On the PoJJll Bones of Quadrupeds. 415 



o\ A grinder with two tranfverfal eminences, in the pof- 

 ielfion of Cit. Gillet, and of which a germ is preferved in 

 the National Mufeum. It has no refemblance to the teeth, 

 nor to the germs of the teeth, of any animal, whether living 

 or in a foffil ftate, hitherto known. The only teeth to 

 which it bears a refemblance is the laft lower grinder of 

 the rhinoceros. This tooth indicates, then, the exiftencc 

 of a fixth foffil fpecies analogous to no living animal 

 known. 



7. The animal, twelve feet in length and fix in height, 

 the flceleton of which was found below the earth in Para- 

 guay, and is now preferved in the Cabinet of Natural Hif- 

 tory belonging to the king of Spain at Madrid. By a mi- 

 nute companion of the bones of this Ikeleton with thofe of 

 all the known quadrupeds, the author proves that it is a pe- 

 culiar and diiiinct fpecies, which approaches nearer to the 

 iloth than to any other kind, and that it might be named 

 the giant-iloth. Cit. Cuvier here mentions, occafionally, 

 an interesting difcovery Le has made, that the a'<", or three- 

 toed floth {bradypus tridaclylus, Lin.) has naturally and 

 -invariably nine cervical vertebra;. This is the firfl known 

 exception to the rule cfiablifhed by C. Daubenton, that all 

 the viviparous quadrupeds have neither more nor lefs than 

 feven cervical vertebne. 



8. The animal, remains of which are found in the ca- 

 verns near Gaylenreuth and Muggendorf, in the margraviate 

 of Bayreuth in Franconia. _ Several have confidered this 

 animal as a fea-bear ; but it differs from it, as well as from 

 all the bears known, in the form of its head, characterised 

 above all by the projection of the forehead; the want of 

 the fmall tooth, which the bears hitherto known have be- 

 hind each canine tooth ; by the offeous canal of the hume- 

 rus, through which the tracheal artery paffes ,• and by 

 feveral other eircumilances in the figure and proportion of 

 the bones. It is however to the bear that tins animal has 

 the greateft affinity. 



9. The carnivorous animal, bones of which are found in
