XVIII.—The Marine Mollusca of the Scottish National Antarctic Expedition

Abstract
Since we had the pleasure of working out the Mollusca obtained by the Scottish National Antarctic Expedition, Dr W. S. Bruce has kindly transmitted to our care some additional material, overlooked in the first instance, and taken (a) from deposits from jars in which Sponges were placed; (b) from Algæ and other growths, principally coming from Scotia Bay; and (c) from a new species of Cephalodiscus.
