Smaller specimens from the Missouri river and west differ from P. noveboracensis in a greater 
extent of the light color on the belly, and in having this of a very decided pale saffron yellow. 
The chin and under surface of the head, however, are white. 
with a greenish tinge. 
The upper parts are lighter, and 
Winter specimens are pure white, with black tip to the tail. 
Their general appearance is much the same with that of number 225, although they are 
smaller; the shade of brown above, and other features, are very similar. There is nearly the 
same indistinctness in the line of separation between the colors of the back and belly, the more 
yellowish tinge generally. The light color of the belly is considerably wider in all these than 
in P. noveboracensis. 
Tf all the specimens of long tailed ermines from the Missouri region differ from the New 
York species, as I am inclined to suspect, then it is the more probable that they are the same 
with the Carlton House variety with long tail, referred to in Richardson’s Fauna Boreale- 
Americana, as quoted above. I have little doubt that the two large species I describe are 
different ; should they prove the same, however, then Bonaparte’s name must be retained as 
having priority.
