Pereopods 1 and 2 of Californian specimens, especially in females, 

 have very stout, nearly subcircular second articles as shown in the 

 figure. Specimens from more southerly latitudes, such as Bahia de 

 San Quintin and Bahia de Los Angeles, Baja California, have nar- 

 rower second articles, more typical of the drawings made by Sars 

 (1895) and others in the literature.

 sq. m.). cayucos: kelp holdfasts, moderately abundant; Phyllospadix- 

 pelvetiid grid, scarce (128 per sq. m.); buried cobbles, scarce; Macro-

 to most abundant species; Amaroucium sp., scarce, hazard canyon:

Distpibution. — Cosmopolitan in tropical and warm-temperate 

 seas, extending into cold temperate seas as far as Norway and Puget 

 Sound (specimens at hand), a tube builder requiring protection from 

 surf, often nestling in biogenic structures such as phragmatopomid 

 masses, especially abundant in lagoons and estuarine mouths, 0-130 m.
