Lower jaw with distinct lateral canines. Depth of bod}' 

 4-5-|- in the length, length of head 4-5. Snovit as long as 

 or a little longer than eye, the diameter of which is 4-5 

 in the length of head, interorbital width 1|— 2|-. Jaws equal 

 anteriorly ; maxillary extending to below posterior part of eye. 

 8 or 9 bi'anchiostegals. 10 or 11 gill-rakers on the lower part of 

 the anterior arch. Dorsal lY 7-9 ; distance from origin of dorsal 

 to base of cavidal 3-|—4|- in the length of the fish. Anal IV-V 

 10-11, commencing below or a little behind the origin of dorsal, 

 when laid back extending to or a little beyond the base of the 

 caudal. Pectoral extending from more than | to nearly ^ of the 

 distance from its base to the base of ventral. Ventrals 7-rayed, 

 originating at a point equidistant from snout or eye and base of 

 caudal or from anterior part or middle of pectoral and oi-igin of 

 anal, extending |— | of the distance from their base to the origin 

 of anal. Caudal truncate. Caudal peduncle from -| to as long as 

 deep. Brownish, with narrow light vertical stripes, which may 

 be undulating or irregular or may form reticulations ; often a light 

 vertical bar above the base of pectoral, succeeded by a dark purplish 

 blotch. 



New Zealand and neighbouring islands. 



A large female specimen, ready to spaAvn, measui-ing 265 mm. 

 in total length, has not been included in the above diagnosis. 

 The depth of the body is |- of its length, the caudal peduncle is -I 

 as long as deep, the maxillary does not extend beyond the middle 

 of the eye, the origin of the anal fin is only a little in advance 

 of the middle of the dorsal. These peculiarities appear due 

 partly to the condition of the fish, partly to individual variation.
