{Zool. Jour., 1828. 517.), and the N. occidentalis "Cooper, Mss." (Baird, 

 Proc. A. N. Sci., Phila. , 1855, 335 ) were applied to the same species. 

 These have been revived as subspecies of N. cinerea, the first by Dr. 

 Merriam (Proc. Biol. Soc. Washn., 1892, 25.) as inhabiting the Rocky- 

 Mountains of British Columbia, the second by Dr. J. A. Allen, (Bull. 

 Amer. Mus. N. Hist., 1891, 287.), with habitat in "Idaho and Shoalwater 

 Bay, Washington." The habitat of N. cinerea (typical) is the east slope 

 of the Rockies near Great Falls, Montana. See Coues' Lewis & Clark, 

 1893, pp. 400, 863. It probably extends much farther north, into 

 Alberta, B. America. 



"Rustic Mouse Mus agrarius." Turton, under this name, includes a 

 "No. 2," equivalent to the "No. 230 a" or American Rat of Pennant 

 (Syn., Quad., 1771, 303.) which (sup. cit.) is the White-footed Mouse, 

 A/us agrarius var ainericaniis=Sitomys americanus (Kerrl. It is prob- 

 able that Ord intentionally applied this name, (Mus agrarius}, to the 

 Pennsylvania W. F. Mouse, not considering it separable from the 

 European animal. His "Mus Americanus"^ the American Rat, No. 

 299 of Pennant's History of Quadrupeds, is, as we have seen, (sup. cit.), 

 widely different. 



"Mexican Mouse Mus Mexicanus." Turton's brief description, "A large 

 reddish brown spot each side the belly. Inhabits Mexico, whitish 

 mixed with red," is from Pennant, (Hist. Quad., 1781, 446), who quotes 

 Seba (Thes. Mus., 1734, 74, Tab. xlv, fig. 5.). Seba's figure looks like 

 that of a House Mouse or a species of Reithrodontomys. The peculiar 

 color-pattern, if diagnostic of an indigenous species, should make its 

 recognition an easy task. It is probably a partial albino. 



''Virginian Mouse Mus Virginianus,"" is another production of the inde- 

 fatigable Seba, which Pennant recognizes in his History of Quadrupeds. 

 The type of this creation was probably the result of albinism and out- 

 rageous stuffing, being described as a white "Rat" (mouse?) with base 

 of tail very thick. It may have been a mole. 



"Hudson's Mouse Mus Hudson/us." This is an Arviroline animal de- 

 scribed under the same name by Pallas (Nov. Sp. Glires, 1778, 208.) wlic- 

 quotes Foster. It is not a Zapus, as its specific name would suggest, but 

 (see Coues, Mou. N. Am. Rod., 1877, 249) a synonym of Mus torquatus 

 Pallas (sup. cit., pp. 77 & 206). Should it be proven that the American 

 and Asiatic animals are separable, (Dr. Coues considered them identical), 

 the Mus hudsonius of Pallas will still apply to the former as Cuniculus 

 hudsonius (Pallas), (Coues, Mss.). 



"AMERICAN WANDERING MOUSE MUS CANADENSIS." By the reference 

 of Dr. Coues, (Mon. Am. N. Rod., 1877, 50) it appears the vernacular 

 part of this name was applied originally by Barton ("Med. & Surg. 

 Jour., 1805, 31") to the White-footed Mouse Sitomys americanus (Kerr). 

 I am unable to find the Journal referred to. If certainly identifiable as 

 such, the subspecific name "canadeitsis," applied by Mr. G. S. Miller Jr.
