On the label of the specimens of D. dilecta, A. Ad., in the British Museum, 

 D. striatissima, Sowerby, is given as a synonym ; I very much doubt whether this 

 is correct, as Sowerby in "Thesaurus Conchyliorum" (p. 673) refers his species to 

 "Sect. 6: Edge of the dorsal area raised above the circumscribing line," a feature 

 which is not to be found at all in D. dilecta, A. Ad.

By comparisons in the British Museum I have convinced myself that the 

 small specimen from the Gulf of Siam corresponds with Adams's species Singa- 

 porensis; Mr. Edg. Smith kindly tells me that that species is identical with simplex, 

 A. Ad., a name which H. and A. Adams afterwards altered to Hanleyana, owing to 

 its having previously been used by Hanley.
