1839.] On three new species of Musk. 203 



nued inability to establish the species upon a more solid basis than that 

 of distinction of colour. The partial investigations which I have been 

 enabled to make, strongly favour, however, the supposition that the 

 superficial diagnostics are supported by others of more importance in the 

 form of the crania, and in the structure and position of the musk pod. 

 And, though I am still unable distinctly to expound these latter differ- 

 ences, I think it may stimulate curiosity to indicate summarily the 

 three presumed species as marked by their diversities of colour, in the 

 hope that attention may be thence drawn to the structural peculiarities 

 which I believe to exist in the sculls, and in the musk bags. 



1st. Species, Mosehus chrysogaster, nobis. Bright sepia brown 

 sprinkled with golden red ; orbitar region, lining, and base of ears, 

 whole body below, and insides of the limbs, rich golden red or orange ; 

 a black-brown patch on the buttocks posteally ; limbs below their 

 central flexures fulvescent. 



2nd. Species, Leucogaster, nobis. Body above, and the limbs deep- 

 er brown sprinkled with fulvous : below the head, neck, and belly, 

 together with the insides of the ears, and the orbits, hoary white. 



3rd. Species, Saturates, nobis. Throughout saturate dusky brown, 

 somewhat paler below : chin only, and lining of the ears pale and 

 hoary. 



Drawings of the above animals were transmitted to London, through 



the Society, in May 1836.

Art. IV. — On Isinglass in Polynemus sele, Buck., a species which is 

 very common in the Estuaries of the Ganges. By J. McClelland, 

 Assistant Surgeon. 



There are nine species of Polynemi, or Paradise fishes, enumerated 

 by authors, and although they are all pretty well described, I am not 

 aware of any more valuable property being known regarding them than 

 their excellence as an article of food, of which we have a familiar in- 

 stance at this season in the Pol. paradiseus, or Mango-fish, TupsiMuchi 

 of the Bengalese. 



Buchanan has five species in his work on Gangetic Fishes, but three 

 of these are small, and probably varieties only of the Tupsi; two of them 

 however, are of great size, and so common in the estuary of the Hoog- 

 ly that I have seen numerous hackeries, or bullock carts, conveying 

 them to the Calcutta bazar, during the cold season. They are not
