There can be no doubt that the species S. digitatus Perry, S. costahis Lam., 5". imclti- 

 lamellata Lam. (ex parte) and 5". petroseliniun are ail based on the Chemnitzian species 

 S. foliaceus. Fulton lias rightly adopted for this species Rôding's name S. pes-asiiiimis. 



S. foliacetis has a pondérons shell and the surface is covered with strong ridges, 6 — 8 

 of which bear elongated foliaceus spines. 



Distribution : — S. pes-asininus is widely distributed in the Pacific Océan, and has also 

 been recorded from Mauritius. 



The "Siboga" expédition collected a worn old spécimen at the Anchorage off Pulu 

 Kawassang, Paternoster Islands (St. 40) and a young shell in the Bay of Badjo, West Coast 

 of Flores (St. 50).
