Unknown Murex
It is 33mm from Vera Cruz, Panama.

Can someone settle a little puzzle for me?  I have these listed as a Nassariidae: Bullia
   tranquebarica (Roding, 1798). A very common shell from the coastal waters of
   India. This    identification is from Wye, "The Encyclopedia of Shells." However,   other
   books show a much less elongated shell as this species.
   ("Seashells of    Eastern Arabia").  So, is it or is it not Bullia tranquebarica (Roding, 1798)??
