Family VermetidsB. 



109. Vermetus {Thylacodes) inojyertus, Riippell. 

 Loc. Cargados Carajos. 



This is identified with a little doubt as synonymous with V. eruca, Lamarck. 



110. Vermetus (Siphoiiium) maximus, Sowb. 

 Loc. Chagos Archipelago : Salomon. 



111. Vermetus {Siplionium) sp. 

 Loc. Seychelles : Praslin I. 



A species I cannot identify with certainty bears some resemblance to the variable 

 V. centriquadrus, Valenc, which is, tyj)ically, a Western American species. 



Besides this, several specimens also occurred at Coetivy I. of a small species, with very 

 friable shell, evidently found imbedded in corals, wdtli remarkably large horny operculum 

 proportionately speaking. Probably not adult, and difiicult to name.
