A dental plate of Aeiobatis is referred in error to Myliobaiis 
dixoni by F. Noetling, Abh. Geol. Specialk. Preuss. etc. vol. vi. pt. 3 
(1885), p. 2/, pi. ii. fig. 3. Vertebrm from the Samland Eocene 
are also doubtfully associated with this genus by Noetling, tom. eit. 
p. 29, pi. viii. figs. 3-5. 
^ ertebne supposed to be referable to Aeiobatis are described by 
C. Hasse (Natiirl. Syst. Elasm., Besond. Theil, p. 157), from the 
Cretaceous and Tertiaries of the Continent. 
The genus and species Mesobatis eximius, Leidy’, have been 
founded upon a jiortion of the dentition from the Ashley River Phos- 
phate Beds, South Carolina, differing only from Aeiobatis in the 
presence of a row of minute lateral teeth, occupying the interspaces 
of the bevelled ends of the broad teeth. 
A dermal tubercle from the Phosphate Beds of South Carolina 
is assigned to Ceratoptera (Miiller and Henlc) under the name of 
C. unios, J. Leidy, Journ. Acad. Nat. Sci. Philad. [2] vol. viii.
