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 carefiilly 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 iii 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
