middle of tail, 1 foot; at 8 inches from tail, 6 inches. Girth of 
head at blow-hole 2 feet 64 inches. Tip of snout to blow-hole 
1 foot 1} inch. Length of beak 2} inches. Height of dorsal 
fin 9 inches. These measurements were from a male. There is 
a dark mark around the eye, about # of an inch broad: The 
eye is small, and the form of the pupil is crescentic, with the 
points upwards. The blow-hole is situated between the eyes ; 
its form is crescentic, the concave side being forward, and there 
is a slight depression around the blow-hole. An auditory meatus 
is present (not to be found in several) above and rather behind 
the eye, and over the anterior portion of the pectoral fin. Its 
opening would admit a No.1 shot. The head is sharp and 
beaked ; the lower jaw a little longer than the upper. The 
number of teeth is 2 2; they are largest in the middle of 
the jaw, and gradually diminish in size towards each end, those 
at the anterior extremities of each jaw being the smallest. 
There are no teeth at the symphysis of either jaw for the space 
of nearly an inch. In form they are conical, being slightly in- 
curved at the back, and nearly straight in front; those in the 
lower jaw are most incurved. While the teeth in the upper 
jaw point forwards, those in the lower jaw point backwards; 
so that when the mouth is shut, they lock ito each other very 
closely, and the points of the teeth are lodged in little fosse 
in both jaws: these fosse appear to be only in the mem- 
brane of the gum. The palate is smooth and spotted. The 
tongue is not free, but, the frenum being large, it admits of 
great movement; it is black at the centre, and white at the 
margins. At the symphysis of the lower jaw the lip turns up- 
wards, and has two slight elevations, which fit into two corre- 
sponding notches in the upper lip. There is a regular pro- 
labium in the upper lip, so as to give it a pointed appearance. 
The colour of the back is jet black. There is a long streak to- 
wards the tail, of a dirty yellowish colour. About the middle of 
each side there is a very conspicuous obloug white streak, under 
which the sides are dusky. The belly is of a beautiful clear 
white. The pectoral and dorsal fins are black. The tail is black, 
with a very little white underneath. 
From this animal being shortly but decidedly beaked, I as- 
sume that it belongs to the genus De/phinus ; but I can find no 
description of a species in the works of Bell, Fleming, and Jar- 
dine which agrees with it. It seems to come nearer to the de- 
scription of the Delphinus Tursio of Fabricius than to any other ; 
but I have no doubt it will be found to be different. The sym- 
metry of its form, and more particularly the great beauty of the 
colours, when contrasted with each other, with the streaks and
