 The only difference which I can observe between the fishes from 

 the Atlantic and Pacific Oceans, is the apparently smaller size of the 

 scales. However, as oui' New Zealand specimen is not in a good 

 state of preservation, even this is a doubtful character. Thus, for 

 the present, we can only contirm Forster's observation as regards 

 the occurrence of this genus in New Zealand.

4. Scombresox aequirostrum. 



Scomberesox equirostrum, Lesueur, Journ, Acad. Hat. Sc. Philad. ii. 

 p. 132; Cuv. Sf Val. xviii. p. 479. 



Both jaws of equal length. 



From Chile. 



Lesueur describes a stuffed specimen preserved in a collection at 

 Boston, without mentioning the locaHty where it had been obtained. 

 It is probable that this specimen was caught on the coast of the 

 United States, and not less so that it was merely a Be. saurns deformed 

 by stuffing. If this is really the case, the Chilean fish described by 

 Valenciennes may prove to be a distinct species.
