It is thus seen that as indicated by the teeth the tapir found in 
Florida is smaller in size than that which has served as the type of 
T. haysii. In addition the illustration of the type tooth of T. 
haysii apparently indicates a tubercle at the outer side of the tooth, 
blocking in a measure the valley between the transverse ridges. The 
separation of the Florida tapir from T. haysii is based on the differ- 
ence in size together with the observed difference, in structure of the 
lower teeth, including the absence so far as known of the tubercle 
at the. outer side of the cheek teeth of the Florida tapir which appar- 
ently characterizes the larger species. 
The relative measurements of the dental series in this specimen 
from Port Kennedy as compared to Tapirus veroensis is shown in 
the following table of measurements of the two species, the meas- 
urements of the Port Kennedy specimen being those given by Dr. 
Hay (L. C. p. 593). Column 1 is the whole length of the molar- 
premolar series; column 2, the length of the molar series; column 3, 
the premolar series ; column 4, the measurement of the space be- 
tween the canine and the first premolar.

Tapirus haysii calif ornicus, represented by a second lower 
molar, as described and illustrated by Merriam, is a slightly smaller 
tapir than T. haysii, although probably somewhat larger than the 
Florida tapir. This tapir, like T. haysii, has a tubercle at the outer 
side of the lower molar tooth between the base of the anterior and 
posterior ridges. The upper molar described by Merriam from 
Cape Blanco, Oregon, and placed provisionally by him as near to 
T. haysii calif ornicus, presents structural differences in the teeth by
