The Loxolophodon spierianus Osborn, was as large an animal as 
the two others, and had a very elongate skull with weak horns and 
narrow, high occiput. Its median horns are situated well ante- 
rior to the orbit, and its zygomatic fossa is remarkably small. It 
was discovered by the Princeton scientific exploring party at the 
same locality that produced.the other species, viz., the Mammoth 
buttes of Southwestern Wyoming (Fig. 28) 
In the Z. cornutus and L. galeatus the tuberosities which stand 
Fic, 29.—Loxolo gos cornutus Cope, skull of individual represented in Plate 1, 
one-eighth nat. size. Upper figure superior surface; lower figure inferior surface. 
From Bridger Eocene of Wyoming. Original, from "anion U. S. Geol. Survey of 
Terrs ayden in charge, Vol. 111. Owing to distortion of the specimen be- 
hind, ‘the occipital condyles are too far apart in figure. 
near the free extremity of the nasal bones are greatly developed, 
so as to represent a pair of cornices projecting upwards and for- 
wards over the narrow apex of the bones (Fig. 24). From above, 
the end of the muzzle in those species has a bilobate outline. 
They differ from each other materially in the form of the middle 
pair of horns.
