Help whith identification of few shells

[dave r]

Hi there, the conch shell is <i>Strombus variabilis</i> the blotch on the columellar callous is distinctive.
The cone shell is difficult as it looks like a juvenile but I would say it is one of the forms of <i>Conus spectrum</i>.
The last shell does look like <i>Nassarius reticulatus</i> but as Mike says locality data would be helpful. It is always a good idea to include locality data and size when enquiring about identification of a specimen, this can really be useful to those trying to i.d. it.
