described as having the teeth 2%, whereas our dolphin has teeth $4. 
Moreover, the dorsal fin in the Cape species is stated to be triangular, 
while in ours it is rounded as shown in my original sketch. This feature 
has been confirmed by Van Beneden, who has founded a new species under 
the name of Electra hectori (Bull. Acad. Roy. de Belgique, 1881) on a very 
complete specimen presented to him by Dr. Finsch, who obtained it on the 
north-east coast of New Zealand. 
The only discernible difference in the description of the two animals is 
that the nose and forehead were white in my specimen, and black in Dr. 
Finsch’s, a character of small importance where all the other colouration is 
the same. According to Professor Flower, Electra clancula is only founded 
on a skull, and this skull, although agreeing in other respects, differs so 
materially in the form of its pterygoid—a character which Gray does not 
allude to—from our species that he places it almost in the same species 
as the Cape dolphin, distinguished by the specific name conferred by Van 
Beneden. The statement which I made in the first notes of this dolphin, 
to the effect that the ‘‘cervical vertebre’’ are anchylosed, should probably 
have been “anterior cervical vertebrz," and I have to thank Professor 
Flower for pointing out the error; but, unfortunately, until new specimens 
have been obtained and prepared, the complete osteology cannot be com- 
pared, as both the complete skeletons which I recorded as being in the 
Museum have been given away, one to the ** Challenger" Expedition, and 
the other to the British Museum, under the impression that there was a 
third complete specimen in store. This latter has been recently cleaned, 
and proves to be altogether a different species, but one with which, as 
already stated, the present dolphin is often confounded.

D. nove-zealandie, Q. and G. ; Hutton, Trans. N.Z. Inst., ix., 349. 
Comparison of these types with a large number of specimens from these 
seas has enabled Professor Flower definitely to determine that the above 
species are in every character identical, thus adding another to the list of 
Cetaceans that have a world-wide geographical range. In the Museum 
there is a fairly complete skeleton of this species, and a number of skulls 
and lower jaws. 
9. T'ursiops tursio, Buonaterre. 
Tursio metis, Gray ; Hector, Trans. N.Z. Inst., v., 162. 
These species are now considered to be closely allied, if not identieal. A 
comparison of a complete skeleton in the Museum with the descriptions and 
anatomical drawings of the northern species does not afford any ground for 
keeping them as distinct species.
