eleven rays ; the caudal is emarginate, of sixteen rays ; the anal 

 is a little behind the dorsal, and has fourteen rays ; the ventrals 

 are inserted a little nearer to the anal than to the pectorals ; they 

 are rather large, and formed of seven rays ; the pectorals are 

 rather shorter than the ventrals, but longer than the distance from 

 the posterior margin of the eye to the extremity of the operculum. 

 The lower teeth are a little longer than the upper ; on the tongue 

 there are are three or four large teeth in front, and a line on each 

 side further backwards. 



Of a light green colour, with the belly white ; the head is 

 purple ; all along the body are numerous, minute, black points, 

 disposed in transverse clusters. The fins are white ; sometimes 

 there is a transverse green blotch on the middle of the dorsal ; 

 base of the anal of the same colour ; caudal, is green ; the eye, 

 silvery. 



Very common in the lower Tarra ; it attains 7 and 8 inches in 

 length. 



The specimens preserved in liquor, take a general brown 

 appearance. 



Nota. — I have given here the number of fin rays that I have 

 usually found ; but they seem to be subject to great varia- 

 tion, as in some specimens absolutely similar I find — D. 10. 

 A. 15. In one, the number of the dorsal rays is much less still, 

 (7) ; but I am not certain that it is entire. 



GALAXIAS CYLINDEICUS. 



Very nearly allied to Attenuatus, but still longer. The height 

 of the body is contained ten and a-half times in the total length ; 

 the head is seven and a-quarter times in the same ; the eye is 

 four and a-half times in the length of the head. The lower jaw 

 is rather longer than the other. The body is long and cylin- 

 drical. The dorsal is formed of ten rays — the first very short ; 

 the anal of from twelve to fourteen, the first of which is very 

 short ; the caudal is emarginated, of eighteen or nineteen long 

 rays ; the ventrals of seven rays ; they are placed at an equal dis- 

 tance from the end of the mandibula to the base of the anal. Six 

 very large hooked teeth on the front part of the tongue, and 

 others, on each side, backwards.
