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. CasroR CANADENSIS CANADENSIS Kuhl. Canadian beaver. 
Castor canadensis Kuhl. Beitrége 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 norvecicus Erxleben. Brown rat; Norway rat. 
Mus norvegicus Erxleben. Syst. Reg. Anim., Vol. 1, 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 LATIMANUS 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.
