Bemarks. — In certain conditions of pelage Mustela putorius 

 bears a superficial resemblance to Martes foina, though the two 

 animals may always be distinguished by the different form of the 

 ears. Two geographical races are at present recognized, though 

 their status is far from well understood. 



The ferret, Martes furo Linnseus,* though usually assumed to 

 be a domesticated variety of Mustela putorius, appears to be 

 related to the Asiatic M. eversmanni Lesson.f This is shown by 

 the deeply constricted postorbital region, the less triangular, 

 more inflated auditory bullae, and the smaller size of the carnassial 

 teeth both above and below, characters by which the few skulls 

 of ferrets that I have examined may at once be distinguished 

 from those of Mustela putorius, but which render them practically 

 identical with those of the Eastern form.
