depressions of dentine. (Bennett Zool. Soc. i. 1833, P- 60). — The two 

 orbits are perforated by a single and common foramen opticum. The bony 

 palate is very imperfect, and forms merely a transverse strip between the 

 anterior molars. (These peculiarities also apply to the following genus 

 Lagomys.)

 Mammif. PI. 3r, fig. i; the hare, le lilvre, der Hase ; dispersed nearly 

 throughout the whole of Europe ; is not met with in Sweden and Norway ; 

 the ears are longer than the head; the tail white, black above; — Lepus 

 variabilis Pall., Schreb. Sangth. Tab. 235 a, b; the mountain-hare, ears 

 nearly of the length of the head ; tail grey above ; in the summer brown ; 

 in winter white, except the borders of the ears, which remain black; in 

 Sweden, the Swiss Alps\ Scotland and Ireland; — Lepus cuniculus L., 

 Schreb. Sdugth. Tab. 236 a; the rabbit, le lapin, das Kaninchen. The 

 wild rabbits are grey with a ruddy spot on the neck ; the ears are some- 

 what shorter than the head. Lepus brachywrus Temm. from Japan, and 

 Lipus hispidus Pearson, from Assam, are distinguished by the ears shorter 

 than the head and the tail very short; of this last species Bltth has 

 formed the sub-genus Capirologus'^. Ann. and Mag. of not. Hist. XVII. 

 1846, p. 163. On the other species see Waterhouse Mamm, 11. pp. 33 — 

 147. 



Lagomys Cuv. Ears short, rounded. Tail none. (Molar teeth 



5 — 5 



P — p . Clavicles perfect.) 



To this genus belong some small species, mostly from the North-West of 

 Asia. The skull is more elongate and less high in front. Sp. Lagomys 

 alpinus, Lepus alpinus Pall. Nov. Spec. Glir. Tab. 11., Schreb. Sdugth.

 Ogotona of the Mongols, to the South of the lake Baikal, &c. — Lagomys 

 pninceps Richards. Faun. bor. Amer. PI. 19, in North America, Rocky

Many fossil remains belonging to this genus are found in the fissures of 

 the limestone rocks on the coast of the Mediterranean Sea, especially in 

 Corsica and Sardinia.

 Family XXIII. Suhungulata Illig. Molar teeth - — ^ , 



complex or lamellose. Fore feet tetradactylous or pentadacty- 

 lous, hind feet mostly tridactylous, or peutadactylous, with lateral 

 digits small, remote. Claws large, uugular, or compressed, keeled 

 above.

2 Waterhouse writes Carpologus, but the name appears to be derived from the 

 stiff bristles {Kairpos, a hog).
