_ “M. Blainville, who observed a skull of this species in the mu- 
seum of Mr. J. Sowerby, says it had 22 teeth in each jaw, and 
the symphysis 3 the entire length,” Desm. Dict. H. N. ix. 160. 
If this is not a mistake for 4, it will at once separate it from the 
other Stenos, and connect it with Pontoporia. 
__ The skulls named D. rostratus in the Paris Museum are very 
like the Museum specimens of Steno frontatus. The nose is com- 
pressed in front. Teeth 34-24. Length, entire, 214; nose 123, 
_of symphysis of lower jaw 53 ; width at preorbital notch 4 inches.
