the Beluga itself. The following list of names by which it is 

 known on different parts of the coast, may be useful in ad- 

 dition to the figure, which we now give, Plate VI, from 

 Buchanan's unpublished drawings. 



Sele, Bengal, (Buchanan.) 



Suleah, Bengal, (Anonymous.) 



Seer, in Scinde, (Heddle.) 



Dara, Bombay, (Heddle.) 



Lukwah, Arrakan, (Bogle.) 



Ka-tha, Tenasserim. The small or young ? (O'Reily.) 

 Ka-ku-yan, Tenasserim, the large when in season, (O'Reily.) 

 Kala mine, Tranquebar, (John.) 

 Pole-kala, Pondicherry, (Leschenault.) 



Note. — The species is distinguished by the great size of its air vessel, 

 and by the presence of five tendrils or bristling feelers placed on the 

 breast on either side below the pectoral fins. We have ascertained that 

 Polynemus quadrifiles, distinguished by four tendrils on each side, has 

 no air vessel whatever. We had before pointed out the same pe- 

 culiarity in Polynemus paradiscens, so that Polynemus Sele, or as it might 

 now be appropriately named Polynemus gelatinosus, is not to be mistaken 

 for any adjoining species. 



Calcutta, 26th February, 1842. 



Extract of a Letter from Assistant Surgeon J. M'Clelland, to G. A. 

 Bushby, Esq., Secretary to the Government of Bengal, fyc. fyc. fyc. 

 under date 26th February, 1842. 



As the experiments were not undertaken with the previous sanction 

 of the Government, I cannot in consequence make any claim for the 

 actual cost with which they were attended ; but if their utility be allowed, 

 and the results be found to prove of practical interest, I may then trust 

 to the liberality of His Lordship for the reimbursement of that deficiency, 

 which will appear on comparing the debtor with the credit side of the 

 Isinglass account for 1839-1840, and also for 183 rupees, the actual cost 

 of 61 seers of Isinglass, forwarded through the Government as a sample 

 to the Honourable Court.
