HYPOTHETICAL LIST. 745 
migrating in winter to the Eastern and Middle States, the Great Lakes, 
and the shores of the larger streams in the upper Mississippi Valley. 
This bird is partial to rocky shores and cold weather; a late migrant 
and likely to remain on the lake shore until ice forms. While we have 
no actual records for the state, it seems almost certain that the species 
must occur in suitable places, at least occasionally. E. W. Nelson found 
it on the shore of Lake Michigan in northeastern Illinois (Bull. Nutt. 
Orn. Club, II, 1877, 68). One was obtained near Chicago, on the lake 
shore, November 7, 1871 (Baird, Brewer and Ridgway, Water Birds I, 
218). “Dr. Hoy states, in his list of 1852, that this species was abundant 
at Racine from April 15 to May 20” (Kumlien and Hollister, Birds of 
Wisconsin, 1903, p. 45). There are also several records for Ontario 
(Mellwraith, Birds of Ontario, 1894, 138).

Curlew Sandpiper. Erolia ferruginea (Brunn.). (244) 
Scarcely distinguishable from the Red-backed Sandpiper except by 
the expert, but averaging a little larger, with the bill proportionally shorter, 
but of the same shape. 
Distribution.—The Old World in general; occasional in eastern North 
America and Alaska. 
This is an extremely rare bird anywhere in America, and its presence 
in Michigan can be regarded only as accidental. There is said to be a 
specimen in the Museum of the University of Michigan labeled “ Michigan,”’ 
but there is no evidence of its-origin upon the books. Dr. Gibbs states 
that D. D. Hughes records it as taken in 1870 (Manuscript Ornithology 
of Mich.). According to Dr. R. H. Wolcott there should be a specimen 
in the collection of the Kent Scientific Institute at Grand Rapids labeled 
“Detroit, 1869,” but the writer found no specimen whatever of the Curlew 
Sandpiper in the Kent Scientific Museum, after a careful examination 
in November, 1905. It is not improbable that all these records are based 
on immature examples of the Red-backed Sandpiper. , 
Western Semipalmated Sandpiper. Ereunetes mauri Cabanis. (247) 
Synonyms: Peep, Western Sandpiper.—Ereunetes occidentalis, Lawr. 
In plumage so like the ordinary Semipalmated Sandpiper as to be separ- 
able only by the expert: but the bill of the western bird averages decidedly 
longer, measuring .88 of an inch in the male and 1.05 in the female, so that 
if specimens are carefully sexed there should be no trouble in separating 
them. 
Distribution.—Chiefly western United States, frequent eastward to 
the Atlantic coast; breeding far north and migrating in winter to Central 
and South America. 
So far as we can find, this species, or subspecies, has not been recorded from 
Michigan; but, since it occurs in some numbers to the eastward, and has 
been taken regularly on Lake Koskkonong, Wisconsin (Kumlien and 
Hollister, Birds of Wisconsin 1903, 48), there is some probability that it 
might be found in Michigan during migration if carefully sought.
