Numbers were observed in May 1840, at Singapore; they were, 

 however, all dead, and their colours apparently somewhat faded. The 

 fish is considered excellent by the natives, and eaten both fresh and 

 dried. At Malacca it appears to be of rare occurrence, and at Pinang 

 no specimen was observed during upwards of four years search. The 

 fishermen judging from a drawing, asserted that they were acquainted 

 with the species, but they invariably brought Platax ocellatus, Cuv. 

 and Val. instead, which in colours and their peculiar distribution, 

 certainly offers a remarkable resemblance to the present species.

 fourth filamentous, sometimes double the length of the body, resem-
