Art. XVI.—List of Seals, Whales, and Dolphins of New Zealand.

[Read before the Wellington Philosophical Society, 6th August, 1873.]

The fauna of New Zealand, as regards marine mammalia, is extending, and I have no doubt will be found to be much richer as they become more studied. For example, we have not yet had the “Sulphur Bottom” or the “Trigger” of New Zealand whales, and there are other species mentioned as found in those seas, but in such a manner as not to be able to be entered in scientific catalogues. There are many more species recorded as inhabiting Australian seas, which, no doubt, range as far as New Zealand, but I have only inserted these on the authority of specimens,

Habitat—Cook Strait, Titai Bay (Knox).

Length, 9 feet. The lower jaw is narrow in front, gradually becoming wider behind, and with a distinct gonyx at the end of the symphysis.

The lower jaws of the two Ziphioid whales figured by Dr. Hector have only a tooth at the front end, instead of a tooth at the front and one a little further behind on the side of the jaw, as is usual in Berardius. Perhaps this depends on age. The having only two teeth quite in front of the lower jaw is the character of Epiodon, but that has a sub-cylindrical tooth, and Dr. Hector's animals both have compressed triangular teeth like Berardius, as figured in his plates, so that if they are not Berardius they are a new genus.

Mesoplodon longirostris, of Krefft, of a skeleton of which in the Australian Museum of Sydney he sent me a very beautiful photograph, appears to be either Berardius hectorii or a new species. The photograph does not show any teeth. The beak of the Australian specimen appears to be longer, viz., nearly twice as long as the head, whereas the beak figured by Hector is but little more than one-and-a-half times as long as the head.
