352 THE PROCEEDINGS OF THE LINNEAN SOCIETY 



Height of body equal to the length without caudal fin ; 

 snout short ; mouth very small ; dorsal and anal fins 

 rounded behind, the last four dorsal spines almost entirely 

 hidden by scales ; colour brownish yellow, with a golden band 

 from the commencement of the dorsal fin through the 

 eye to the breast, and another from near the back along the 

 posterior edge of the operculum and through the base of the 

 pectorals to the belly. Length 5 inches. 



I have a number of very small specimens, perhaps the young 

 of this species, but they are much darker in colour, and have 

 a double band across the root of the tail.
