Upper parts greyish-blue with green tinges on the body, and 



brown on the head ; the lower parts of the body are silvery, the 



upper and pectoral fins are light grey, the caudal is yellow bordered 



posteriorly with black, the anal white ; there are very fine 



longitudinal lines on the sides ; eyes gilt. Count Castelnau states 



" loo. cit" that this fish is very common at Port Phillip all the 



year round, that it is called the "Mullet " there, and that it rarely 



exceeds 12 or 13 inches in length. He points out also that Dr. 



Gunther had made a mistake in referring this species to Agonostoma 



Forsteri, a distinct New Zealand fish. This species is also 



common in AVe stern Australia.

Head not so pointed as in the last species ; height five and 

 a-half times in the total length, head five times in the same ; orbit 

 four and a-half times in the length of the head. The two first 

 spines of the dorsal are joined at the base ; the caudal is strongly 

 emarginate with the lobes pointed. Colour greyish-green on the 

 upper parts, white on the lower ; each scale with an obscure 

 margin, a reddish spot on the head ; the upper part of the head 

 and lips of a dark violet colour ; fins greyish, caudal with a black 

 posterior margin, eyes of a very bright orange. 



This fish is known as the Lake Mullet, and is brought to the 

 Melbourne market from the Gipps Land Lakes. It is scarce. 



In my paper on the fishes of Port Darwin, (Proc. Linn. Soc, 

 Vol. 2, p. 360, pi. ix., fig. 8.) I described a fish under the name of 

 Agonostoma Dariviniense. It is an Eleotris and not an Agonostoma.
