(Proc. Biol. Soc. \Vashn., viii, 1893, 55) to the form of White- footed Mouse 

 inhabiting northern New York and New England, would appear to be 

 preoccupied by the "cauadensis" of Ord. 



"Meadow Mouse Mus arvalis." Turton erroneously includes Newfound- 

 land in the habitat of this Old World species, and Ord follows suit. 



"PENNSYLVANIA MEADOW MOUSE MUS PENNSYLVANICA." While ad- 

 mitting that this name in strictness is justly applicable to Wilson's 

 "Meadow Mouse", Dr. Coues prefers to use Ord's later name of 

 "riparius", stating (Mon. Rodentia, p. 156, foot note) that "the name 

 (pennsylvanica} is simply based, without sufficient description, upon 

 a scarcely recognizable figure incidentally introduced in an ornithologi- 

 cal work." As will be seen, Ord's reference is not made to the figure at 

 all, but to Wilson's description, (Amer. Orn., vi, 59.). which fact Dr. 

 Coues appears to have overlooked. This desciption is a full one and 

 unmistakably applies to the same animal subsequently described by Ord 

 (Jour. Acad. Nat. Sci., Phila., 1825, 305.) with the name riparius. 

 Wilson' figure, good or bad, (and it is poor enough), is of secondary 

 importance. 



Rafinesque's Mynomes pratensis (Amer. Mon. Mag., ii, 1817, 45) also 

 makes it imperative that Ord's earlier name should stand, if Ord is to get 

 the credit due him. Baird incorrectly quotes Ord's pennsylvanica, in his 

 syuonomic list, under Arvicola instead of Mus, and he seems to have 

 been imitated by subsequent writers.

 GENUS ARCTOMYS.

to the same species. The Arctomys empetra of Pallas was originally 

 imposed by him on Parry's Spermophile of Richardson. In Pallas' 

 references, however, he cites the Quebec Marmot of Pennant and Foster 

 as synonyms of the Spermophile. This originated much confusion among 

 later authors, in which Ord has followed Turton. Dr. Allen (Mon. N. 

 Am. Rod., pp. 915-917.) fully discusses these perplexing questions. 



"Hoary Marmot Arctomys pruinosa."=A. priunosus Gmelin. 



''Tailless Marmot Arctomys Hudson/us." Founded on "No. 265, Tailless 

 M." of Pennant (Hist. Quad., 1781, 405) whom Turton copies and imposes 

 the binomial. I find no subsequent reference to it in literature. It 

 seems unidentifiable, being described as having two upper and four lower 

 cutting teeth and no tail : "inhabits Hudson's Bay. In the Leverian 

 Museum." It is not impossible that it was a Lagomys from the Hud- 

 son's Bay Territory. 



"Earless Marmot Arctomys citillus. " Ord has made a pencil footnote, 

 "not in America," under this species.
