 length, nearly the same in width ; legs short with 

 claws hooked ; rostrum bifid ; colour varying from 

 brown to red. May be found under stones at low 

 water.

Eiiryoiiomc aspera. Carapace seldom 

 over an inch in length ; spiny and tuber-

Xaittho riviilosa. As last, with the exceptions that 

 the carapace is more flat and that the colour instead 

 of being reddish-brown is variable, being often yellow- 

 ish red marked with pink freckles. Rare under 

 stones, at extreme low tide, about La Rocque. 



Cancer pagnrus. The edible crab. Description 

 needless. Common on rocky shores and largely 

 captured for food. Owing to the relentless way in
