COLUMBIAN BLACK-TAILED DEER. 
31 
party again found them abundant when they reached the hills near the 
Sierra Nevada, on their way towards the Chinese diggings, about eighty 
miles southeast of Stockton. 
They may be said to inhabit most of the hilly and undulating lands of 
California, and as far as we can judge probably extend on the western 
side of the grand ridge of the Rocky Mountains nearly to the Russian 
Possessions. 
We have not heard that they are met with east of the bases of that 
portion of the Cordilleras which lies in the parallel of San Francisco, or 
north or south of that latitude, although they may exist in the valleys of 
the Colorado of the west in a northeast direction from the mouth of that 
river, which have as yet not been much explored. 
GENERAL REMARKS. 
According to our present information, there is only one specimen of 
this Deer in the collections of objects of natural history in Europe, and 
this is in the museum of the Zoological Society in London, where it was, 
when we saw it, (erroneously) labelled C. Macrotis. 
At the Patent Office in Washington city there is a skin of a Deer (one 
of the specimens brought from the northwest coast of America by the 
Exploring Expedition), which has been named by Mr. Peale C. Lewisii. 
We have not positively ascertained whether it be distinct from our C. 
Richardsonii, but presume it will prove to be well separated from it, as well 
as from all our hitherto described Deer, and we shall endeavour to figure 
it, if a good species, and introduce it into our fauna under the name given 
it by Mr. Peale. 
We have detected an error in the description of the horns of C. Macrotis 
(see vol. ii. p. 206), where a portion of the description of those of C. Rich- 
ardsonii seems to have been introduced by mistake.
