The first dorsal fin arises within the vertical of the opercular margin, and the 

 middle spines are longest; the fins are subcontinuous. 



Scales: Cheeks, opevcles, and body scaly, the scales small; the lateral line 

 passes almost straight from above the opercle, near to the dorsal edge, to beneath 

 the middle of the soft dorsal. Beneath the base of the v-vi dorsal spines it sends 

 off a downward Vjranch which descends suddenly to the mid-line of the body, 

 thence straight to beneath the origin of the soft dorsal, and terminates in advance 

 of the middle caudal rays. 



Colours: Iridescent blue above, silvery beneath; a deep black blotch on the 

 dorsal between the i-iii spines, the fin narrowly edged witn black : soft dorsal, 

 anal, and caudal orange. 



Length, to 711 mm. 



This species has lieen entered in the New Zealand lists is I'linntthiclitli ii.<

B., vii : 1)., ho; A.. BO; V.. dex. 7. sin. 4; P., dex. 11. sin. 12; C. 14 + 4: 

 scales, .S2. 



Rostral flap very long, extending downwards below the level of the maxilla, 

 mouth large, a broad band of teeth in each jaw on the blind or left side only. 

 Eyes on the same level : interorbital space equal to the longitudinal diameter of 

 the eye. 



The dorsal rays commence at the tip of the rostral flap, the first five or six 

 are free : the dorsal and anal are coterminal, close to the outer caudal rays : the 

 right ventral is very long and connected with the anal, last ray of left ventral 

 opposite to the vent. 



Scales: Strongly ctenoid on the right, smooth on the left si(h'. No scales on 

 the fin rays, the caudal excepted. 



Colours: Warm brown above, reddish towards the margins, irregularly blotched 

 with dark brown; under-side colourless or more or less blotched. 



Length, 482 mm. 



This species differs from A. i(i.-<frafii.'<. with which it appears to have been con- 

 founded, by the scaleless dorsal and anal fins, the smooth character of the scales 

 on the left side, and the wider interoibital space. 



Pelotretis gen. nov. 



Family Pleuro/ieifidae. Eyes on the lighl side, the lower advanced. Mouth 

 small, subsymmetrical ; teeth on the blind side only, no vomerine or palatine 

 teeth. The dorsal commences behind the snout, and is not connected with the 

 caudal. Two ventrals, the right one in the same line and lontiniious with the 

 anal. Scales moderate, ctenoid on the right side ; lateral line nearly straight. 

 Gill-openings narrow, the membranes broadly united beneatli the throat: gill- 

 rakers short and conical. 



This genus differs from A//ii/i<>fnfi.--- by the small subsymmetrical mouth, the 

 large eyes, the upper of which is close to the profile, the b;ick\vard origin of the 

 dorsal ftn, and the absence of any lostral prolongation.

 scales, 78 . 



Length of head, 4'S : height of l)o(l_\-. l.S : length of caudal. ")() in the length: 

 diameter of eye, 3'9 in the the heafl. 



The eyes are large, crowded to the front of the head, and the upper one is 

 close to the dorsal edge, which is incised so that the eye can be seen from the 

 under-side; lower eye slightly advanced, separated from the maxilla by a narrow 

 ridge only. 



The dorsal fin begins aV)ov(' the front edge of the eye. and none of the rays is 

 entirely free ; the longest are 2'2 in the head. 



Scales: Imbricate, ctenoid on the right side, smooth but striated on the left. 

 Head, body, and fin-rays (ventrals and antei'ior rays of the dorsal and anal 

 excepted) covered with scales. 



Colours: Grey or brown above; both body and fins with inegular though well- 

 defined markings, sometimes absent : under-side yellow. 



Length, 311 mm. 



This is the common "lemon sol(>" of tlu; colonists, and does not appear to 

 have been previously diagnosed, the n-nne having been erroneotisly associated with 

 A mmofrefis rosfraftis.
