saurus. The family would be distinguished by the peculiar arrangement of the 
bones of the paddles, and the reduction of the number of intercentra. 
The classification of the genus Baptanodon would then be best expressed by the 
following : 
Class, Reptilia; Order, Ichthyosauria; Family, Baptanodontids ; Genus, Bap- 
tanodon.
