36 The Cartihujinous Fishes of Lower Bengál. [No. 1, 



teeth of Sq. lamia, as figured by Müller and líenle ; but the fins differ 

 much from those oí'Sq. lamia, the peclorals being of modérate size 

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

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

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

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



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

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

 specímen, the distance from muzzle to mouth is not sufíiciently great. 

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

 many of that size. 



5. Sq. (C.) Temminckii, (M. and H.) Very comraon; but 

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



6. Sq. (G.) melanopteetjs, (Quoy andGaymard). Not common : 

 small individuáis (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, jpassim. 

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



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

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



9. Peistis antiquoetjm, Latham. Small individuáis are not 

 unfrequently 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. Pe. pectinatus, Latham. Much commoner than the other. 

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

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



11. Rhlnobatus gkanulattts, Cuv. Now and then brought; 

 sometimes from 6 to 7 ft. in length. # 



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

 is prized as a medicine by the people of Asám. It is said by thein 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 GBANTT- 

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

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

 the Ehinobatus does so hkewise. 



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

 account of Kunáwar,' remarks that " the mysterious Gangball } or • snow fish,'
