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 ApDaAms’s species Singa- 
porensis; Mr. Eng. Smirn kindly tells me that that species is identical with simplea, 
A. Ad., a name which H. and A. Apams afterwards altered to Hanleyana, owing to 
its having previously been used by HANLey.
