CLASS MAMMALIA. 81 



Family DELPHINID^. 



Genus ORCA, Gray. 



Orca gladiator, Lacepede. GRAMPUS. 



John Hunter, the anatomist, records the capture of three 

 specimens of this savage and destructive animal in the River 

 Thames, towards the end of the last century (see Bell's Brit. 

 Quad., p. 446). There is, in the British Museum, the skull of 

 a specimen taken on the Essex coast, as recorded in the 

 Zoologist for 1873, P- 34 2 9> an d Dale (Hist, of Harwich, 

 p. 412) mentions another specimen. Some years since, I saw 

 two whales which had been killed in one of the creeks of the 

 Blackwater. These, I have no doubt, were of this species, 

 but no record was kept of them, and I do not recollect what 

 became of their bones. Probably they went, as usual, for 

 manure. 



Genus GRAMPUS, Gray. 



Grampus griseus, G. Cuvier. Risso's GRAMPUS. 



One of this species was found stranded in the Crouch 

 about the 5th September, 1885, just above the spot where the 

 specimen of Rudolphi's Rorqual, previously mentioned, was 

 captured. It was, unfortunately, boiled down before I heard 

 of it. I obtained, however, the remains of the skull and lower 

 jaw. These are now deposited in the British Museum. 

 Professor Flower, after having examined them, confirmed my 

 identification (Zoo/., 1888, p. 260 ; Essex Nat., vol. ii., p. 72). 

 This last-mentioned was only the fifth specimen then recorded 

 on the British coasts, and the Crouch River appears to be 

 the farthest point east and north at which this species of 

 Grampus has ever been found.
