These are Murex trapa.  It has relatively short, thick, slightly curved spines, and heavy sculpture on the body whorl.  Murex altispira has longer, more slender and more curved spines, and reduced sculpture on the body whorl.  There are other differences as well, but these are sufficient to separate the two.
