of this species have an average length of 1.18 inches, and a l)readth of 

 .95. Their ground is a light fawn-colored drab, over which line dottings, lines, 

 and irregular markings of a dark bistre are equally distributed, except about the 

 smaller end, which is nearly free from any mark. These eggs were taken near San 

 Francisco by the late Mr. T. Hepburn. The eggs of uliJ. cantianus, to which this 

 species is now regarded as being very closely allied, are of a slightly more oblong 

 shape, measuring 1.25 inches in length, and .90 in breadth. They have a yellowish 

 stone-colored ground, spotted and streaked with black. 



More recent spccimcn.s of the eggs of the nirosa have a ground-color of a pale 

 grayish buff, with markings in form of small dots and zigzag pencillings of black, 

 and measure 1.25 by .90. and 1.25 by .85 inches.
