tlie head four-times and one fourth. The diameter of the eye is 

 more than the length of the snout, and two-ninths of that of the 

 head. Snout projecting beyond the cleft of the mouth, which is 

 nearly transverse. Origin of the dorsal fin nearer to the end of 

 the snout than to the root of the caudal fin, and behind the base 

 of the ventrals. Coloration uniform." 



This species was at first accepted by Count Castelnau as 

 identical with the species so well known in the Murray, 

 Murrumbidgee, and all the rivers rising to the westward of the 

 dividing range of Eastern Australia. Subsequent observations 

 however, satisfied him that the Fish of the rivers of the interior 

 was specifically distinct, and he has accordingly given it the name 

 of C. Richarclsoni. The present species C. JErebi, he has seen 

 from Western Australia, Dampier's Archipelago, the Norman 

 and the Brisbane rivers, at the last of these places said to be 

 known in the Market under the name of " Sardine." It is said 

 also to be found in the Clarence, Burnett, and Fitzroy, where it 

 is known as the Bony Bream. Whether all these localities are 

 correct, or whether some of them do not apply to the other 

 species mentioned below, is a matter I believe open to doubt. It 

 seems from all that I can gather of its habits to be a fresh- water 

 Fish, though sometimes found in the sea. As an article of food 

 it is said to be much relished in some places. Count Castelnau 

 states on the authority of Mr. Bostock of Swan River, that it is 

 known there under the name of " Perth Herring" quantities 

 being smoked with Banksia or sawdust, and sold in the fruit 

 stores. It is not probable however, that it will ever become an 

 important article of consumption, as it is evidently not gregarious 

 in its habits.

 This species differs from the preceding according to Count 

 Castelnau in being of a more convex and less elongate form, and
