248 ’ Fossil Bones from Tennessee and Texas. 
The following figures represent the specimens from Texas. . 
Fig. 3 represents the left half of the lower jaw, nearly com- 
plete. A portion of the posterior margin of the ascending branch 
is broken off; the condyle is broken off, but the process in part 
remains; the posterior molar is wanting ; the third molar is. with 
Fig. 3—one third the natural size.

the jaw, but is loose, and being a deciduous tooth, was taken off 
in making the drawing, to show a young tooth which is growing 
_ up under it to replace it. There is a canine tooth on each side. 
Of the incisive teeth none remain, and the sockets of only the 
four middle ones can be seen, though it is probable that the 
two small lateral ones were present. The total number then 
would be six molars, one canine, and three incisive teeth on each 
side, making a total of twenty. 
The presence of the canine teeth, the full number and replace- 
ment of the molars,. show that the animal was just attaiming to 
the adult age. All of the molars are considerably worn except 
ing the posterior one. "That lying over the new one which was 
growing up, was very much worn. 3 
The proportions and size of this jaw agree perfectly with those 
of the American tapir, as is shown by the following comparison 
between the measurements in the American, the present fossil, 
and the Indian tapir. 'The measurements are in inches and tenths 
of an inch. The measurements of the American and Sumatra 
tapirs are from Cuvier.*
