318 PICTURESQUE SKETCHES 



The teeth of a large species of lion, of a true 

 leopard, of a wild cat, and of another remark- 

 able and little known animal, also of large size and 

 Fig. 137 m ghty carnivorous habits, have been 

 found in the gravel and the caverns, 

 associated with those already described. 

 The teeth of this last-named species 

 quite equal in size the corresponding 

 teeth of the tiger, and indicate an ani- 

 mal of even greater ferocity. The 

 powerful cutting-tooth, curved back- 

 wards like a pruning-knife, and ser-

 in the annexed figure (137), is very 

 different from the corresponding struc- 

 ture in the better known FeUda, and 

 the animal has therefore been referred 

 TOOTH OP to a new sub-genus, under the name of 



MACHAIRODUS. 



The ruminating quadrupeds contemporary with the 

 animals just described included several of the deer 

 tribe, a goat, and at least three species of the genus 

 Bos. One of the latter is probably identical with the 

 great Lithuanian aurochs, still preserved in eastern 

 Europe ; another is a very gigantic species of urus, 

 now most likely extinct ; and a third, smaller than the 

 common ox, has been found in the bogs of Ireland, and 

 also in various places in England in the superficial 

 gravel. Of all these, the remains of the aurochs or bi- 

 son are remarkable for their large size, and their longer 

 and somewhat straighter horns than the existing wild 

 bison, which is a species still preserved in the extensive 

 forests of Lithuania ; but still it does not appear that
