Natural History of the Mammalia of India and Ceylon

Semi-Plantigrades

These form part of the Plantigrada of Cuvier and part of the Digitigrada; they walk on their toes, but at the same time keep the wrist and heel much nearer to the ground than do the true Digitigrades, and sometimes rest on them. Of those Semi-plantigrades with which we now have to deal there are three sections, viz., the Mustelidæ, containing the Gluttons, Martens, Weasels, Ferrets, Grisons, &c., the Melidæ, Melididæ and Melinidæ of various authors: i.e. Badgers, Ratels, and Skunks; and the Lutridæ or Otters. Some writers bring them all under one great family, Mustelidæ, but the above tripartite arrangement is, I think, better for ordinary purposes. To the mind of only moderate scientific attainments, a distinct classification of well-defined groups is always an easier matter than a large family split up into many genera defined by internal anatomical peculiarities.

Of the Semi-plantigrades at large Jerdon remarks: “None of them have more than one true molar above and another below, which, however, vary much in development, and the flesh tooth is most marked in those in which the tuberculate is least developed, and vice versa. The great and small intestines differ little in calibre, and many of them (i.e. the family) can diffuse at will a disgusting stench.” This last peculiarity is a specialty of the American members of the family, notably the skunk, of the power of which almost incredible stories are told. I remember reading not long ago an account of a train passing over a skunk, and for a time the majority of the passengers suffered from nausea in consequence. Sir John Richardson writes: “I have known a dead skunk thrown over the stockades of a trading port produce instant nausea in several women in a house with closed doors, upwards of a hundred yards distant.” The secretion is intensely inflammatory if squirted in the eye.
