Two typical shells of 5". striatina were collected at Saleyer Anchorage (St. 213). The 

 species has so far been recorded from the Philippines and Tuamotu Archipelago, Polynesia.

In his valuable paper on the Molluscs of Mauritius and Seychelles von Martens suggested 

 that the species 5". pistim Sowerby is probably a synonym of .S", httea (Lam.). The material of 

 the two species at my disposai is unfortunately very limited and it is not possible to form any 

 definite opinion. 



Distribution : — 5". httea has been recorded from Mauritius, Bourbon and Madagascar. 



In the "Siboga" collection there is a single valve of this species from Sulu Harbour, 

 Sulu Island (St. 104).

The shells of S. faba vary to some extent in outline and the anterior side is often rounded 

 instead of subtruncate. The shells hâve minute pits scattered regularly over the valves ; in the 

 middle area below the umbones, however, the surface shows a number of close set concentric striae. 



Dis'tribution : — S. faba was described from Bornéo, and has also been recorded from Aden. 



In the "Siboga" collection there are shells from the east side of Pajunga Island, Kwandang 

 Bay (St. 115), Ambon Anchorage (St. 231) and Pepela Bay, east coast of Rotti Island (St. 301).
