RISSO’S GRAMPUS. 315 
A much rarer visitant occurred on February 3rd of this year, 
when a fisherman named Simpson caught a Risso’s Grampus in a 
mackerel net, about twenty miles south of the Eddystone. This 
was exhibited about the streets of Plymouth for some days, when 
I finally secured it. As our experience in preserving large por- 
poises has not been encouraging, the skin was presented to the 
Exeter Museum through Mr. Brent; and I am informed by Mr. 
James Dallas, the Curator, that he hopes to be more successful. 
The skeleton I am preparing for our Museum. Our valued 
member Mr. Spence Bate, F.Rs., has assisted me in taking 
the following dimensions: 7

The general colour was black, the muzzle and belly being of a 
greyish white, shading off into the more general tint, marked with 
scoriated lines and patches, of which the accompanying engraving 
will give some idea. The blowhole, which was single, and almost 
exactly over the eye, was of the shape of a capital © looking 
forward. ‘The flippers were scimitar-shaped ; the dorsal fin high 
and falciform. There were three small teeth on each side the lower 
jaw towards the front; none in the upper jaw. The skin was 
very thick, at one place measuring a quarter of an inch; but this 
was from one of the thinnest parts, and a good deal of it must 
have been half an inch or more. The stomach was empty; but 
as a previous example, taken near the Eddystone in February,
