“A large and valuable species, inhabiting along the borders of 
J^oeks, where it is often taken in crab-pots, which, however, its 
long and unyielding antennae frequently hinder it from entering. 
Keeping in companies, it also gets entangled in the trammel net, 
and in some abundance on the fishermen’s lines. It meets a 
i^eady sale in the market, though not so highly esteemed for the 
lahle as the lobster.” 
It appears to be more general on our western coasts than else- 
where. They are rare in the north, both in England and Ireland. 
The young or zcea of this species was first made known by Mr. 
P- Q. Couch, son of the author of the Cornish Pauna, at the 
“aeeting of the British Association at Dublin, 1857.
