name was adopted by Linnaeus in 1754, who describes the species and 

 cites the descriptions and figures of both Catesby and Edwards, and refers 

 to no others.* In the tenth edition of the Systema Naturae (1768), Linnaeus 

 again describes his Sciurus striatus, of which he suys, " Habitat in America 

 scptcntrionali sub terra", and cites only Catesby, Edwards, and Kalm. 

 His diagnosis is changed to read " ^.Jlavus striis", etc., instead of " Sciurus 

 pallUlm striis", etc. In the twelfth edition of the same work, he gives its 

 range as including Siberia, but his first reference is to his original descrip- 

 tion of Sciurus striatus (now further emended to read " S. Jiavus striis 

 quinque fuscis longitudinalibus"), already cited ; his second is to G. Gmelin's 

 Sciurus minor virgatm,\ which refers to a Siberian animal, Gmelin under 

 this head giving the first description of the Europeo-Asiatic form of T. 

 asiaticus. His other references are to Catesby, Edwards, and Kalm, 

 whose descriptions refer exclusively to the Striped or Ground Squirrel 

 of the Atlantic States. Pallas, in 1778, described the Siberian animal under 

 the same name {Sciurus striatus). Although his description is based wholly 

 on Siberian specimens, he also refers to S. striatus the American species, 

 which he states he had not seen and knew only from authors, but from their 

 accounts of it he considered it as evidently the same animal. Thus two dis- 

 tinct species became thoroughly confounded under the same name. Gmelin, 

 in 1788, made ti)e first division of the group, separating the Asiatic and 

 American animals as varieties. The former is his Sciurus striatus, a. asiati- 

 cusz= Sciurus striatus Pallas, exclusive of his synonyms; the latter is his 

 Sciurus striatus, /3. americanus=: Sciurus striatus of Cutesby and Linnaeus 

 (Mus. Ad. Frid. and 10th ed. Syst. Nnt.). In respect to the distribution of 

 these tbrms, he says: — "Habitat a) in omni Asia boreaii ad fluvio.9 europaeos 

 Dwiiia et Kama usque, /?) in America septentrionali magis orientali minusque 

 frigida ad novam Ilispaniam usque.'' The references to the Siberian animal 

 are properly brought together under the head of asiaticus, and the references 



S. ttjialiu or to S. <uiaHo»i via. quairivittatut cannot weU be determinetl. From the len^tk of the tail, it 

 would Beem more lllcely to be tbe latter.
