This small collection is interesting, as exhibiting several forms 
of Suiline, and Tapiroid Pachyderms, the former of which group, 
was heretofore entirely unrepresented in our fossil fauna: of the 
latter only a single species was known, the Harlanus americanus 
wen, (Sus americana, Harlan.) Bones of a small Pachyderm, 
considered identical with Tapirus americanus have been dug up 
in Texas and Louisiana.

tion with an acute oblique elevated line 
Which is met on the anterior edge by a 
similar less elevated one belonging to 
the internal surface. This second line 
is angulated at its basal extremity, 
and there unites with a third line, al- 
most parallel with the anterior margin. 
This margin is a little worn for one 
half the length of the exserted portion. 
‘n the superior maxilla, there are three

closely connected with the transverse ridges by slight elevations, 
Which run obliquely inwards. There is no internal basal mar-
