that "he has never seen it there [South Carolina] in full plum- 

 age." It is now well known that the Knot attains the highest 

 possible plumage long before it migrates to the Arctic regions. 



This species is circumpolar during the breeding season and 

 has been found breeding at Discovery Harbor, latitude 81° 

 N., by Lieut. A. W. Greely. The Knot visits the Southern Hemi- 

 sphere in the winter and has been found in Brazil, Africa, and 

 New Zealand. 



99. Pisobia maculata (Vieill.). Pectoral Sandpiper. 



The Pectoral Sandpiper is a transient visitant and is very rare 

 during the spring migration. The only record I have is March 

 26, 1886, when I obtained a male on Sullivan's Island. In the 

 autumn, however, this species is very abundant whenever there 

 is an abundance of fresh water on the coast islands (where a spe- 

 cies of maritime grass affords protection) and the weather is 

 stormy. 



The greatest flight I ever witnessed was on September 13, 1884, 

 on Sullivan's Island, where large numbers were seen. On 

 October 12, 1885, I again saw this species on Sullivan's Is- 

 land, and obtained three specimens. 



The Pectoral Sandpiper breeds in numbers at Point Barrow, 

 Alaska, and winters as far south as Patagonia. 



The male of this species is much larger than the female. 



100. Pisobia fuscicollis (Vieill.). White-rumped Sandpiper. 

 This sandpiper is a rare transient visitant on this coast, where 



it seldom makes a lengthy stay. My earliest record is May 7,1902, 

 and the latest May 29, 1906. In 1886, it was first noted May 13, 

 and remained until May 19, while in 1888 I observed it from May 

 17th until the 22nd. The greater part of May, 1903, was stormy, 

 with much rain, and I observed from the 13th until the 25th 

 fully two dozen of these rare sandpipers. All of them were seen 

 in a cotton field, among thousands of other waders, while the 

 ground was partially covered with water, and I noticed that 

 this species invariably waded up to its belly in the water. 



I have detected this sandpiper but once in the autumn — Octo- 

 ber 17, 1904. 



Bonaparte's Sandpiper, as this species is also called, breeds on 

 the Barren Grounds of Arctic America, and in winter ranges 

 southward to the Falkland Islands.
