Dear Pat amd Harry,
Although I agree that the record of Voluta musica from Grand Cayman is most probably erroneous, we must think of a misidentification of Voluta polypleura. Specimens of this complex have been found at Pedro Bank, to the southeast of Grand Cayman, and Misteriosa Bank, to the west.

Good catch, Pat.
My contribution to this checklist <
http://www.jaxshells.org/cayman.htm> was (1)
integrating earlier inventories (2) imposing
phylogenetic sequence. and (3) adding lots of micromollusks.
The Voluta musica record was lifted uncritically
from Abbott (1958: 88). I have now read, I
believe for the first time, the appropriate
passage, which states "'... Salisbury reports
"one specimen from station 31, 3 ft. dredged at
3½ meters.' .... Salisbury's record is in all
likelihood erroneous, and is based upon a mixture from some other collection."
Your contribution is greatly appreciated and is
one reason we post inventories like this one on
the jaxshells website. We'll expunge Voluta
musica from the Cayman Island list. Science is self-correcting.

PS. I stumbled across the original description of
Julia exquisita at <
http://www.biodiversitylibrary.org/item/37036#page/294/mode/1up>.
It appears that Gould was providing a hint that
it was maybe not a clam - comparing it to
Smaragdinella and "some of the Bullidae, Chelidonura, for instance." HGL
