Rica. It is very dark and richly colored, with the merest trace

I find nothing in the ascribed characters of Mustela macrura 

 Taczanowski forbidding its reference to the Middle American 

 series ; nor is there anything in Dr. Gray's brief and unsatis- 

 factory account of 31. affinis incompatible with the characters of 

 the present species in their now ascertained range of variation. 



There is nothing peculiar in the relationships of the various 

 forms as here advanced. It is paralleled in the cases of other 

 Mammals and many Birds, and, in fact, might have been pre- 

 dicated. 



We are in possession of no special information upon the hab- 

 its of the Bridled Weasel, which, however, may be presumed 

 to differ little, if at all, from those of its allies. Dr. Newberry 

 represents it as abundant about San Francisco.
