was but twice taken during the ‘‘Nora Niven’’ expedition, 
though each haul was fairly rich in individuals. 
Our first two hauls, after rounding Cape Runaway, in the 
Bay of Plenty were practically continuous and produced this 
fish in depths ranging from 66 to 105 fathoms. 
Some characters of this species were discussed in my report 
of the Fishes of the ‘‘Thetis’?’ Expedition (vide supra) and 
need not be repeated here, the number of caudal rays there 
printed as 9 should have been 19. The word Chlorophthalmus, 
also, is misspelled. 
The only species ascribed to this genus previously taken in 
New Zealand is C. gracilis Giinther,? which however differs 
so greatly from typical forms as to be quite unmistakable, and 
which indeed I would regard as a separate genus ........ 
differing from Chlorophthalmus by its elongate body, smaller 
eye, long maxillary, and the forward position of the ventral 
fins.*
