200 THE GRINNELL WATER-THRUSH. 
ly, as it happened, as Sylvia macgillivrayi, by which specific name it was long 
known to ornithologists. Macgillivray was a Scotch naturalist who never saw 
America, but Tolmie was at that time a surgeon and later a factor of “the 
Honorable the Hudson Bay Company,” and he clearly deserves remembrance 
at our hands for the friendly hospitality and cooperation which he invariably 
extended to men of science.

WHILE we have only one record, and that an old one, there is every 
reason to suppose that this species traverses our borders annually, since it 
breeds in the middle mountain districts of British Columbia (Rhoads), is 
abundant in Alaska (Nelson), and migrates southward thru the western 
United States (Ridgway). The Water-thrush should be looked for in May
