LIST OF DOUBTFUL SPECIES. 
We have above given descriptions of some quadrupeds which we have 
not ourselves had an opportunity of examining— the result of the obser- 
vations of other zoologists— but are not at present able to state posi- 
tively that all of them are founded on good species. 
We add some names of animals that have been given by authors as 
belonging to our Fauna, but which we have not been willing to introduce 
as such into our work, and which may, we think, be safely omitted in 
future lists. 
Sorex Cinereus. — Bach. Young ol S. Carolinensis. 
Ursus Arctos. — Rich. A doubtful species. 
Sciurus Texianus.— Bach. Grey variety of S. Capistratus, without 
white ears. 
“ Occidentalis . — Bach. V ariety of S. Auduboni. 
Arvicola JVuttalli— Harlan. Young Mus leucopus. 
JWus Virginicus. — Gmel. Probably an albino of J\lus leucopus . 
Lepus Campestris. — Bach. This appears to be identical with S. Town- 
sendii, and we should have given the latter name 
as the synonyme. 
Lipuria Hudsonica.— This is supposed to have been a distorted or muti- 
lated skin. There is no animal to correspond 
with the description of it.

Hope.
