LITTORINA ASPERA WAS LOCATED BETWEEN THE SUPRALITTORAL ZONE AND THE MAXIMUM LOW TIDE LEVEL, WHILE L. MODESTA WAS RESTRICTED TO THE MESOLITTORAL ZONE. THE DIVERSITY (H'N) WAS HIGHEST IN ROCKY-SHORE AREAS WITH HETEROGENEOUS SUBSTRATE, AND LOW IN AREAS WITH SMOOTH ROCKS PARTIALLY PROTECTED. THE ROCKY-SHORE CHARACTERISTICS WERE IMPORTANT IN THE DISTRIBUTIONAL PATTERNS OF THE SPECIES. CORALLIOPHILA (C.) MACLEANI SHASKY, NASSARIUS LIMACINUS (DALL), RUTHIA MAZATLANICA SHASKY, AND STYLOCHEILUS LONGICAUDA (QUOY & GAIMARD) ARE NEW RECORDS FOR THE CHAMELA BAY.
