The Pleistocene of North America: and its vertebrated animals from the states east of the Mississippi River and from the Canadian provinces east of longitude 95°

1. _Neals, Alachua County._—Through the kindness of Dr. E. H. Sellards,
State geologist of Florida, the writer has been permitted to examine
various teeth (No. 1186, Florida Geological Survey) taken from the T. A.
Thompson phosphate mines at Neals. Among these is a lower left milk
molar of a tapir. The length of the crown is 21 mm., the width at the
front lobe 14 mm., at the hinder lobe 12.5 mm. The buttresses are well
developed. The tooth may be provisionally referred to _Tapirus
terrestris_, yet living in Brazil. Although this tooth was found in
phosphate materials, it seemed to Dr. Sellards more probable that it was
an intrusion from Pleistocene deposits. The present writer refers the
Alachua clays to the Nebraskan stage of the Pleistocene. Sellards has
referred to this tooth in his Eighth Annual Report, 1916, p. 94.
2. _Archer, Alachua County._—In 1884 (Proc. Acad. Nat. Sci. Phila.,
1884, p. 119), Leidy briefly described a tooth of a tapir found by Dr.
J. C. Neal, of Archer, Florida. This is now in the U. S. National
Museum, No. 3329. The tooth is the third premolar of the left side,
implanted in a fragment of maxilla. The crown is 23 mm. long and 27 mm.
wide. Leidy stated that it differed neither in form nor size from the
corresponding tooth of the living _Tapirus americanus_ (_T.
terrestris_); but in a specimen of this the corresponding tooth is only
18.5 mm. long and 25 mm. wide. The fossil agrees in size with the same
tooth of _T. haysii_ from the Port Kennedy Cave in Pennsylvania (Hay,
Geol. Surv. Indiana, vol. XXIII, p. 593). With this tooth had been found
teeth of a young mastodon, remains of several individuals of a species
of rhinoceros, some foot-bones of a llama, a calcaneum which Leidy
thought possibly belonged to the extinct _Cervus americanus_ (_Cervalces
scotti_), and vertebral centra of a small crocodile. The cervalces was
afterwards dropped from the lists. These remains had been found in a bed
of clay, occupying a ridge in a pine forest. The deposits are now known
as the Alachua clays, and they, as well as the contained fossils, will
be discussed on page 375. The tapir remains are not included in Leidy’s
list given in Bulletin 84 of the U. S. Geological Survey.
