It is in the Collection of Ifaaq Swainfon, Efq. of London.
A t the fame iflands are great plenty of beautiful {hells, fuch as
Cypraa ■‘Iigrina, Mauritiana, Talpa, and others of that genus;
and numberlefs fpecies of the fmaller kinds, of which Iaft the natives
form necklaces, bracelets, and other ornaments r one ofthefe
necklaces afforded a lingular fpecies of the HeMx genus of Linnaeus,
which I was informed is a frefh-water fhelk It is outwardly
fmooth,' has feven fpires, and is- of a black-brown colour, except
the tip, which is pale-yellow : the infide is fmooth and white, and
the mouth is marginated within. It is remarkable for a knob or
tooth on the columella, but which does not wind round it, con-
fequently excludes-it from the Voluta genus of Linnaeus, to.which,
at firft fight it appeals to be related. As- I prefume it to be a
fpecies hitherto undefcribed, I have taken the liberty to give it the:
the trivial name of Apex FuJva,, or the Fellow Pip. A figure, of
it, in two views, is given, in one o f the following plates.
Specimens of this kind are in the Leverian Mufeurn,
At the mouth of Cook’s River are many fpecies of fliell-fiflr,
moft of tEem, I prefume, non defcript; and of all which I fhould
have endeavoured to have got fpeeimens, had bufmefs permitted,.
Among the bivalves we noticed Lome o f a large fpecies, of the-
cardium, or cockle genus; half a- dozen of which would have:
afforded a good fupper for one perfon ; but for a, repaft of that
kind, our men preferred a large fpecies of the Solen genus, which:
they got in quantity, and were ealily difcovered by their fpouting,
up the water as the men walked over the fands where they inhabited
: as I fuppofe it to be a new kind I have given a figure of it
in the annexed plate, ’Tis a thin brittle fhell, fmooth within andi
I without a
Cancer Haninus .
