_Casual records._--The purple sandpiper has been reported as seen at the entrance to St. George Harbor, Bermuda, and there are a few records for the south Atlantic coast and the interior, among which are: New Jersey, Delaware Bay (specimen in British Museum), Beach Haven, October 31, 1896, and one found dead at the Absecon Lighthouse; Georgia, one in the Sennett collection taken, March 5, 1874; Florida, Key Biscayne, October 29, 1857, and Gordan's Pass, November 1, 1886; Missouri, Boonville, between April 16 and May 31, 1854; Illinois, near Chicago, November 7, 1871; Ohio, Sandusky, November 19, 1925, and Painesville, October 22, 1916, and October 24, 1922; and Wisconsin, Door County, May, 1881. _Egg dates._--Greenland: 18 records, May 16 to June 30; 9 records, June 1 to 19. Iceland: 6 records, May 21 to June 17. Baffin Island; 2 records, July 21 and 28. ARQUATELLA PTILOCNEMIS PTILOCNEMIS (Coues) PRIBILOF SANDPIPER HABITS As explained under the Aleutian sandpiper, this bird is probably not a subspecies of the purple sandpiper; so the name _maritima_ can not be used for either _ptilocnemis_ or _couesi_. I have therefore thought it best to follow Ridgway (1919) in the use of his names for the Pribilof and Aleutian sandpipers, rather than use the Check List names. The Pribilof sandpiper has the most restricted distribution of any North American sandpiper. In summer it is confined to the chilly and foggy uplands of the Pribilof Islands, the equally cool, damp lowlands of St. Matthew Island, Hall Island, and perhaps St. Lawrence Island, all in Bering Sea. And its known migration range is limited to a few localities on the mainland of Alaska and in the Aleutian Islands, where it probably winters. It may breed more extensively on St. Lawrence Island than it is now known to do, but it has not yet been found breeding anywhere on the mainland. G. Dallas Hanna (1921) says: I strongly suspect that the birds have some other extensive breeding ground than St. George, St. Paul, and St. Matthew Islands, because in September and October large flocks come to the two former islands; these appear to contain many more individuals than are in existence on all three. Whether St. Lawrence Island supplies the extra number or not remains for future determination. The winter range of the species is practically unknown, the only records being from Portage Bay, southeast Alaska, and Lynn Canal, between Alaska and British Columbia. The appearance of the birds at the former locality in flocks in spring (if identifications were correct) indicates that they wintered farther south, probably on Vancouver and other islands of British Columbia. They could hardly have come from beyond these localities and have remained undiscovered. _Spring._--The same writer says:
