144 DR. J, E. GRAY ON A NEW DOLPHIN. [May 13, 
from it were taken two foetuses, each 10 inches in length. The adult 
was of a very light lead-colour above and on the sides, gradually 
passing into the dirty leaden white of the lower parts, which were 
covered (as also the flippers) with longitudinally elongated blotches 
of dark lead-colour. 
“ The smaller of the two skulls represents another Porpoise of the 
same species, harpooned off Cape Flattery, on the north-east coast 
of Australia, Oct. 9, 1860. It was considerably smaller than the 
first one, being only 6? feet in length. It was a female. The colour 
was exactly lead-colour, fading into whitish on the lower parts be- 
tween the anus and the snout. The sides were marked with small 
oblong spots of the same colour as the back. Measurements when 
recent :— 
“Total length, snout to centre of tail, 6 feet 9 inches. ; 
* Snout to base of dorsal, 3 feet ; length of anterior border of dorsal 
13 inches; height of dorsal 8 inches; width of dorsal 12 inches ; 
from posterior border of dorsal to tip of tail, 2 feet 8 inches. 
«*Swimming-paws (midway between snout and dorsal) 13 inches 
long, and 53 inches broad ; from their base to end of snout, 13 inches. 
“Tail 22 inches across from tip to tip. 
‘* Anus 2 feet 2 inches in front of tail (centre of tip). 
** Kye 3ths of an inch in diameter, situated 1} inch behind angle of 
mouth, and 12 inches from tip of upper jaw. 
** Lower jaw projecting 1 inch beyond the upper. 
** This Porpoise was occasionally seen, in small droves of from three 
to six, along the north-east coast of Australia, within the reefs. Two 
other species also were seen, but we could not fasten.” 
The two skulls slightly differ in shape and size. 
No. 1 is 17 inches long ; the beak to the notch is 10 inches, and 
the upper teeth-bone 83 inches long; the front lower teeth are worn 
away and truncated, like the teeth of the common Delphinus tursio, 
which was described as D. drunatus by Montague. ‘There are 
twenty-seven teeth on each side in the upper, and twenty-five teeth 
on each side in the lower jaw. 
No. 2 is 17 inches long ; the beak 93, and the upper tooth-bone 
8 inches long. The teeth, twenty-four above (perhaps one on each 
side is deficient, as the end of the jaw is very tender), twenty-three 
or twenty-four below. The front lower teeth are slightly truncated ; 
but this skull chiefly differs from No. 1 in being rather more convex 
and rather narrower, especially in the hinder part, from the middle 
of its length. 
I have compared these skulls with those of the different species of 
Bottlenoses (Z'usio) in the British Museum ; and they are perfectly 
distinct from any of them. The species may be called Delphinus 
catalania. It is smaller in size, and has a much smaller brain- 
cavity than D. eymodice (Gray, Zool. Erebus & Terror, t. 19) and D. 
metis (Gray, Zool. Erebus & Terror, t. 18); and the beak is not so 
tapering as in these species, and the teeth are rather more numerous. 
It is equally distinct from Delphinus eurynome (Gray, Zool. Erebus 
& Terror, t, 17), believed to be from the North Sea.
