The second and larger specimen (B) is 18 in. long, and far brighter 

 coloured than the first. Head above and back dark olive green, which is also 

 the colour of the lateral line ; middle portions of cheeks and side white ; 

 throat and atldomen pink ; anal fin pink ; pectoral fin above dark olive, centre 

 white, below pink, corresponding to position of colours of the body ; dorsal fin 

 white, with dark olive green rays and fringe ; caudal above and below dark 

 olive green, centre white, fringed below with pink. 



Besides in the colour there are some minor points of difference between 

 the two specimens, such as form of the operculum, so that possibly they might 

 represent two distinct species, in which case I would propose for the latter the 

 name of Leptoscopus tricolor. 



NOTOTHENIA MAOEIENSIS.* Sp. nOV. 



Maori Chief. 

 D. 3/29; A. 23; Y. 6; L. lat. 58. 



Length of the head one-fourth of tlie total, of which the height of the body 

 is one-sfxth ; total length 1 7 in. ; eyes slightly directed upwards ; the upper 

 surface of head is flat and granulated ; suborbital space, upper portion of 

 pneoperculum and operculum covered with scales, the two latter naked below. 

 The lateral line stops in a vertical line with the root of the last dorsal spine, 

 whilst its lower continuation begins again under the twenty-sixth doi^sal spine, 

 so that the latter overlaps the upper One. 



The whole rays of the pectorals are branched ; colour black, with the 

 exception of the abdomen, which is light grey, the sides shading oflF gradually 

 into that colour ; rays black ; membrane brownish grey. 



Caught near Lyttelton harbour, where, according to the fisherman who 

 brought it, it is very seldom seen. The dark colour and the peculiar 

 expression of the face has given rise to the popular name of Maori Chief, 

 wbich has suggested to me the proposed specific designation.

Eyes on the right side, the lower rather in advance; mouth unsymmetrical, 

 narrower on the right side than on the left, the length of the left maxillary 

 being one-fourth of that of the head ; teeth villiform on the blind side only 

 where they form bands ; dorsal and anal rays entii'e, with the exception of the 

 few largest ones, which are slightly divided ; dorsal and anal fins scaleless ;
