Egg Capsules and Young of the Gastropod <i>Pyrulofusus deformis</i> (Neptuneidae) at Barrow, Alaska

Résumé

Describes two egg capsules of snails collected in 1963, and compares shell dimensions of three juveniles from one of the capsules with those of subadult and adult animals. The large capsules and few, large, non-pelagic young that develop in them are interpreted as an adaptation for reproduction in cold seas.
