236 DELPHINID-E, 



as the Steno attenuatus, but the Museum copy of Schreber does not 

 contain the plate referred to. 



There is a skull in the Museum of the Asiatic Society of Calcutta 

 which seems to be that of Steno attemiatus, being probably that 

 mentioned as " a Dolphin found near the Isle of France " (Asiatic 

 Besearches, xii. App. xxvii.). Lower jaw 14 inches. Teeth |-j-. 

 And another lower jaw, "from the high seas," with series of 38 

 teeth, presented by Mr. C. Harvey (Journ. As. Soc. x. 737). Also 

 two skulls, toothless, wanting the lower jaw, with series of 39 teeth- 

 sockets. Length 15 and 15|^ inches. All these would appear to be 

 the same. — Blyih, I. c. 



A left ramus of the lower jaw with series of 43 teeth, in the 

 same museum, is vertically much deeper at the symphysis, and un- 

 doubtedly appertains to a distinct species. — Blyth. 



Captain Jethro Fairweather presented to the Museum of the 

 Asiatic Society of Calcutta a skull of a small but not young Steno, 

 which seems to be St. attenuatus, Gray. It was procm'cd not far 

 from the Sand-heads, out of an innumerable herd of them, " as far 

 as the eye could reach in all directions," and was of a palish lead- 

 colour. Not therefore, however, the DelpMnus MaJayanus, yar.phim- 

 beus, which is a much larger species common in the bay. Teeth

Major E. C. Tyler has also sent to the same museum a skull taken 

 west of the Cape of Good Hope, which agrees, or very nearly so, 

 with the two heads minus the teeth, and the lower jaw, mentioned 

 before. — Blyth.

 front of the line of the notch. Teeth ^^, slender, conical. Lower
