8. BERARDIUS ARNUXI, Duvernoy, 
Plate XVI. 
An adult male of the porpoise whale was captured in the entrance to 
Wellington Harbour on 12th January, 1877, and the complete skeleton has 
since been mounted in the museum. 
The condition of the terminal epiphyses of the vertebrae and limb bones 
shows it to be of more mature age than the specimen of slightly larger size 
forwarded to the College of Surgeons Museum by Dr. von Haast, in 1868,* 
which Prof. Flower has made the subject of a most exhaustive and masterly 
memoir.] The external form of this whale is shown in the accompanying 
outline sketch (plate XVI.) which was made by careful measurement. The 
colour was black with a purple hue, except à narrow band along the belly, 
which was grey. The muzzle, flippers, and tail lobes were intensely black. 
The snout was flattened above and the lower jaw projected two inches beyond 
the upper, which was received into firm fleshy lips. The interior of the 
mouth was of a dark slate colour. The teeth did not penetrate the gums, 
nor could their position be discovered till deep incisions were made. 
The blow-hole was on the vertex of the head directly over the eye, with 
arounded protuberance in front. The flippers were stout and rigid, and 
there were no axillary folds of skin to indicate great freedom of motion. 
T'he form of the body was cylindrical and of nearly uniform size between 
the flippers and the vent. The dorsal fin, which commenced over the vent, 
was thick and rigid with a thin rounded edge. The tail lobes were broad 
and powertul.

The skeleton agrees in most of the DESCR Er that Pec by Prof. 
Flower. The teeth are two on each side near the tip of the lower jaw, the 
anterior being the larger, and agreeing in form with the single tooth found on 
each side of the jaw of the specimen captured at the same place in January, 
1870.] The skull of that specimen is in the museum, and agrees in every
