37. Ursus floridanus. Florida bear. 
There are present a lower right first molar and a lower right third 
molar which do not appear to differ from the corresponding teeth 
of the existing Florida bear. Possibly better materials might 
reveal differences.

II. DESCRIPTIONS OF CERTAIN SPECIES. 
CHELYDRA SCULPTA HAY. 
Plate 3. Fig. 1. 
From the stratum designated by Sellards as No. 3, there have 
been sent to the writer seven bones of a Chelydra, which is to be 
referred to C. sculpta (8th Ann. Rep. Fla. Geol. Surv., p. 73). It 
is evident that all of these bones belonged to the same individual. 
The nearly complete nuchal and the right and left first costal plates 
are present and the latter fit the nuchal accurately. The second 
left costal joins accurately the costal in front. The fourth and the 
fifth right costals are present, and on the left is the fifth costal, with 
its proximal end missing. 
All of the costals were in life connected with the peripheral 
bones, the jagged suture passing in most cases across the upper sur¬ 
face of the end of the rib. In a specimen of C. serpentina , whose 
warped carapace had been about 240 mm. long the first costal is 
sutured to the peripherals except over the rib. The others, except 
the seventh and eighth and a little of the hinder border of the sec¬ 
ond, are widely removed from the peripherals; and the ribs, whose
