The diameter equal to about 1 -47th of 

 entire length, body perfectly cylin- 

 dric, but the tail is a little com- 

 pressed, and terminates in an oval 

 point ; the anal fin commences at 

 a distance behind the vent. The 

 raphes connecting the caudal with 

 the dorsal and anal fins are a little 

 more developed than in the last, the 

 fin rays are P. U : D. 36 : A. 44 : C. 

 64. Colour dark green above, of a 

 lighter shade below. 

 (^ Hab. — Bengal. 



The caudal, anal, and dorsal fins 

 united and straight. 



N.B. — I suspect this species is fabri- 

 cated from a drawing in the Buc- 

 hanan collection Bot. Garden, Cal- 

 cutta, in which the dorsal and anal 

 are both represented by mistake 

 winding in a spiral form round the 

 end of the tail, which had been ac- 

 cidentally twisted. 



Dorsal fin contains 26 rays, the anal 

 32, and the caudal 36. 



N.B. — This supposed species was 

 made by Mr. Gray to form a dis- 

 tinct genus from the last under an 

 idea that the caudal is in the one 

 distinct, and in the other united with 

 the dorsal and anal. It is needless 

 to remark that such distinctions 

 could only have originated from 

 bad drawings. 



The diameter of the body equal to 

 about l-31st of the entire length. 

 The distance from the muzzle to the 

 pectorals equal to l-9th of the en- 

 tire length, and to l-3rd of the 

 length of the tail. The anal fin com- 

 mences about one diameter of the 

 body behind the vent. Teeth short, 

 strong and hooked, 10 forming a 

 line on the vomer, and 15 an inter- 

 rupted line on either side of the 

 upper jaw, pectorals round, P. 9 : 

 D. 39 : A. 44 : C. 60, or there abouts. 

 Colour, purple above, below red- 

 dish white ; tail dark.
