Bemarks. — In certain conditions of pelage Mustela puforius 

 bears a superficial resemblance to Marten foina, though the two 

 animals may always be distinguished by the different form of the 

 ears. Two geograpliical races ai-e at present recognized, though 

 their status is far from well understood. 



The ferret, Martcs furo Linnaeus,* though usually assumed to 

 be a domesticated variety of Mustela j^yutoriiis, 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 buUte, and the smaller size of the carnassial 

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

 of ferrets that I have exandned may at once be distinguished 

 from those of Mustela putorlus, but which render them practically 

 identical with those of the Eastern form.
