REVISION OF THE JUMPING MICE OF THE GENUS ZAPUS. 11 



Hudsonius (Dipus) Zimmermaim, Geog. Geschichte des Menscheu n. 

 vierfiissigen Thiere, II, p. 3.~>8, 1780. This is the first specific name pro- 

 posed for any species of .Tumping 1 Mouse in America, and undoubtedly 

 refers to the common eastern species which has so long- borne the name. 

 It is the only species thus far known to occur about Hudson Bay the 

 locality of Pennant's 'long-legged mouse,' to which Zimmerman 11 

 referred. 



Imperator (Zapus) Elliot, Field Columbian Mas., Pub, 30, Zool. Ser., I, 

 No. 11, p. 228, February 1 , 1893. Mr. D. G. Elliot has recently described 

 a Zapus from the Olympic Mountains of Washington, but specimens 

 from that region not being considered separable from typical Z. trinota- 

 tiix, the name becomes a synonym. 



Insignis (Zapus) Miller, Am. Naturalist, XXV, p. 472, August, 1891. 

 Mr. Gerrit S. Miller, jr., described the species erroneously referred to 

 .17. labfftdorius (Z, hudsonius) by Dawson, from specimens collected on 

 the Restigouche Eiver, New Brunswick. 



Labradorius (Dipus) Kerr, Animal Kingdom, p. 276, 1792. Based on 

 the 'Labradore Jerboid Rat' of Pennant's History of Quadrupeds, 1781. 

 Kerr sa} r s, " Inhabits Hudson's Bay and Labradore. This species was 

 sent over from Hudson's Bay by Mr. Grah'am." Although Labrador is 

 mentioned in the habitat of the species, the specimen came from Hud- 

 son Bay, and consequently the name should be restricted to the animal 

 from that region, thus becoming a synonym of Imdsonim. 



Ladas (Zapus) Bangs, Proc. New Eng. Zool. Club, I, p. 10, February 

 28, 1899. Under this name Mr. Outram Bangs has described, as a 

 subspecies, the form of Imdsonius inhabiting the Labrador Peninsula. 



Leonurus (Gerbillus) Rafiuesque, Am. Monthly Mag., Ill, p. 446, Octo- 

 ber, 1818. From the description "body fallow, ears very long, white 

 inside, tail as long as body, black with a fallow tuft at end, length 6 

 inches, body 3'' the animal is plainly not referable to Zapns. 



Longipes (Mus) Zimmermann, in Pennant's Arkt. Zool. I, p. 131, 1787.* 

 Ziinmermann erroneously identified a Jumping Mouse in spirits, sent 

 from Hudson Bay by Mr. Graham, as Mns longipcs of Pallas, an animal 

 from the deserts about the Caspian Sea. 



Macrourus (Gerbillus) ' Rafinesque,' a name referred to by Fischer (Syn. 

 Mamin., p. 340, 1829), without reference, and included in the synonomy 

 of Zi>us by Dr. Coues (Mon. N. Am. Rodentia, p. 468, 1877). I have 

 been unable to find the original reference. 



Megalops (Gerbillus) Rafinesque, Am. Monthly Mag., Ill, p. 446, Octo- 

 ber, 1818. This animal he describes as follows: "Body gray, belly 

 white." * * * "Total length 5 inches, body only 2. From the 

 barrens of Kentucky." This can not apply to any species of Jumping 

 Mouse. 



Mellivorus (Dipus) Barton, Trans. Am. Philos. Soc., VI, p. 143, 1804. 



*Fide Coues, Mon. X. Am. Kodcntia, p. 4t>7, 1877. I have not seen this edition of 

 Pennant.
