Most of these characters have to do with degree of inflation of the bullae.
The bullae are less inflated even than in the mink, subgenus Lutreola.
The bullae are, therefore, relative to the basilar length, longer in primulina.
Otherwise, the bullae agree with those of the type specimen.
Specimens from five miles south of Cotopaxi also have the bullae more flattened ventrally.
Even so, the minimum size of bullae among the topotypes is larger than the maximum size in the specimens from Wapinitia.
The bullae are less inflated in southern than in far northern (arctic) populations of Mustela erminea.
The bullae are relatively much inflated throughout but especially so on the posteromedial parts.
Because of their elongation the bullae resemble, in some degree, those of the ocelot.
Most of the ladies did the same by their ornaments, with the bullae 99, and mantles of their children.
