The International Code of Zoological Nomenclature (ICZN) says:

Thank you Dr. Rosenberg
It seems to me, it may be impossible for someone to positively
identify a paratype. Shells do move to other collections and data
labels do become changed. A detailed description would obviously be
helpful.
The reason for my questions arose from a situation where I was
supposed to get a certain shell. Before the transaction was made;
someone had informed the seller that it was a paratype. In resonse, I
found the original description where only one paratype was mentioned and
the shell did not match its description. In the end, I did not get the
shell.
