(…) I am enabled to add a new species, through the kindness of Mr. William H. Dall, who has placed at my disposal his notes upon and drawings of two specimens of a peculiar porpoise belonging to the genus, captured off the coast of Alaska in 1873.

The skull, however, was preserved and is now in the possession of the National Museum.
