NOTE ON BOUNDARIES OF THE REGION TREATED. 



The present report relates to the birds, mammals, and batrachians 

 of the Province of Keewatin, in Canada. But though it has seemed 

 best to thus liniit by geographic boundaries the region treated, some 

 notes from localities outside these boundaries have been included, 

 where such a course has seemed desirable. Thus many references to 

 the birds and mammals observed and collected on the voyages of Ross 

 and Parry have been utilized. It is belie^•ed, however, that all the 

 species thus included will be found to occur within the boundaries of 

 Keewatin. A few old references to the occurrence of species on Hud- 

 son Bay can also be safely referred to Keewatin, since most of the early 

 collections and observations were made on the west coast of the Bay. 

 The lists also contain a few species which have been recorded only 

 from the southern extremity of Hudson Bay, mainly at Moose Factory, 

 a few birds seen by us only on the lower Red River, and a number of 

 birds recorded from Grand Rapids, at the mouth of the Saskatchewan 

 River. A few Old- World species, straggling individuals of which have 

 been recorded from Hudson Baj', have also been included. Since each 

 record speaks for itself, it has not been deemed necessary to indicate 

 ' extralimital ' species by placing them in a separate category or other- 

 wise differentiating them from those seen or taken strictly within the 

 geographical boundaries of Keewatin. 



Additional work, especially in the southeastern part of the Province, 

 will doubtless add a considex'able number of birds and a few mammals 

 to the list of species known to inhabit Keewatin. Thus a number of 

 northern plains species will undoubtedly be found to occur regularly 

 near the Manitoba border, and many birds which are known to occur 

 at a much higher latitude to the westward will probably be found to 

 breed regularly in southern Keewatin. 



Among the numerous published notes relative to many species 

 only those which best illustrate their geographic distribution or sup- 

 plement our own observations have been selected. 



NEW SPECIES. 



The following six new species and subspecies of mammals are 

 described in the present report: 



Microtus aphorodemus. Lutreola vison lacustris. 



Fiber zibethicus hudsonius. ilustela americana abieticola. 



Lepus areticus canus. Sorex (Microsorex) alnorum. 



In addition to these, three others which properlj^ come within the 

 scope of this report have been described since the completion of the 

 trip: 



Phenacomys maekenzii. Vulpes lagopus innuitus 



Synaptomys {Mictomys) buUatus.
