" 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 f the entire length," Desm. Diet. H. N. ix. 160. 

 If this is not a mistake for f, 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 f i~f T- Length, entire, 21 J ; nose 12, 

 of symphysis of lower jaw 5^ ; width at preorbital notch 4 inches.
