Lake St. John and the East Main River ; this may possibly be an- 

 other form, Arctomys monax empetra Pallas. 



23. SCIUROPTERUS SABRINUS MAKKOviKENSis Sornborger. Labra- 



dor flying squirrel. 



Sciuropterus sabrinus makkovikensis Sornborger. Ottawa Nat- 

 uralist, Vol. XIX, p. 48. June, 1900. 

 Type Locality. Makkovik. 



Rather generally distributed throughout the wooded region, 

 though apparently not common anywhere. The Labrador form 

 is a very well-marked subspecies. 



24. CASTOR CANADENSIS CANADENSIS Kuhl. Canadian beaver. 

 Castor canadensis Kuhl. Beitrdge zur Zoologie, p. 64. 1820. 



Low says the beaver is common in the wooded regions, and 

 extends into the semi-barrens, where food is found. I have seen no 

 Labrador specimens. 



25. Mus NORVEGICUS Erxleben. Brown rat; Norway rat. 

 Mus norvegicus Erxleben. Syst. Reg. Anim., Vol. I, p. 381. 



1777. 



Doane took one Norway rat at Black Bay, November 30, 1899. 

 This is the only specimen I ever saw from Labrador. I have never 

 received specimens of the house mouse, Mus musculus Linn., from 

 Labrador, though it must undoubtedly occur there. 



26. PEROMYSCUS MANICULATUS MANICULATUS Wagner. Labrador 



deer-mouse. 

 Hesperomys maniculatus Wagner. Weigmann's Archiv., Vol. 



XI, p. 148. 1845. 



Type Locality. "The Moravian settlements in Labrador." 

 Common throughout the peninsula south at least to Hamilton 

 Inlet. The Labrador deer-mouse, like many of its congeners, is apt 

 to take up its abode in buildings and huts like the house mouse, and 

 in Labrador seems to be much more abundant in such places than 

 in the woods and among rocks. I have examined very large series 

 of this species. 



27. PHENACOMYS LATJMANUS Merriam. Small yellow-faced phena- 



comys. 

 Phenacomys latimanus Merriam. North Am. Fauna, No. 2, 



p. 34. 1889. 



Type Locality. Fort Chimo, Ungava, Labrador. 

 Probably of general distribution in the drier semi-barrens. 

 Known from Labrador only by the specimens sent to Washington 

 by Turner. 



28. PHENACOMYS CELATUS CELATUS Merriam. Large yellow-faced 



phenacomys. 



Phenacomys celatus Merriam, North Am. Fauna, No. 2, p. 33.
