have taken it. Dr. Allen makes it stand (Mon. N. Am. Rod.) for the 

 western race of S. niger Linn, as 5". n. ludovicianus (Custis). 



"Virginian Squirrel Sciurus Virginianus." Turton is responsible for this 

 name, which appears, from the description, to be a synonym of one of 

 the S. niger group. 



"NEW JERSEY SQUIRREL SCIURUS H/EMALIS." Undoubtedly named 

 in good faith, but, as the description implies, based on such fanciful 

 characters as any individual of the S. carolinensis group may assume at 

 some period of its existence. 6". hiemalis is a synonym of S. c. penn- 

 sylvam'cus,(Ord), (sup. cit.). 



"Varied Squirrel Sciurus variegatus."=S. variegatus Erxleben, which 

 is based on two or more Mexican species. =5". boothice Gray (List Mam. 

 B. Mus., 1843, 149). For discussion of its synonymy, see Allen, Mon. 

 N. Am. Rod., 1877, 741. 



"Mexican Squirrel Sciurus Mexicanus." This is possibly Spermophilus 

 mexicanus, (Licht.) Wagner. Turton's description indicates this genus, 

 or Tamias, certainly not Sciurus. 



"Hudson's Bay Squirrel Sciurus Hudson/us." This is Pallas' name for 

 the typical northern Red Squirrel or Chickaree. See Pallas, Nov. sp. 

 Glir., 1778, 376. It is strictly a synonym of Erxleben's 5". hudsonicus , 

 (Syst. Anim., 1777, 414), a synonym, however, which later authors have 

 allowed to stand because Erxleben clasified it as a variety of Sciurus 

 vtilgaris Linn. 



Usage may permit, but good rules will not sanction such an interpre- 

 tation. 5". hudsonicus is Erxleben's name, but hitherto Pallas got the 

 credit of it. 



"CAROLINA OR CHICKAREE SQUIRREL SCUIRUS CAROLINENSIS." A syn- 

 onym of Set nrits hudsonicus Erxleben. The name is also preoccupied by 

 the S. carolinensis Linn. (sup. cit.), and by one of Gmelin's synonyms. 



"Fair Squirrel Sciurus flavus." This is one of Linnaeus' original species. 

 Its habitat is given as "Carthagena America." Pennant (Syn. Quad., 

 285.) says "it inhabits the woods near Amadabad the capital of Guzarat," 

 and then quotes Linnaeus as above. It is an unidentifiable species. 



"Flying Squirrel Sciurus volucella."=Sciuropterus volucella (Pallas) 

 Geoff. 



"HUDSON'S BAY FLYING SQUIRREL SCIURUS LABRADOR/US." The 



Flying Squirrel of northeastern N. America, the species here designated, 

 has, either as a species or variety, gone under the names hudsonius of 

 Gmelin (Syst. Nat., i, 1788, 153) and sabrinus of Shaw (Gen. Zool., 

 ii, 1801, 157). Contrary to the arguments of Dr. Allen (Mon. N. Am. 

 Rod., 1877, 660), Shaw's name must hold for the Hudson's Bay race, 

 because Gmelin's Sciurus hudsonius (p. 153, sup. cit.) is only applica- 

 ble to the Chickaree, 5". hudsonicus Erxl. (sup. cit.), to which Gmelin, 

 applies it on a previous page (p. 147) of the same book.
