Diacodexis laticuneus Cope (Fig. 24, dc), is a small species, 
Fic. 23.—Anacodon ursidens Cope, inferior molars from above, three-fourths nat. 
size. Original; from the Wasatch epoch of Wyoming. 
Horn region of Wyoming 
(Fig. 24), The skull is prob- 
ably as large as that of a gray 
fox. If properly placed in 
this family, it is the most spe- 
cialized form, on account of 
the bicuspid premolar teeth.

single genus Meniscotherium.

ily of the Condylarthra, úni Terrs., Vol. 111. ; 
one which superadds to its general structure a considerable, 
specialization of the molar teeth. The present genus is the only 
one of the family yet known, and it is represented by but three spe- 
P. With present knowledge it must be asserted that the range 
of this genus was limited both in time and space. The remains 
of the species have been derived from the Wasatch beds of New 
pen and from a horizon from near its base which overlies the 
of th 0. The genus has not been found in any other of the areas 
e Wasatch deposits, but it occurs abundantly in its locality,
