Dear James,
if a new species is described on only one specimen it is a holotype.
If the description is based on more specimens, are these paratypes,
but important that they are from the same locality and date. A holotype
should deposited into a museum.
So this Calliostoma is only known from this one specimen, which has
been found at that time on this locality and has been described.
