. Cuvier's animal kingdom : arranged according to its organization. Animals. RODENTIA. 115 progress, they devastate the coimtry through which they pass. Their ordinary residence appears to be the shores of the Arctic Ocean. The Siberian Lemming, or Zocor (il/!M aspalax, Gm.)—Reddish-grey ; the three middle nails of the fore-feet long, prcuated, compressed and trenchant, for cutting earth and roots. The limbs are short ; there is scarcely any tail ; and the eyes are exceedingly small. From Siberia, where it lives under-ground, like the Jloles and Mole-rats, and subsists chiefly on the bulbs of different Liliaceœ. The third species, like the other animals comprehended under the great genus of Rats, has only the rudiment of a thumb to its fore-feet. It is the Hudson's Bay Lemming (Mus Hudsonicus, Gm.) ; of a pearl-grey colour, without any tail or external ears: the two middle toes of the fore-feet of the male seem to have double claws, the skin at the end of the toe being callous, and projecting from under the nail ; a variety of con- formation unknown except in this animal.* It is as large as a Rat, and lives under ground in North America. The Otomyds {Otomt/s, F. Cuv. ; [Euryotis, Brandt] )— Are nearly allied to the Voles, and have also three grinders, but composed of slightly arcuated laminae, which are arranged successively in file, so as to present an exact miniature resemblance to the grinders of the Elephant. Their incisors are grooved longitudinally, and the tail and ears are hairy, the latter being also large. The only known species, the Cape Otomyd (0. capensis, F. Cuv.), inhabits Africa, and is of the size of a Rat, with fur annulated black and fulvous. Tail a third shorter than the body. The Jerboas {Dipus, Gm.)— Have nearly the same teeth as the Rats properly so called, differing only in the occasional presence of a very small tooth, placed before the superior molars. Their tail is long and tufted at the end, the head large, and eyes large and promi
