Because many of this group of molluscs possess shells they have had relatively more attention from conchologists than most other opisthobranchiate molluscs yet they are not so well known as they deserve to be. Many of the records already published from the area apply to shells only and since these are light and buoyant they may be carried far from the haunt of the living animal. Hence a record, based on the finding of the shell alone may not be a valid one. This applies to many of the records resulting from the collections of Col. W.H. Turton who collected shells on the beaches of Port Alfred and district. In this paper will be found records and short descriptionptions of sixteen species most of which are widely distributed in the Indo-west-Pacific biogeographic region. Some, however, are strangely local in their distribution: in particular the species of Haminea of which four appear to replace one another successively round the coast with only a slight overlap between species. The coast line from which specimens have been studied extends from the vicinity of Cape Town to Inhaca island in southern Moçambique. Collections examined originated from the Ecological Survey of University of Cape Town (U.C.T. in the records which follow) the Zoological Department of the University of the Witwatersrand, Johannesburg (U.W.) and from the author's own collection (W. M.).
