With a strong similitude in the form of the head, the rostrum, the mouth, and disposition of the fins, the 
general figure of this fish is more elegant than either of the two preceding species. The lateral line bends more 
gracefully, the attenuation of the tail is more gradual, and the caudal fin is not, as in the others, covered with 
scales. 
The number and length of the digiti furnish a sufficient specific character; besides which, the scales are 
smaller, the pectoral and ventral fins acuminated at the middle, not at top, and the form of the caudal fin is 
more neat.

REMARKS. 
The Mango fish is reckoned by much the most delicate of any found at Calcutta. It is in season five or six 
months in the year, and chiefly at the same time with the Mango fruit; from which, and a resemblance in 
colour to that fruit, it probably owes its English name. 
It is not found at Vizagapatam where the Rowball is not rare. The figure now presented was taken from a 
specimen in spirits received when in India from Bengal, and in good preservation, the colour excepted. A paper 
containing a more complete description made at the time has been lost.
