112 FOSSIL MAMMALIA. 



much resembled those of the swine, approached very near this 

 new genus, and, perhaps, formed the link between it and the 

 anoplotheria proper. 



The Adapis is another of these extraordinary and numerous 

 genera. It is only known by some debris of the head. Its 

 general form appears to have been something like that of the 

 hedgehog, but a third larger. Four incisors were discovered, 

 trenchant, and rather oblique, like those of the anaplotherium ; 

 then, above and below, a conical canine, thicker and rather 

 more projecting than the other teeth ; the upper one a straight 

 cone, the lower oblique, and couched forwards ; the alveolus 

 of the upper was very deep. The molars appear to have been 

 seven in number in each. Six were discovered in the upper 

 jaw, the first trenchant, the second surrounded by a crest, 

 the third apparently so ; the fourth and two last were like the 

 hinder molars of the anoplotherium. In the lower jaw, the two 

 first molars are pointed and trenchant, the third similar, but 

 longer and wider; the three following were wanting in the 

 lower jaw discovered. The last is oblong, and seems to have 

 had the tubercles in the form of unequal transverse hillocks. 

 The animal might have been about the size of a rabbit, and 

 approximated to the anoplotherium. 



The last of these extinct pachydermata is the Antraco- 

 THERiuM. Of this genus two species were discovered in the 

 lignites of Liguria, at Cadibona, near Savone, and a third in 

 the fresh-water formation of the environs of Agen. It is im- 

 possible for us to follow the Baron through his account of these 

 discoveries and of their osteology. The jaw-teeth exhibited 

 considerable analogies with those of the chseropotamus and the 

 dichobunes. But besides that these molars presented of them- 

 selves specific distinctions, the large and projecting canines with 

 which they were accompanied, left no doubt of the existence 

 of a new and distinct genus. The first species approached to 

 the size of the rhinoceros, the second was considerably smaller, 

 and the third rests upon the fragment of a jaw found in the
