Plate 8 , figs. 1-2. 
In the collection of the Florida Geological Survey are five 
lower teeth which seem to belong to- the genus Parahippus. No. 
1634 is a right molar with a part of the front end missing and with 
a long hinder root; No. 1635, the anterior end of a right molar; 
No. 1636, the crown of a left molar; No. 1637, the crown of a 
left molar; No. 1638, the crown of another left molar. These 
teeth were all found at Newberry, Alachua county, Florida, and 
were presented by the Franklin Phosphate Company. 
The following table presents the measurements of some of 
these teeth. 
Measurements of lower teeth of Parahippus sp. indet., in millimeters.

inasmuch as the width of the front lobe is 12 mm. 
In these teeth there is an internal cingulum which continues
