and tapering behind. The distance from the snout to the gill- 

 opening is very nearly equal to that from the giil-opening to the 

 commencement of the dorsal fin, which is double the distance from 

 thence to the vent. The tail is only a little longer than the 

 body. In a specimen measuring in all thirty -two inches, the 

 distance from the snout to the vent measured fifteen inches, 

 leaving seventeen inches for the tail. Colour dark brown, with 

 the under side of the head and body of a pale yellow ; all the fins 

 are narrowly margined with white.

Mr. Morton got twelve specimens of this Fish in the Mary, one 

 only in a net, all the others were trapped by the blacks by being 

 forced through a narrow passage in the river formed by a kind of 

 weir of brushwood. A curious circumstance as regards the habits 

 of this fish was noticed by Mr. Morton. At the time of his visit, 

 a number of the Eucalypti on the banks of the rivers were in full 

 flower, and the blossoms as they dropped into the water were 

 eagerly seized and swallowed by the Ceratodus, and in every 

 specimen which he got, he found the stomach literally crammed 

 with these flowers.
