GENUS ARCTOMYS Schreber. 
; Mus Linn2&US (in | art). 
Glis ERXLEBEN, Syst. Reg. Anim. 1777, 358 (in part). 
Mures soporosi Patuas, Noy. Spec. Glires, 1778, 74 (exeluding his Mus citillus). 
Arctomys SCHREBER, Siiuget. iv, 1792* [prior to 1788], 720 (in part; includes also Spermophilus). 
Arctomys F. Cuvier, Dents des Mam. 1825, 159, 254, pl. liv (based on “ Arctomys alpinus Linn.” and “ Are- 
tomys empetra Pall.”).t 
=“ Theil 1V” of Schreber’s Siingethiere bears the date “1792”, which is probably the date of the 
4 completion of the part, and not of the publication of the earlier fasciculi. Gmelin quotes Schreber in 
id his Systema Naturx, which bears the date 1788, and credits Schreber with the genus Arctomys. On the 
other hand, Schreber first quotes Gmeliu’s work under Hyraz, near the end of Theil LV, and two hundred 
pages beyond Arctomys. The publication of Arclomys by Schreber must have been as early as 1758, and 
may have been several years prior to this date. The deseription of Arctomys oceurs near the end of the 
first third of Theii IV. The date on the title page of Theil III is 1775. 
, tM. F. Cuvier says, at the end of his description of the dentition of Arclomys,—“ Ces dents ont été 
décrites Waprés la marmotte des Alpes, et d’aprés ’empétra de Pallas.” In his “Table méthodique des
