 Hob. Shore and trawl, Hontjes Bay and Saldanha Bay. 



Acanthochites Garnoti, Blainville. 



Hob. Trawl, False Bay, May 8, 1904 ; Hontjes Bay, shore, and trawl ; Saldanha 

 Bay, shore and trawl. 



A fine and well-known species. 



Bullia annulata (Lam.). 

 /Toft. Trawl, Saldanha Bay, 9-10 fathoms. 



Bullia Isevigata, Chem. [Itevissima, Gmel.]. 

 Hal>. Shore, Hontjes Bay, Saldanha Bay, May 20, 1904. 



Mytilus editlis, L., var. mcridionalis, Krauss.

 Hab. Shore, Hontjes Bay, Saldanha Bay, 25 fathoms 



Tapes pullastra (Montagu). 



Hab. Trawl, Saldanha Bay, 25 fathoms. 



We cannot separate the several examples, all perfect, that were gathered at the above 

 locality, from the European species. It is also recorded by KRAUSS, from Natal and 



Algoa Bay.* 



Oxystele impervia, Menhe. 



Oxystele tigrina, Chem. 

 Hal). Trawl, 25 fathoms, Saldanha Bay ; O. tigrina also occurring at Hontjes Bay, 



Crepidula hepatica, Desh. 

 Hab. Trawl, 25 fathoms, Saldanha Bay. 



Gyrineum (Argobuccinum) argus (Gmel.). 



Hab. Hontjes and Saldanha Bays, 5-15 fathoms. 

 G. vexillum (Sowb.) seems synonymic. 



Phos plicosus, Uunker. 



This, which is the Nassa speciosa (A. Ad.), is a handsome species with certain 

 characteristics of both genera, the Nassoid element, in our opinion, prevailing. We 

 should therefore be inclined to restore it to the genus Nassa.
