Clarke. — O71 New Zealand Galaxidee. 89 



very fleshy, the first rays of vertical ones only being buried in 

 membrane. Base of dorsal shorter than that of anal ; anal 

 higher than dorsal. Extreme length of dorsal and pectoral 

 equal. Caudal is not so much rounded as in G. kokopn. 

 Vertical from origin of dorsal a little posterior to anal orifice. 

 Eibs are tl:iicker in comparison than those of G. kokopu. 



Colour. — Ground-tint pinkish olive-brown, lighter or 

 darker according to class of water. The rearward portion of 

 body only, from about half-way between ventrals and anal, has 

 the sides barred with from 7 to 9 darkish-brown lines, each 

 slightly curved, and thicker along the median line, the apex 

 pointing forwards, the bars diminishing in intensity of colour 

 anteriorly. The rest of the body is unmarked, except a 

 purplish patch bordered with lighter above origin of pectorals. 

 The fins are light-brown, golden-pink in some lights. Iris of 

 eye golden. 



This species is not in full roe until December, and is 

 generally called in Westland the " barred trout." 



Measurements of specimen 6-35 in. in length are ap- 

 pended. 



Galaxias robinsonii. 



Body much elongated and rounded, slightly flattened on 

 back and belly, where the median depressions are well 

 marked. Thickness equalling depth almost to origin of 

 dorsal ; from thence to tail the sides are flattened, and body 

 compressed. The eye is small, and set in a much larger 

 orbit. The cheeks are very fleshy and tumid, the opercular 

 divisions being completely indistinguishable thereby without 

 dissection. Caudal fin is slightly emarginate, the angles of 

 lobes, however, being much rounded. The other fins also are 

 very much rounded, and are excessively fleshy and opaque, 

 the general epidermis covering fully two-thirds of their re- 

 spective free portions. This renders the fin-ray enumeration 

 very diflicult without absolute dissection of each ray of the 

 vertical fins especially. The formulae of dorsal and anal ex- 

 ternally read 9 and 10 rays, but three first of dorsal and anal 

 are very small and fine, completely imbedded in the dark 

 cuticle, and the last rays of same are very fine and close 

 together. The pectorals are placed very low dov/n on ventral 

 surface, and are quite pedunculated ; they originate imme- 

 diately at termination of gill-openings. Two teeth on each 

 side of lower jaws are much enlarged. The maxillaries 

 have their exposed portions very large and tumid as com- 

 pared with other Galaxidee. The anal orifice has a double 

 small papillary appendage. Top of head is wide, but flat- 

 tened portion is short. Eibs much thicker in proportion than 

 ill any other species of this family I am acquainted with.
