It proved to be a fine female specimen of Abert'a squirrel In the graj pelage; and I subsequently learned from others who have hunted them In this localli;, where they are by no means abundant, that they are sometimes taken where their fur is of a jetty black, with the tail broadly bordered with snowy white, and perhaps similarly marked on the breast and lower parts.
Old hunters who have had the opportunity of ob- serving its habits, say that it differs but little from the ordinary gray squirrel of the eastern states. In this region it is conBned to the mountainous belts of the great pine- trees, la which It spends most of ' its time, rarely descending to the

Specimeus have been taken exhib- iting the various Intermedial stages of coloring between the black and the gray; and it is said that the black variety is a wonderfully hand- some animal, with its long, wavy white emargined tail, and its fantas- tic ear-tufts.
The gray one, which I shot on the day referred tu, I think is, without exception, specimen of the fiuest squirrel in the fauna
��aspects of ear-tufts, and a median broad stripe from shoulders to near root of tail, of a brilliant chestnut. Ear-tufts ian^, com- posed of straight black hairs. Entire under parts, borders of tall, clrcnm-ocular stripe, and upper sides of feet, pure white. A rather broad dividiDg-line at either side, between the white of under part« and gray above, jetty black. Central hairs of tali, for Its entire length, also black, forming a mid-third stripe down the member. i' , ' Claws horn-color and curved.

��The article displays such a monstrous disregard or Ignorance (or both} o( the literature of the subject of which it treats, and so fully Imtrays the author's misconception of the numerous species that have been descril>ed from the region In question, that it would not even call for n protest, were it not for the air of respectability which [a given to it by the cover of the American journal of science.
Little can and need be said in response to a thesis which mainialDS that there is not sufficient evidence to prove that the Vicksbui^ beds overlie the Clai- home sands, and that, as a matter ot fact, the latter will he found overlying the former, when not a par- ticle of evidence is brought forward in support of this statement.
