except near the base. Peduncle of the antennae armed with short, stout spines, 

 flagellum spinulous, compressed at the base, and exceeding the body in length. 

 Abdominal segments furnished with a pair of transverse dorsal setose sulci, which 

 do not meet in the middle line except indistinctly on the sixth segment. 



Dimensions. — Types: 127 mm.-228.6 mm., ranges up to 60.9 cm. in length 

 (Eandall). 



Color. — Feet vittate alternately with red and olivaceous (Kandall). There is 

 a large range of color variation, from almost black, through shades of dark 

 mahogany, reddish purple, to a light red color. Fishermen speak of albino speci- 

 mens. ... In examining traps laid among the kelp all shades were found in the 

 same trap (Allen). 



Type Locality. — California. 



Distribution. — San Luis Obispo, California, to Rosalia Bay, Lower California. 

 To a depth of 35 fathoms (Allen). Mexico (Ortmann, Streets). Except for one 

 immature specimen in the collection of the National Museum, labeled Monterey 

 Bay, this species has never been recorded north of San Luis Obispo, California. 



Bernards. — This is the common ' ' lobster ' ' of the Pacific coast. It inhabits 

 rocky ledges in rather deep water, and is taken in considerable 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 

 inward (Stimpson). The young of the lobster are often found in the tide pools 

 at Laguna Beach (Hilton).
