This is the common "lobster" of the San Francisco 

 market ; and is the langouste of the French. It inhabits 

 rocky ledges in rather deep water, and is taken in consid- 

 erable numbers by the fishermen at Santa Barbara and 

 other ports on the coast south of San Francisco. North of 

 this point it is never found. The traps, or " pots " used in 

 their capture are similar to those in which lobsters are 

 taken on the New England coast, consisting of a strong 

 wooden basket, with a funnel-shaped entrance projecting 

 inwards. The bait used, however, is generally meat of 

 some kind rather than fish.
