great numbers to the small fresh water ponds in the vicinity of Fort Steilacoom, where they 

 remain during the summer and rear their young. This proverbially noisy, restless bird retains 

 all the peculiar habits on the Pacific that so distinguish it in other localities. — S. 



The kill-deer plover is a common summer resident in the interior of the Territory, arriving 

 at Puget Sound early in May, and remaining until October, raising its young during the 

 season. I have never seen this species on the coast. — C.

 Aegialtes mmlanus, Bon. List, 1838. 



AegialUii montanm, Baird and Cassin, Gen. Rep. Birds, 693. 

 Sp. Ch. — Forehead, stripe over the eye, and entire under parts, white, generally tinged with dull yellowish and ashy on the 

 breast. Another band of black in front above the white band ; back of the neck and sides dull brownish fulvous ; other 

 upper parts ashy brown, usually with many feathers edged and tipped with fulvous or rufous ; upper tail coverts lighter. 

 Quills dark brown, with their shafts white, tail brown with a wide subtermiual band of brownish black and tipped with white. 

 Shorter primaries with a white space on their outer webs, forming a patch of whit e on the wing ; under wing coverts and 

 axillary feathers pure silky white. BUI black, legs yellow. Younger, without the black band in front, and with the white 

 band tinged with dull yellow, entire upper parts with the feathers edged and tipped with dull ashy rufous. Total length, 

 about 9 inches ; wing, 6 ; tail, 3 inches. 

 Eab. — Western North America. 



I obtained a specimen of this bird, shot in a "prairie dog town" on Milk river, Nebraska, and 

 have reason to believe that it is found in southern California and New Mexico. Not observed 

 by me in Washington or Oregon. Perhaps it may be found in summer in the interior of 

 southern Oregon towards Utah. The habits of the bird I obtained in Nebraska seem somewhat 

 to resemble those of the golden plover in apparently preferring dry open ground. 



I also saw a stuffed specimen in the collection of F. Gruber, San Francisco. — S.
