As has beeu remarked by Professor Baird, it is not a little singular 

 that an animal described -with such detail by these authors was not 

 named hy early writers like Ord, Eafmesque, and Harlan, though other 

 species were so promptly introduced into the system ; but 1 have seen 

 no name for the species earlier than that bestowed by Peale.

This animal is said to be common in all timbered portions of the Eocky 

 Mountains. Prom the description, especially the mention of the black 

 stripe along the sides, it is clearly one of the ^S*. lindsonius group, but it 

 is difficult to fix it precisely. As, however, the *S'. donglassii is the one 

 evidently referred to under the name (see below) of "Small Brown 

 Squirrel," we may suppose, upon the principle of exclusion, that by 

 "Small Gray Squirrel" the authors meant the one subsequently named 

 S. richardsoni by Br. Bachman.

Isotwithstauding that the authors' description of this animal is one of 

 the most elaborate and extended of the whole series, it has occasioned 

 misunderstanding, and given rise to numerous synonyms. The first 

 author to take up the account seems to have been Ord, who bases his 

 Arctomys columhianus upon the animal, and quotes Lewis and Clarke at 

 length. In 1817, Eafinesque, upon a misconstruction of a phrase used 

 by the authors, based his genus Anisonyx with the species A. brachiura. 

 In treating of C. gunnisoni, which he had named in 1855, Professor Baird, 

 in 1857, discussed the applicability of all these names to the Burrow- 

 ing Squirrel of Lewis and Clarke, bringing the Arctomys leivisii of 

 Audubon and Bachman into the same connection. Yery recently, in his 

 admirable review of the Sciuridte, Mr. J. A. Allen has first collated the 

 full synonymy, identifying the several supposed species here mentioned 

 with the animal of Lewis and Clarke.
