1. _Inland Waterway Canal, Carteret County._—In the collection of the
State Museum, at Raleigh, the writer has seen an upper hindermost molar
(A. N. 1326) which certainly belongs to this species and which is said
to have been dredged up in Core Creek. The creek forms a part of the
Inland Waterway which joins Neuse River with the harbor at Beaufort. The
molar was presented to the State collection by Mr. H. T. Paterson, U. S.
assistant engineer, now of Newbern, North Carolina. From the director of
the museum, Professor H. H. Brimley, the writer has received photographs
of this fine tooth. In the same canal was found a jaw of a mastodon
which is mentioned on page 117. From Mr. Paterson the writer has
received the important information that the tooth was found in Core
Creek about 8.5 miles from Beaufort, in 1909, while dredging a
sedimentary deposit varying from 6 to 8 feet in depth, containing
numerous cypress stumps and roots and underlain by a deposit of sand
mixed with shells and other fossils. Into this the dredge went from 6 to
8 feet.
The tooth is worn to the base in front and a very few plates are
probably missing. Nevertheless, there are still 22 or 23 remaining. The
base of the tooth is nearly straight and the ridge-plates are but little
curved. The length of the base is 232 mm. Measured along the side of the
tooth are 11 ridge-plates in a 100–mm. line. The enamel is unusually
thin, being about 1.3 mm. in thickness, and but little undulating across
the grinding-surface.
It is believed that the deposit containing this elephant tooth and the
cypress stumps belongs to the first interglacial, while the underlying
sands containing marine fossils belong to the Nebraskan glacial stage.

1. _Palma Sola, Manatee County._—Mr. Charles T. Earle, an enthusiastic
collector living at this place, sent to the U. S. National Museum in
1921 various lots of vertebrate fossils which had been washed up on the
beach at Palma Sola. Among the fossils belonging to the Pleistocene is a
tooth, a right lower second milk molar, which must apparently be
referred to _Elephas primigenius_. It is much worn, the plates present
rising above the base only about 10 mm. The anterior root and the
posterior had been considerably absorbed. Only 4 ridge-plates remain;
evidently at least 1 had wholly disappeared from the front, and 2,
possibly 3, from the rear. The original length of the tooth can not be
determined. The width is 30 mm. The 4 enamel plates present, together
with the portion of cement belonging to each, occupy a length of 30 mm.
The enamel is thin.
