Art. I. — On the New Zealand Sword-Fish. By F. J. Knox, L.RC.S.E.

[Read before the Wellington Philosophical Society, June 19, 1869.] 



At a meeting of the Wellington Philosophical Society, held September 15, 

 1868, I communicated a brief notice of the cranium and other portions of a 

 Sword-Fish (Xijihias, Linn.), presented by me to the Museum, which was read, 

 with the supplementary note by Dr. Hector. (See " Trans. N. Z. Institute, 

 Yol. i., page 44.) I now communicate the further details which were then 

 promised. 



The specimen had been stranded on the west coast of the North Island, 

 near Waikanae, in the month of June, 1867. Like most other strangers, this 

 fish attracted immediate attention, and was so cut up that I was only able to 

 procure the preparations now in the Museum, which are insufficient to enable 

 me to determine, with anything like precision, the particular species. From 

 Dr. Glinther's catalogue of the Acanthopterygian fishes in the collection of the 

 British Museum, it appears that there are eight different specimens, divided 

 into two genera : — 



1. Xiphias, ventral fins, none. 



2. Histiophorus, ventral fins, present. 



Now, the portion I procured being only the cranium and anterior part of 

 the dorsal fin, it is impossible to determine even the genus, with anything like 

 scientific precision. In the meantime, I may remark that in Xi]jhias gladius, 

 according to Dr. Giinther, there are "no teeth, neither in the jaws nor on the 

 palate," whilst in the Histiophorus, there are small teeth in the jaws and on the 

 palatine bones ; and it is important to remark that Cuvier (McMurtrie ; s
