* I have heretofore "been under the impression that the specimen presented 
by M. Duvaucel was of the male sex ; hut I find it otherwise, and certain 
discrepancies of proportion v/hich I had suspected to indicate sexual diversity, 
may yet prove to he of specifical importance. I have never obtained a male 
of this animal. So far as can be judged from apparently a well stuflPed specimen, 
that of M. Duvaucel is of more slender form, Avith a longer rostrum ; unlike any 
that I have seen from the river Hugli. Entire length 6 feet to points of tail- 
flukes, and 1 ft. 5| inch, from gape to tip of rostrum; length of our Calcutta female 
7 feet, with ro5^rm 13| inch, from gape! The two skulls (D.E.) shew a 
similar disparity.
