this molar in the ox family. Its 
crown is much worn, and the 
internal segments of enamel are 
very small; in the anterior half, 
the segment is of an elongated « 
oval form, while in the posterior WG 
half, the segment of enamel pro- 
jects up in the form of a lit- 
tle crescent-shaped cutting edge, 
as I have endeavored to show 
in the sketch. In its greatest 
length the crown is 1:6 inches; 
and in its greatest breadth 1-2 
inches.

sions of this tooth, and the fact 
of its having been found with the head, (adie it almost cer-

gigantic size. 
2. Fossil Tapir—Previous to the year 1842, no undoubted 
fossil remains of the tapir had been described. Cuvier* describ- 
ed remains resembling those of the tapir family in the structure 
of the teeth; and his Lophiodon seems to have been a closely 
allied genus. In this country, remains have been described re- 
sembling those of the tapir, and have received the name of Ta- 
piroid fossils.+ In 1842 I described and figured{ a tooth found 
in digging a well in the prairies near Opelousas, in this state. 
There could not arise a doubt that this tooth belonged to a tapir. 
Among the fossils brought from Texas by Mr. Huff, there are 
parts of both the upper and lower jaws of the same species as 
that found at Opelousas, and these have enabled me to confirm: 
positively the opinion then advanced, that the tooth described 
was the fifth molar of the left lower jaw.
