have attributed the name to Keferstein (1834), who, however, cites 
it without reference as a synonym of D. longirostris, a name applied 
to a living species of Prodelphinus by Gray in 1828, and to a species 
of Delphinus by Dussumier in 1829. In 1846, Laurillard, evidently 
supposing that the fossil required a new specific designation formally 
bestowed the name Delphinus renovi upon it after the original discover- 
er, and it is so figured in three views by Van Beneden and Gervais in 
the Osteographie. Finally, Longhi in 1898, referred it to the genus 
Champsodelphis. As may be gathered from the figure (Text-fig. 1), it 
agrees with the Florida species in the strongly convex outline of the 
base of the maxilla. In both, the proximal end of the tooth row makes

an outward bend at this point, but in the French specimen the row 
of alveoli ends about opposite the summit of the convexity, whereas 
in the Florida species it ends in advance of this point. Moreover, 
the alveoli themselves seem much larger in the former and doubtless 
supported functional teeth. A more important point is indicated in 
the figure by the presence of three shallow depressions near the middle 
of the length, internal to the alveolar row, for the reception of the 
points of the corresponding mandibular teeth. This detail, perhaps 
not fully brought out by the artist, shov/s that the lower tooth row 
closed within the upper, at least proximally, and, taken in connec- 
tion with the similarity of the maxillary outline, seems to indicate at 
least a generic affinity v/ith Pomatodelphis.
