60 Miller Description of a New White-Footed Mouse 



tail itself, 3J inches." Thus color and measurements alike refer 

 to *S y . americanus. Moreover, two white-footed mice kindly sent 

 me in the flesh by Mr. I. R. Bourchier, of Button, West Ontario, 

 Canada, just south of Lake Sirncoe, are perfectly typical of the 

 smaller form. 



Arvicola emmonsii De Kay, from Massachusetts (in Emmons' 

 Report on the Quadrupeds of Massachusetts) is clearly a syno- 

 nym of americanus. The color is given as simply " brown above, 

 darker along the back than the sides," but the whole length is 

 stated to be 6 inches ; tail, 2.5 inches. This animal is said to 

 inhabit ''meadows and wooded places. It is often seen in //V/Jx 

 recently mowed, and is known by the name of Deer Mouse " 

 (italics mine). Sitomys americanus canadensis never occurs in 

 fields and meadows, where, however, S. americanus is often found. 



Wagner's Hesperomys maniculatus (Wiegmann's Archiv., xi, 

 1845, Bd. i, 148 *), from the Moravian settlements in Labrador, is 

 described as " supra fuliginoso brunneus * * * Korper 3" 

 2'", Schwanz 2" 5"'." In Beitriige zur Kentniss der Saugthiere 

 Amerikas (Abhandl. Ak. Wiss. Wien, 1848, 315, 316) the author 

 gives practically the same diagnosis, followed by the remarks : 

 " Gestalt, Grosse und Farbenvertheilung verhiilt sich wie bei H. 

 leucopus, so dass ich nur die DifTerenzen anzugeben brauche, 

 welche sich zwischen ihr und dem letztern, von dem ich der- 

 malen nur Beschreibungen, und zwar zuniichst die Richardson's 

 vergleichen kann, ergeben. Diese Abweichungen bestehen darin, 

 dass bei H. maniculatus die Oberseite weit triiber gefiirbt ist, 

 indem sie namlich bios russig gelblichbraun und schwarz ge- 

 sprenkelt ist, ohne Beimischung von Rostroth vie es von //. 

 leucopus angegeben wird." This description is someAvhat puz- 

 zling, and without specimens from the coast of Labrador it is 

 impossible to decide just what animal it refers to. That S. cana- 

 densis is not Wagner's animal is shown by the measurements, 

 which being taken from " 2 Weingeist Examplaren " must be 

 fairly accurate. 



Hesperomys campeskris Le Conte, from New Jersey, is described 

 so vaguely (Proc. Ac. Nat. Sci. Phila., vi, 1853, 413) that, to use 

 Professor Baird's words (Mam. N. Am., 1857, 485) : " Of the affini- 

 ties of this animal I will hazard no conjecture." That it is not 

 the same as S. canadensis is shown by the measurements length,
