1.* Oligorus gigas, Owen. (Cat., p. 1.) 



This fish is no doubt the same as Scicena gadoides of Dr. Solander, Perca 

 prognathus of G. H. Forster, and Polyprion cernuum of Richardson, in 

 Dieffenbach's " New Zealand," IL, 206. By the rule of priority, therefore, 

 it should be called Oligorus gadoides. 



4. Scorpis hectori, Hutton. (Cat., p. 4.) PI. VII. 



A fresh specimen of this fish, caught in the Bay of Plenty, having been 

 brought to the Colonial Museum enables me to correct and add to my former 

 description. 



B. 6 ; D. Jy; A. I j V. I ; P. 17 ; L. lat., 67 ; L. trans., 7/25. 



Teeth on the vomer, palatine bones, and tongue ; cleft of the mouth very 

 oblique; maxillary much expanded and truncated at the end, extending to the 

 vertical from the middle of the eye ; sixth dorsal spine the longest, less than 

 half the length of the head, second anal spine very strong ; scales finely 

 serrated ; caudal forked.

Total length of the specimen, 17;^ inches. 



11. Chilodactylus spiectabilis, Hutton. (Cat., j). 8.) PI. VII. 



A fresh specimen of this fish having been brought to the Colonial Museum, 

 I am enabled to give a better description of it than that in the " Catalogue 

 of New Zealand Fishes," which was drawn up from a specimen that had been 

 preserved in carbolic acid and dried.
