 Inhabits the Ganges, and water tanks in the Carnatic. 



In a drawing of a specimen eight feet long, from the Ganges, 

 the nuchal scales are placed as in Cuvicr's and GeoflVoy's figures ; 

 but in a young specimen, from the water tanks at Madras, (he la- 

 teral scales of the nuchal group are placed in the centre, opposite 

 the division between the upper and lower series of scales. In a 

 specimen about the same size in the British Museum, said to come 

 fromlndia, they are placed similarly to the latter ; as is also the case 

 fvith a full grown specimen in Mr. Gray's possession from Africa.
