SCIURIDA—ARCTOMYS MONAX, 917 
and Forster.* While the ‘Quebec Marmot” of the latter is also certainly 
referable to Spermophilus parryi, the ‘Quebec Marmot” of Pennant is in all 
probability to be assigned to Arctomys monaz, although the ouly really tangi- 
ble character given is, “rather larger than a Rabbet”. The Arctomys empetra 
of Schreber is strictly the Mus empetra of Pallas, Schreber not only quoting 
Pallas’s diagnosis and references, but also giving a figure of Pallas’s Mus em- 
petra, furnished him by Pallas himself, and he based his account of the animal 
mainly on Pallas’s description. He, however, eked out the history of the spe- 
cies by a summary of Pennant and Forster's descriptions of their “Quebec 
Marmot”. Thus, with the exception of the reference to Pennant, the Aus 
empetra of Pallas is the Spermophilus parryi of later writers. Sabine, however, 
in 1822, described a specimen of Arctomys monaz, from Hudson’s Bay, under 
the name Arctomys empetra, to which he referred the Quebec Marmot of Pen- 
nant and Forster, and the several names based thereon, together with the MJus 
empetra of Pallas. The Arctomys empetra of Sabine is properly the A. empetra 
of most subsequent authors down to Audubon and Bachman, who correctly 
referred the A. empetra, as at that time understood, to A. monaz, after having 
seen Hudson’s Bay specimens of the former in England, and becoming con- 
vinced that they were identical. As already stated (see anted, p. 843), Sabine 
noticed the discrepancies between the various accounts of the <Avctomys 
empetra of authors, both among themselves and with his specimen, especially 
the shortness of the tail, as described by Pallas and figured by Schreber. 
These discrepancies were also referred to by Richardson in 1825.t 
The Glis canadensis of Erxleben (1777) is based wholly on the Quebec 
- Marmot of Pennant and Forster, and thus certainly refers mainly to the Arec- 
tomys parryt of Richardson, and (through the reference to Pennant) in part 
also to the A. empetra of Sabine. The Arctomys melanopus of Kuhl was 
based on a specimen of A. monaz, and is thus strictly and exclusively a 
synonym of that species. The ‘ Marmota quebckana Pennant”, cited by 
Pallas, is merely a citation in Latin of Pennant’s English name.
