STEBBING ON CRUSTACEANS [May 22, together, so that none of the smooth under-surface is visible." is just the case with a perfect specimen from the Falkland Islands 36-5 mm. long by 36 mm. broad. A carapace, 62 mm. long by 62 broad, from which the radiating granules have been removed, shows the warts or tubercles solitary or in groups, with smooth intervening spaces. Mr. Vallentin notes that this species was " Found during low-water amid a heap of rocks near Hooker's Point, Stanley, Falkland Islands. Mutilated specimens of this crab common on sands after S.E. gales. Only one perfect specimen seen." PAGURINEA. 1888.
