VERTEBRATES FROM MIOCENE, PLIOCENE AND PLEISTOCENE. I I I 
Survey. In this paper the Florida Mastodon is described as Mastodon ( Tri- 
lophodon) floridanus, and measurements of the teeth are given. The tusk is 
noted as having a band of enamel. The llama remains are distinguished as 
Auchenia major, minor and minimus, measurements of the astraguli being given 
for each. The presence in the collection of the astralagus of a Megatherium is 
also noted.

An Extinct Boar from Florida. Acad. Nat. Sci. Phila, Proc., 
PP- 37 - 38 , 1886. 
In this communication Dr. Leidy establishes a new genus and species, 
Eusyodon maximus, based on a tusk resembling that of a hog. The locality 
from which the specimen was obtained is not given, altho the context shows 
that it came from near Archer, Florida. The specimen which was figured, was 
subsequently recognized as the lower tusk of a rhinoceros.

Fossil Bones from Florida. Acad. Nat. Sci. Phila. Proc., pp. 
309-310, 1887. 
In this communication Professor Leidy acknowledges receipt of two barrels 
and three boxes of fossil bones from Florida submitted by the United States 
Geological Survey. The collection was made by L. C. Johnson from Mixon’s 
bone-bed ten miles east of Archer (near Williston). Hippotherium plicatile is 
described in this paper and is based on an upper molar which is figured. Meas¬ 
urements are also given. The genus and species Eusyodon maximus estab¬ 
lished in a preceding paper, is here recognized as an error, being based upon the 
lower tusk of a rhinoceros.
