Type specumen.—Based upon a basal section of the left side of the 
rostrum which possesses four serrate molors. Type was formerly in 
the private collection of Grateloup in Bordeaux, France. 
Type locality—Found at a depth of 13 or 14 meters in the quarry 
of Leognan, near Bordeaux, Department of Gironde, France. May- 
encian”™ or Lowermost Middle Miocene. 
Subsequent allocation.—Pedroni did not approve of the derivation 
of the name Squalodon, and proposed to replace it by Delphinoides. 
He redescribes Grateloup’s specimen and applies the specific name 
grateluyr to it. The specific name gratelupi was instituted as a com- 
pliment to Grateloup and as such it should follow the same spelling 
as the name of the person in whose honor it was proposed. Hence 
gratelupi is an obvious misspelling or typographical error and is pre- 
occupied by Squalodon grateloupw of Von Meyer. 
The present uncertainty regarding the identity of the various imper- 
fectly known squalodonts from the Miocene of France and elsewhere 
is largely the result of the description of new forms on specimens 
which do not permit comparison. A summary of what has been pub- 
lished concerning some of these specimens follows. 
In addition to Grateloup’s squalodont, Pedroni discussed two man- 
dibles which he considered referable to Delphinoides gratelupi. Ger- 
vais referred the right mandible,” from the sandstone of Leognan, 
to Champsodelphis macrogenius. This allocation has been questioned,”$ 
for Delphinus macrogenius, as applied by Laurillard, 7 was based upon 
a distal fragment of the combined lower jaws. It consists of a sec- 
tion about 3 inches in length from the symphysial region of the rami 
and possesses three teeth. The type specimen apparently represents 
a Miocene river dolphin. It appears that Laurillard was not the first 
to propose Delphinus macrogenius, as Von Meyer ® used this name in 
the same conection five years previously. The general outlines and 
proportions of the mandible from Leognan recalls certain squalodonts, 
especially Squalodon zitteli and Squalodon calvertensis. The length of 
the symphysis, the proportions of the ramus, especially the width, 
and the large size of the anterior alveolae are features common to all 
three.
