Of this speceies I have only seen casts of the conical vertebrae figured 
by Emmons. The evidence to be deduced from the descriptions and fig- 
ures of this author, is in favor of its reference to the Belodonts, rather 
than to the Dinosauria. 
DIXOSAURIA. 
Clepsysatjrus penns ylvanicus. Lea, Jour. Acad. Xat. Sci. Phil a. IX. 
Emmons’ Geol. X. C., 18GS, in part. 
Teeth of this genus are very rare, one only having been observed by 
Dr. Lea. Prof. Emmons believed that he had discovered two species in 
the Trias of Xorth Carolina, C. Pennsylvanicus and C. leai. The greater 
part of the remains on which these were based I have shown to be Belo- 
donts, bnt one tooth figured by Emmons X. C. Geol. Surv., PI. Y. f. 3, 
may belong to this genus. 
Prof. Kerr’s collection contains two teeth which are identical with that 
associated with the 0 pennsylvanicus by Lea, one. of them nearly perfect, 
the other the basal portion only. They exhibit two minutely denticulated 
cutting edges, separated by one-third of the circumference. This third is 
nearly flat, the remaining portion being very convex. One cutting edge 
extends to the base of the crown, the other occupies only the distal two- 
thirds. The section of the tooth would be round at the base were it not 
for the projection of the cutting edge. The enamel is minutely striats 
under the glass. The base of the larger tooth measures .75 of an inch is 
diameter. The figure of Emmons leaves something to be desired, as he 
does not represent the long cutting edge of the crown. His discriptions 
of the tooth appears to refer to this genus. Kerr’s specimens are conclu- 
sive as to the extent of this formidable genus of carnivorous Dinosauria tp 
X. Carolina. They were obtained in Anson county. 
ZATOMUS Cope. 
This genus embraces reptiles whose teeth are discribed and figured by 
Prof. Emmons, American Geology, Pt. VI. p. 62, fig. 3L He' found them 
associated with radiate osseous plates (probably dermal) which he found on 
•one occasion in connection with the cranium of the supposed Labyrinth©-
