I have not been able to find the skull of this animal, which was 
in Mr. Sowerby’s Museum in Mead Place, Lambeth. 
The figures of the skull in Cuvier and Schlegel show it is a Steno. 
The skull in Paris is very like Steno frontatus of India.

According to O. Fabricius, it is not uncommon as far north as 
Greenland. 
«They come on the Cornish coast in considerable numbers, more 
especially when the Pilchards and Mackerel abound ; and not unfre- 
quently are taken in the drift-nets, in the meshes of which they be- 
come entangled by the teeth. In the month of September 1845, 
eight or ten in a day were brought on shore in Mount’s Bay for 
many days in succession.’ — Couch, Cornish Whales, p. 39.
