These skulls were accompanied by the following notes : — 

 " The larger of the two skulls belonged to an individual killed off 

 Cape Melville (within the Great Barrier Eeefs), north-east coast of 

 Australia, Sept. 5, 1860. It was a female, 7|- feet in length ; and 

 from it were taken two foetuses, each 10 inches in length. The adult 

 was of a very light lead-colour above and on the sides, gradually 

 passing into the dirty leaden white of the lower parts, which were 

 covered (as also the flippers) with longitudinally elongated blotches 

 of dark lead-colour.
