The chele or large claws, which in this fpecies are 
pretty exactly equal, are ferrated on the edges by a double 
feries of fharpened protuberances. The legs are alfo 
ferrated proportionally in the fame manner. The tail 
(which forms the principal fpecific charaéter) is moft 
{trongly muricated on each fide with a treble row of 
large, pointed tubercles, between which are difpofed here 
and there a few fmaller ones, fo as to invade a little the 
exact feries in which the principal ones are difpofed. 
The colour of this animal (fo far as can be colleéted from 
the {pecimens preferved in fpirits) is moftly red, or like 
that of a boiled lobfter ; but blue on the fides of the claws 
and fome other parts. 
Its place in the genus fhould be next to the Cancer 
Homarus, to which it is moft allied, though differing 
widely as a {pecies. |
