that of P. lotor a grayish white, just the reverse of what is stated by.the above authors. The 
greater purity of the white marks on the face in P. hernandezti I have not been able to appreciate. 
Of the existence within the limits of the United States of the Procyon cancrivorus, as stated 
by Audubon and Bachman, I can find no trace. The figure given by these authors is taken 
from a specimen in the British Museum brought from South America, and the description from 
one in the Charleston Museum, likewise extra limital. Their notice of the habits and peculiari- 
ties of the California raccoon refers, in all probability, to the P. hernandezit, as this is the only 
species yet detected among the many California raccoons brought in by the different expeditions. 
The P. psora of Gray, from the Sacramento river, is, I suspect, a bleached or faded specimen 
of the same species, with a mutilated tail, as the generic characters of Procyon are partly 
wanting. 
The P. obscurus and brachyurus of Wiegmann I am not able to identify ; it is quite probable 
that they do not belong to North America. The characters assigned of very indistinct annula- 
tion on the tail of the one, and of extreme brevity of tail in the other, are scarcely sufficient to 
establish them as true species. 
From the evidence at present at our command, it would seem that the Mexican raccoon is 
abundant as far north as the Rio Grande of Texas, and west to the Pacific, where it ranges 
north as far as Cape Flattery, or Puget’s Sound, and possibly even further. The line of demar- 
cation between this and the P. lotor to the eastward is not yet ascertained.
