level of foramen ovale. Teeth 34 (i. 3/3, c. 1/1, pm. 3/3, m. 1/2); upper car- 
nassial robust, width of its cutting portion about half of length, anterior cusp 
so developed that its greatest height is nearly three-fourths length of outer 
border of tooth; posterior cusp greatly reduced, appearing as a mere thicken- 
ing of posterior margin of crown ; inner lobe of carnassial much wider than in 
Mustela, its posterior border extending about to middle of crown; upper 
molar elongate-pyriform, the outer portion only a little narrower than inner, 
the median constriction slight, axis of crown strongly oblique to median line; 
protocone, paracone and hypocone small but distinct, metacone barely 
indicated; lower carnassial essentially as in Martes, metaconid small though 
evident, but posterior heel smaller, its area less than half that of cutting 
portion of crown. External form polecat-like; fur rather soft and dense, 
varied with black, brown, and whitish or yellowish. Tail about half as long as 
body, bushy. S. E. Europe to central China.

never spotted, rarely (in certain Asiatic species) with median dorsal stripe. 
Skull in general resembling that of Martes, but rostrum so shortened that 
distance from orbit to gnathion is less than width of rostrum between ante- 
orbital foramina; auditory bulla without meatal tube, its outline variable but 
never flask-shaped; paroccipital process small and flattened, closely applied 
to posterior margin of bulla. Teeth 34 (i. 3/3, c. 1/1, pm. 3/3, m. 1/2) ; upper 
carnassial as in Martes, its posterior cusp low but well developed, the height 
of its main cusp about half outer border of crown ; upper molar between pyri- 
form and pandurate in outline, the constriction evident though not deep, the 
main axis of crown nearly perpendicular to sagittal line; lower carnassial 
without metaconid, the posterior heel crossed by a longitudinal trenchant 
ridge; other teeth essentially as in Martes. External form slender, muzzle 
obtuse, ears low and rounded, legs short, tail variable in length and in quality 
of hair, but never so bushy as in Martes. Northern hemisphere from the

Mamm., 98-111) divide the genus Mustela into the three subgen^a Mustela, Lutreola, and Putorius; others 
(as Cabrera, 1922, Man. Mastozool., 201) use Mustela and Putorius as genera; still other authors use Mustela, 
Putorius and Lutreola as genera. Under the circumstances we follow the same system we adopted in #413 
Felia, i. e., using Mustela in a broad sense and making the subgenus in question stand out by putting it in 
hftary tjpe.
