MAMMALS—-MARTIN AE—MUSTELA PENNANTII. 
149 
MUSTELA, Linn. 
Mustela, Linn. “ Systema Naturae, I, 1735.” 
Teeth 38. Molars one above, two below ; premolars, four above and below, on each side. Lower sectorial tooth with a small 
internal tubercle. Body slender ; tail rather long. 
This genus embraces the martens in distinction from the weasels; species usually of large 
size, arboreal habits, and (some of them at least) yielding furs of great value. They are scat¬ 
tered over many regions of the globe, only two of them belonging to the continent of North 
America. One of these, M. pennantii, is the largest of the known species; the other, M. 
americana, is a near representative of the pine marten of Europe, and in some of its varieties 
of the sable, M. zibellina, of the old world. 
The dental formula of this genus is—incisors, ; canines, ^; premolars, ^; molars ^ ^ 
= 38.
