The specimen is apparently larger than the Alaskan mink, as the average distance between the last incisor to the first molar is 2.8 centimeters (1.1 in) in the Alaskan mink, whereas that distance is 3 centimeters (1.2 in) in the type specimen. The nasal bone has an abrupter ascension, and the carnassial teeth make a more acute angle with the gums than those of the common mink.[1][2]
