Dear Richard,
Some years ago Poppe published a book on Angaria. He illustrates many
specimens (and describes a new species). I don't have the book myself, so I
cant't give you a proper reference. Yet, this may help.
I would be very interested to take a look at your Strombus. I regard myself
a bit of an "expert" on this family. The specimen will of course be
returned.
Kind regards,
Gijs C. Kronenberg

> 1) ANGARIA SPHAERULA/ VICDANI - Several of these, quite small. They are
not

different;

> umbilicus, tending towards pale orange as the whorl matures. Can anyone
tell

> 2) FUSINUS sp - From 90m deep. This should be a Fusinus colus, but isn't
the
> same at all. It's much more slender, with a very long siphonal canal. It
is
> 90mm long, but only 15 wide, with an orange tip, greeny brown patches
> between the early axial ribs, and then plain blue white, the axial ribs
> turning into nodules like colus. The periostracum wasn't buff coloured (I
> didn't even notice anything at all before I put it in chlorine, so it may
> have been white). The siphonal canal is very long, just longer than the
> body. The only comparison shell I have here is a Fusinus tuberculatus
> identical to the picture in Eisenberg's 'Seashells of the World'. Abbott
> (and Dance - don't let's forget the Englishman did half the work) says
that
> tuberculatus is synonymous with colus, but show a quite different shell,
> cream, with no orange tip and no blueish white shade, and much fatter. I
did
> a few comparison measurements, from my tuberculatus, Abbott & Dance,
> Eisenberg, and Springsteen & Leobrera, and this one wins on slenderness
and
> tail to body ratios.
>
> 3) MUREX sp - Small 21mm burnt orange colour - most like picture of
> Chicoreus rubiginosus in Abbott & Dance but the shoulder spines are much
> longer, frondose, and recurved. The other spines are smaller. It is also
> only a fifth of the size. It hasn't such a long siphonal canal or spines
as
> axicornis. I have 6 others, all from Bohol, 14-22mm in size, (so should
be
> mature) and identical in shape, but intense pink, with shorter shoulder
> spines.
>
>
> 4) LIMA sp - I rotted down a few of the sponges and rocks from 120m.
> Enveloped in one of the sponges there were a couple of things like a
Lima,
> the larger 25mm long, 16 wide, with a pale buff exterior, pearly
interior,
> almost obsolete ribs, and a very weak hinge line, not like normal Lima.
The
> thing gapes (no, it outright grins) all round, and it may be that the
edges
> of the shell, if they were very thin or horny, dissolved in the chlorine.
> Could it be a parasitic or symbiotic Lima, adapted to a degenerate and
lazy
> life in a sponge?
>
> 5) OSTRAEA - on one of the rocks we recovered, there is a bright pink
> oyster, with a distinct yellow streak, and a white interior, 30mm long.
It
> has a wavy margin, but not as strong or regular as a standard Lopha
> cristagalli, and the colouration is very different.
>
> 6) CARDITA sp - only one valve, and that not exactly gem, 22mm long. It
> looks most like Cyclocardia borealis in Abbott & Dance's Compendium, but
is
> pure white, and not very Northern. It also has prominent scales on the
ribs.
>
> 7) PECTEN - We now have two Annachlamys, both from 70-90m down. They are
> most like Annachlamys leoparda in Abbott & Dance's Compendium, or at
least
> the flatter valve is. There are just five distinct orange brown broken
rays
> going all the way from the margin to the umbones. On the inflated valve,
> almost every rib, except for the first 20mm of early growth, which is
plain
> creamy white, has a series of red semi circular marks, like a pile of
> saucers. The interior has prominent ribs, a dusting of very pale yellow
near
> the margins, and stronger yellow just in front of the hinge. The umbones
are
> not central, but about 40% from the left, not like the picures of
> macassarensis or leoparda (looking down on the flatter side, with the
> umbones pointing up - which is left or right, upper or lower on these
> things?). It doesn't seem to gape at the hinge, or not so much that you
> would remark on it like Springsteen does in his description of
Annachlamys
> macassarensis.
>
> 8) STROMBUS - Given to me by Rudy in Cebu (netted off Mactan). It is
quite
> unlike anything I have seen, and not in any of the books. Length 64mm,
width
> 19, spire longer than 1st body whorl. Colour dark brown with white spiral
> lines and blotches. Mouth white tending to blue inside, with thin black
lip,
> strombal notch almost missing. Early whorls have 3-4 axial ribs which
become
> obsolete on later whorls. It looks almost like a cross between a
Colubraria
> and a common Strombus urceus. What is it?
