art. 16. TWO SQUALODONTS FROM MARYLAND—KELLOGG. 15 
pl. 8, figs. 12, 12a, and this was first described by Gervais * in 1846.] 
Type in the collection of the “ Faculte des sciences de Montpellier,”’ 
France. 
Type locality.—F rom the “molasse marine” of Saint-Jean-de-V édas, 
a locality west of Montpellier, Department of Herault, France. Hel- 
vetian or Middle Miocene. 
Subsequent allocation.—Gervais states that this molar is three- 
rooted. His illustration shows that the crown of the tooth is imper- 
fect and that the terminal portions of the roots are lost. The 
most characteristic feature of Trirhizodon catulli is the anterior cut- 
ting edge of the molariform teeth, and that portion of the tooth 
figured by Gervais is missing. Otherwise the specimen agrees well 
with Molin’s form, taking into consideration the amount of variation 
to be expected among members of this group, the similarity of the 
steplike arrangement of the cusps on the posterior cutting edge, and 
the fact that the molar is of the three-rooted type. 
SAUROCETUS GIBBESII Agassiz. 
Sauro-cetus gibbesii AGassiz, L., Proc. Acad. Nat. Sci. Philadelphia, vol. 4, pp. 
4-5, 1848. 
Type specimen.—Based upon one imperfect tooth which “ will 
easily be distinguished from the fang of Dorudon, by its great flatness 
and acute serrated edge.” Type in the Museum of Comparative 
Zoology at Harvard College, Cambridge, Massachusetts. 
Type locality.—Presumably from the Ashley River phosphate 
deposits of South Carolina. 
Subsequent allocation.—There is a possibility that future discoveries 
may show the tooth upon which Saurocetus was based to be the 
same as Colophonodon holmesii. In that event this name of Agassiz 
would have priority over that proposed by Leidy.
