ON THE DENTITION OF METALOPHODON. 
By Epwarp D. Cope. 
' (Read before the American Philosophical Society, September 20, 1872.) 
This discovery of a second species allied to Bathmodon, Cope, repre- 
sented by more complete remains of dentition than that on which that 
genus was originally established (B. radians), renders it possible to en- 
large our knowledge of its characters. 
It may be premised that the new species may belong to the group 
Loxolophodon, and, as its characters differ from those of the large species 
Hobasileus cornutus, furcatus and pressicornis, 1 must retain the last 
named genus with characters ascribed in my last paper to the former, 
and withdraw the species from the former, to which I at that time re- 
ferred them. It appears that this name, used first for a section of 
? 
Bathmodon, was, perhaps, based on mandibular teeth alone, which in 
Metalophodon, differ remarkably from the maxillaries. The cranium of the 
new species to be described was so decayed as to be irrecoverable, but 
the teeth obtained were in place, and in close proximity, so that there 
can be no reasonable doubt that they belong to the same animal. 
The species differ considerably from the B. radians. 'The most promi- 
nent are: first, the failure of the lateral or straight limbs of the
