plumage, that a careful examination of the bill and feet is necessary to distinguish it from 

 them. It is much smaller than any of its congeners, and may be distinguished by its 

 short tarsi, which are less than one inch in length. 



It is very closely related to its Western ally, from which it scarcely differs, except in Subspecifio 

 the length of its bill, which varies from "68 to •92 inch, whilst that of the Western form 

 varies from "85 to ri5 inch. The two forms do not differ from each other in colour, 

 except that in summer plumage the Western form is more chestnut on the upper parts. 



The Canadian Semipalmated Stint breeds in the arctic regions of the American 

 continent from the Rocky Mountains to Baffin's Bay, but has not occurred in Greenland. 

 On migration it follows the river-courses, as well as the shores of the Atlantic, and is a 

 regular visitor to the Bermudas (Reid, Zoologist, 1877, p. 476). It winters on the coast 

 of the South-American continent. I have several examples from Cayenne and Bahia, and 

 one collected by Capt. Harrison in Unevo Gulf (about lat. 43° south) on the coast of 

 Patagonia, which appears to be the southern limit of its range on the east coast. On the 

 west coast it has been recorded as far south as Paracas Bay in Peru (Salvin, Proc. Zool. 

 Soc. 1883, p. 429), but it is probable that the record refers to the Alaskan form of this 

 species.
