SUBANTARCTIC ISLANDS OF NEW ZEALAND.

The head is not markedly broad, its width being equal to its depth ; it is smooth 

 and naked, with the exception of the upper part of the cheeks and opercles, which 

 bear small imbedded scales. The upper lateral line arises close behind the opercle, 

 rises slightly, and then runs almost straight to beneath the last dorsal ray ; the 

 lower line occupies the middle of the caudal peduncle, arising posterior to the middle 

 of the anal. 



Teeth. — A row of widely spaced canines stand in front of each jaw ; behind 

 these a band of villiform teeth, broad in front and narrow at the sides ; no teeth 

 on the vomer, palatines, or tongue. 



Fins. — The dorsal commences slightly behind the opercle ; its second spine is 

 the longest, 3-9 in the length of the head ; the outline of the fin is rounded, and the 

 length of its base is twice the diameter of the eye, that of the second dorsal 2-3 in 

 the total. The anal arises beneath the sixth dorsal ray, and extends further back 

 than the dorsal ; the pectoral is feebly rounded, and does not reach to the vent ; 

 the ventral extends to the middle of the pectoral rays, and is equal to the caudal 

 in length, or one-half that of the head. The caudal is slightly forked, and the 

 depth of the peduncle is one-half longer than the diameter of the eye. 



Colours. — Olive above and pale yellow beneath ; fins dark brown, the median 

 ones margined with pale yellow.
