I am able to confirm Lynge's opinion that G. cliloroleuca should be united with G. angusta. 

 The shells on which the two forms are based are only slightly différent shells of the same species. 



Distribution : — G. angusta was described from the Philippine Islands, and has since 

 been recorded from the Gulf of Siam. 



In the "Siboga" collection the species is represented by a single shell dredged between 

 Loslos and Broken Islands, west coast of Salawatti (St. 162).

SowERBY was certainly wrong in transferring Galeomma polita to the geniis Scintilla^ 

 as the hinore is that of Galeomma and the form of the shell also is similar to that of other 

 species of the genus. 



Distribution : — G. polita was described from the Philippine Islands. 



The "Siboga" Expédition dredged a single spécimen in Pepela Bay, east coast of Rotti 

 Island (St. 301). 



Genus Scintilla Deshayes.

For a detailed discussion of the genus Scintilla référence may be made to Dall (Ioc. 

 cit., p. 1121). As was suggested by Fischer the genus Scintilla was a composite genus origi- 

 nally, and following Adams and Dall I adopt Scintilla in a restricted sensé with Scintilla 

 philippinensis Deshayes as the type.
