36 The Cartilaginous lushes of Loicer Bengal. [No. 1, 



teeth of Sq. lamia, 'as figured by Muller and Henle ; but the fins differ 

 much from those ofSQ. lamia, the pectorals being of moderate size 

 and remarkably falcate : tail and posterior fins conspicuously black-mar- 

 gined. Sq. Milbeeti is noted from India in Dr. Gray's British 

 Museum catalogue; and tbe present is perhaps Dr. Gray's Indian 

 species, though probably distinct from Sq. Milbeeti (verus). 



4. Sq. (C.) gangeticus, (M. and H.) In Muller and Henle's 

 outline of the lower surface of the head, drawn evidently from a dry 

 specimen, the distance from muzzle to mouth is not sufficiently great. 

 I have not known this species to exceed 7 ft. in length, but have seen 

 many of that size. 



5. Sq. (C.) Temmikceii, (M. and H.) Very common; but 

 rarely exceeding 5 ft. long, so far as I have observed. 



6. Sq. (C.) melanopteetts, (Quoy and Gaymard). Not common : 

 small individuals (under 3 ft.) occasionally brought, but we have the 

 teeth of one which must have been at least 6 or 7 ft. 



7. Sphyenias Blochii, (Val.) : Zygcena laticeps, Cantor, passim. 

 Common. The largest specimens rarely exceed 4 ft. in length. 



8. Galeoceedo tigeintjs, M. and H. One large specimen, 

 obtained towards the mouth of the river. Length 11 ft. 



9. Peistis antiqtjoeum, Latham. Small individuals are not 

 unfrequeatly brought to the bazar. We have a snout or rostrum in 

 the museum 5 ft. in length and 11 in. broad at the hindmost teeth. 



10. Pr. pectinatus, Latham. Much commoner than the other. 

 A mutilated specimen and portion of the snout of a larger one were 

 sent to the museum from Asam (!) some years ago by Col. Jenkins. 



11. Ehinobatus GBANTJLATTJS, Cuv. Now and then brought; 

 sometimes from 6 to 7 ft. in length.* 



* Col. Jenkins heard much of a ' snow fish' of great rarity, the skin of which 

 is prized as a medicine by the people of Asam. It is said by them to inhabit 

 the snows of the Butan mountains ! Sending me some fragments of the skin for 

 examination, there was no difficulty in recognising the Rhinobatus gbanu- 

 iatus : probably procured towards the sea ; but as Peistis pectinatus and 

 Hypolobhus sephen ascend many hundred miles up the great rivers, perhaps 

 the Ehinobatus does so likewise. 



In J. A. S. XIII, 176, the then Lieut. J. T. Cunningham, in his ' General 

 account of Kunawar,' remarks that " the mysterious Qangball, or ' snow fish,'
