not quite reaching the anterior margin of the eye. There are 

 about seventy-seven rows of scales above the lateral line between 

 the suprascapular and the hypural, but its tubules are widely 

 spaced anteriorly, there being only about fifty-nine between the 

 same points. 



Co^owr. — Olive-green above, silvery below; the back and sides 

 are closely mottled with irregular, anastomosing, darker bands, 

 which tend to become longitudinal posteriorly. The dorsal and 

 caudal have faint indications of darker markings, the other fins 

 colourless. Eye pale golden, cheeks silvery. 



Described and figured from a single small example, 95mm. 

 long. It differs from the adult fish figured by Stead in having 

 the body elongate instead of deep, the snout convex instead of 

 pointed, and in its colour-marking. The eye is also much larger, 

 and the proportions generally are very different, but an examin- 

 ation of the material available convinces me that all these 

 features are merely juvenile characters. 



I am indebted to Mr. H. K. Anderson for the opportunity of 

 describing and figuring this specimen, which he collected in the 

 Murrumbidgee River below the Berumbed Weir, on November 

 13th, 1914.
