skeleton, but without cranium or teeth; hence most of its charac- 
ters remain unknown. The very short cervical vertebra which 
belongs to it serves to distinguish it from other genera. A sec- 
ond specimen (Æ. furcatus) found near the first, may belong to it ; 
it includes a fragmentary cranium, but unfortunately no cervical 
vertebrz. Its introduction into this genus is therefore purely 
arbitrary. 
The typical species is of large proportions, only second in size 
to the Loxolophodon cornutus. Its limbs were more slender in 
their proportions. It is in this species that I find much evidence 
in favor of the presence of a proboscis of greater or less length. 
Should several of the other cervical vertebrae have been as short 
as the one preserved, it is evident that the animal could not pos- 
sibly have reached the ground with a muzzle so elevated as the 
long legs clearly indicate. In the species of the other genera, 
where the cervical vertebre are longer, this may have not been 
the case. 
The bones of this species were discovered by the writer in an 
amphitheater of the bad lands of the Washakie basin, known as 
the Mammoth buttes, in Southwestern Wyoming. They were in 
greater or less part exposed, lying on a table-like mass of soft 
Eocene sandstone. A description of this remarkable locality is 
given in the Penn Monthly Magazine for August, 1872. 
The Eobasileus furcatus is principally represented by a skull in 
which the most important features have been preserved. As in 
all the species of Uintatherium in which the horns are known, 
these appendages stood in front of the orbits, it is probable that 
such was the case in the Zodasileus furcatus also. The muzzle is 
materially shorter and more contracted, and the true apex of the 
muzzle was not overhung by the great cornices seen in Lorolo- 
phodon cornutus. The occipital and parietal crests are much more 
extended in this species than in the Z. cornutus, so that in life the 
snout and muzzle had not such a preponderance of proportion as 
in that species. All the species of this genus were rather rhi- 
nocerotic in the proportions of the head, although the horns and 
tusks produced a different physiognomy. 
The known species of Loxolophodon Cope, are the largest of 
the order. Three species are known to be distinct: the Z. cornutus 
Cope, L. galeatus Cope, and L. spierianus Osborn. They differ in 
the form of the horns and in the shape of the occiput.
