RISSO'S GRAMPUS 
Genus Grampus. 
RISSO'S GRAMPUS. 
Grampus griseus, Cuvier. 
Plate 49. 
Closely related to the Pilot Whale, Risso's Grampus differs in the 
contour of the head which is less rounded, in the small number of teeth 
confined to the front part of the lower jaw, and also in possessing a 
high and falcated dorsal fin. The scimitar-shaped flippers are rather long, 
but shorter than those of the Pilot Whale. 
In the Transactions of the Zoological Society (vol. viii. pp. 3-13), 
Sir William Flower has given an account of this rare species taken from 
a freshly killed specimen caught in a mackerel-net off the Eddystone 
lighthouse on February 28, 1870, with a carefully coloured drawing 
of the animal. By kind permission of the Publication Committee I have 
copied this for the figure in Plate 49, and the following notes are taken 
from the description : 
" The most prevalent tint was grey varying in some parts to pure 
white and in others to deep black, but the light parts of the head and 
anterior portion of the body had a yellowish wash, and the dark parts 
a slightly bluish or purple tinge which varied much in different lights. 
" The head and the whole of the body anterior to the dorsal fin was 
generally a lighter grey, variegated with patches of both darker and 
lighter hue. The eye was surrounded by a small oval patch of black. 
The lips were mottled with black. There was a large nearly black patch
