 "Columbia Marmot." 



For an amusing and trustworthy interpretation of the affiliation of 

 Snakes Lizards, Owls and Prairie Dogs, consult Dr. Coues' Birds of the 

 Northwest, 1874, p. 324. Rafinesque named this animal Cynomys 

 socialis in 1817.

 "Louisiana Marmot." 



It seems evident, from the context, that Ord never saw a specimen of 

 this Spermophile but was induced, by the minute description, to risk 

 naming it. 



Dr. Merriam's identification of it has, we trust, settled forever one of 

 the strangest cases of mistaken identity that has arisen in American 

 Zoology.

 Squirrels Discovered by Lewis and Clark. 



This paragraph is important, and to be better understood may be 

 amended as follows : "Our Catalogue, it will be perceived, is enriched 

 with the [vernacular and generic] names of those animals of this genus 

 which were discovered [and described] by Lewis and Clark, the stuffed 

 skins of which have been deposited in Peale's Museum. The history of 

 their [Lewis and Clark's] journey gives an account of some others [sqiiir- 

 rels, chipimunks and sperinophiles] but as this notice [Lewis & Clark's 

 account] is a mere record of their existence [the existence of these ani- 

 mals] w r e are not enabled [in the absence of specimens] to determine 

 whether or no they are nondescripts." It is evident therefore, and the 

 paragraph quoted (supra) from the Journal de Physique confirms it, that 

 Ord did not refrain from imposing specific names on these Squirrels be- 

 cause they were not represented by specimens, but that he was content 

 to defer the final naming of them until he could bring out his illustrated 

 work on the zoology of Lewis and Clark's Journey, spoken of in his let- 

 ter to Blainville.

 Lewis and Clark Deer. 



We have no account that any specimens of these deer were brought 

 to Philadelphia. If there had been, Ord would undoubtedly have given 

 them specific names in his catalogue.
