nearly twice that size. This genus is the type of a distinct family, the Moropodide. 
In the Lower Pliocene above, well-preserved remains of edentates of very large size 
have been found at several widely separated localities in Idaho and California. These 
belong to the genus Morotherium, of which two species are known. East of the Rocky 
Mountains, in the Lower Pliocene of Nebraska, a large species, apparently of the genus 
Moropus, has been discovered. The horizon of these later fossils corresponds nearly 
with beds in Europe that have been called Miocene. In the Post-pliocene of North 
America gigantic edentates were very numerous and widely distributed, but all 
disappeared with the close of that period. These forms were essentially huge sloths, 
and the more important genera were Megatheriwm, Mylodon, and Megalonyx. The 
genera Megalocnus and Myomorphus have been found only in Cuba.”

and Ancylotherium, and gives numerous figures in the text.

Deodon shoshoniensis is described as the type of a new genus and species of Chali- 
cotheres from the Miocene of Oregon. The author states that it is allied to Menodus 
and Symborodon. (Deodon is an entelodont. Cf. Peterson, Memoirs Carnegie 
Museum, Vol. IV, p. 63.)

“ Bdentés.—L’étude de quelques métacarpiens trouvés 4 Limogne m’a permis de 
découvrir l’existence ancienne d’un nouveau genre d’édenté. L’animal dont provien- 
nent les os qui m’ont été remis avait une taille puissante, car son troisiéme méta- 
carpien mesure 0.180 de longueur. La forme des extremités articulaires inférieures 
est semblable 4 celles des extrémités inférieures des métacarpiens du Macrotheriwm 
giganteum, mais les surfaces carpiennes sont absolument differentes. Le premier doigt 
parait ne pas avoir existé. Le troisiéme métacarpien s’articulait avec le grand os et 
peutétre avec le trapézoide.”’
