Jaws moderately produced ; the lower longer than the upper : teeth rather more than twenty on each side above and below ; straight, with obtuse summits.

D. Tursio, Desm. Mammal, p. 514. Mem. Brit. An. p. 37. D. trun-catus, Mont, in Wern. Mem. vol. III. p. 75. pi. 3. Bottle-nose Whale, Hunter in Phil. Trans, for 1787. pi. 18.


Entire length eleven feet: girth seven feet four inches: length of the mouth fourteen inches; from the snout to the eye sixteen inches; from the same to the pectoral fin two feet; from the same to the dorsal four feet eight inches ; from the same to the vent seven feet three inches; length of the dorsal twenty-three inches; height of the same ten inches.


Larger than the last species: lower jaw projecting further beyond the upper: teeth less numerous, (21-21)/(21-21) to (23-23)/(23-23) = 84 to 92, straight, somewhat conical, but blunt and truncated at the extremity.

But little known as a British species. Hunter's specimen was caught upon the sea-coast near Berkeley, and is now in the Museum of the College of Surgeons. In the same collection is a second individual from the Thames. The one described by Montagu, which appears to have been large and aged, with the summits of the teeth more than usually truncated, was taken in the river Dart, in 1814. The measurements given above are those of a fourth individual which occurred a few years since in the river at Preston. They were obligingly sent me by Mr Gilbertson of that place.
