Abstract
Summary This paper gives an account of the present state of our knowledge of the sandy-beach snail, Bullia, on the beaches of the Cape Peninsula. The work deals mainly with the two surf-loving species, B. digitalis and B. rhodostoma, though mention is made of B. laevissima, a species found in quiet waters. Reproductive behaviour is described for the first time. Much of the work reported concerns chemo-reception and the responses which lead to feeding. Some conclusions are reached with regard to growth and life-span. The distribution of the three species is dealt with, and the factors responsible for this distribution are discussed. Attempts to estimate the numbers of Bullia on Muizenberg beach are described. Some mention is made of water- and heat-relationships, defence mechanisms and parasites.

The reactions of specimens of Nassarius obsoletus exposed individually to controlled laboratory stimuli are as follows: Nassarius shows a light-compass reaction, but no optomotor response, and mud snails accumulate on those richest in diatoms and bacteria.

Tidal migration was also a feature of the behaviour of Bullia melanoides, and in this species too, rapid burrowing and active emergence from the substratum at appropriate times are elements in the complex of movements by which this tidal migration is performed.

Observations were made on 2 beaches during the premonsoon period (January to March) when conditions were relatively stable, and the water temperature remained about 31°C, but on the dry sand surface it reached 50°C and the amount of chlorophyll attached to sand grains is very small.

This species exhibits a form of brood protection in which the expanded foot is folded around the egg capsules to form a tubular brood pouch, and this habit is associated with the animals' occurrence on disturbed surf beaches on the tropical west coast of India.
