depressions of dentine. (BENNETT Zool. Soc. I. 1833, P- 6 )- 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. 3 r, fig. i ; the hare, le lievre, 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. Sdugth. Tab. 235 A, B; the mountain-hare, ears 

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

 SCHREB. Sdugth. Tab. 2 36 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 brachyitrus TEMM. from Japan, and 

 Lepus 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 Capro]ogus^. Ann. and Mag. of not. Hist. XVII.
