Redescription of (Boone, 1923) (Crustacea, Isopoda, Sphaeromatidae) from the north-eastern Pacific.

(Boone, 1923) from southern California is reviewed, redescribed, and figured. The original species description did not include figures, making it difficult to attribute individuals to the species. Carvacho and Haasmann, 1984 and Carvacho & Haasman, 1984 from the Pacific Coast of Mexico and Kussakin & Malyutina, 1987, from Furugelm Island, Peter the Great Gulf in the Sea of Japan, appear morphologically more similar to each other than to western Pacific species.
