13. Tail flattened, with a narrow, fringe-like expansion on each side, 
16. Ptcronura, 
Tribe 3. Enhydrina. 
17. Enhydris. 
II. Platypoda, 
Feet elongate ; toes straight ; claws exserted, hlunt, 
A. Tiantigrade. Soles bald, callous nearly to the heel. 
Tribe 4. Metana. Tubercular grinder large, oblong, elongate. Palate 
produced behind. Flesh-tooth with two more or less distinct tubercles on 
inner lobe. 
18. Arctonyx^. 19. Moles, 20, Taxidca, 21. My dans.

Tribe 6. Mephitina. Tubercular grinder oblong, four-sided. Palate 
scarcely produced behind j hinder opening in a line with the hinder grinders. 
23. Conepatus (Gray)= (Licht.). The various forms described 
by authors are regarded as one species, referable to four varieties. 
24. Mephitis. The author, finding that the extent of baldness of the 
sole varies in different specimens of the same variety, unit.es M. chinga veith 
M. mesomelas and others into one species, keeping only M. vittata (Licht.) 
and M, mexieana (Gray) =ilf. macroura (Licht.) distinct. All have three 
pads in front of the sole of the hind feet.

space in front.

26. Zorilla^ with two species. 
Tribe 8. Helictidina, 
27. Ilelictis^ with four species, two of which, viz. II. orientalis and H. 
nepalensis, are united into the subgenus Melogcdc, because they have the 
flesh-tooth larger, and the aperture in front of orbits [? foramen infraorbitale] 
smaller, than the others. 
Miistcla. Prof. Giebel has published some notes on skulls and skeletons of 
M. piutorius, M. furo, M. vulgaris, M. foina,M. alptina, M, vison. Zeit- 
schr. gesammt. Ntrwiss. xxiv. pp. 470-476. 
Prof. Bischoff has examined the ovum and placenta of M. foina, martes, 
and vulgaris, and discovered a sac-like appendage to the placenta, similar to 
that of Lutra. Sitzgsber. Bayr. Akad. Wiss. Miinch. 1805, i. p. 339. 
Mustela vulgaris. Prof. Costa has described a variety from Southern 
Woodcut of skull, p. 681.
