64 FLORIDA GEOLOGICAL SURVEY TENTH ANNUAL REPORT. 
RELATIONSHIP TO OTHER PLEISTOCENE SPECIES. 
Two species, as already noted, have been recognized in the 
Pleistocene of North America. These are Tapirus haysii and a 
smaller species commonly referred to the recent Tapirus ferrestris. 
The type specimen of Tapirus haysii is a lower molar, probably the 
second, obtained from Big Bone Lick in Kentucky. This tooth is 
illustrated in Holmes Post Pliocene Fossils of South Carolina, pi. 
17, figs. 7 and 8, i860. It is preserved in the Philadelphia Acad- 
emy of Sciences. According to Leidy this tooth measures 12JA by 
IO /4 lines or 26 by 21.3 mm. It is, therefore, a tooth from a large 
tapir. In addition Leidy referred to this species a part of a lower 
jaw from Mississippi and a lower molar tooth from Indiana, all rep- 
resenting a large species of tapir. Among other specimens subse- 
quently referred to Tapirus haysii, the best preserved includes most 
of the upper and lower jaws from the Port Kennedy cave in Penn- 
sylvania. 
The Florida fossils represent a smaller tapir than those which 
have been referred to Tapirus haysii. This is indicated by the 
comparative measurements of the teeth, both of the lower molars 
as indicated by the type specimen of Tapirus haysii, and the upper 
molars are taken from specimens subsequently referred to that 
species. These measurements are given in the following tables :
