The figures show the denticles as seen microscopically under oil-immersion magnification; without that resolution they ap- pear in figure 37c as a series of small, sharp projections. One might assume from Stout's (1913) description of /. parvus that Ischyrocerus sp. A is identifiable with that species because of sim- ilarities in short coxae and small eyes. Material of Ischyrocerus sp. A.—cayucos: Phyllospadix-peixetiid grid, abundant (311 per sq. m.); nodose pink tunicates, rare, hazard canyon: algal turf on platform, moderately abundant (122 + per sq. m.); Rhodomela laryx, rare; Egregia-Laminaria holdfasts, scarce. goleta: Phyllospadix-pelvetiid grid, abundant (705 per sq. m.). pt. dume: Egregia holdfast, rare, corona del mar: loose rocks, rare;.
