Dear Phil,

I found the following in Vaught's mollusca classification:

  FAMILY: HYDROBIIDAE
Hydrobiidae Troschel, 1857 [Gastropoda, Prosobranchia, Mesogastropoda,
Rissoidea]; Vaught, 1989: 20
Hydrobiidae Troschel, 1857 [Gastropoda, Caenogastropoda,
Neotaenioglossa];Le Renard, 1996: 40
Hydrobiidae Troschel, 1857 [Gastropoda, Streptoneura, Caenogastropoda,
Neotaenioglossa, Truncatelloidea]; Pacaud & Le Renard, 1995: 160
Hydrobioidea
SUBFAMILY: SADLERIANINAE
Sadlerianinae [Gastropoda, Prosobranchia, Mesogastropoda, Rissoidea,
Hydrobiidae]; Vaught, 1989: 22
    SADLERIANA Clessin, 1887
    BELGRANDIA Bourguignat, 1869

Belgrandia gibba Draparnaud, 1805 is cited in Cossignani, Tiziano &
Cossignani, Vicenzo, "Atlante delle Conchiglie Terrestri e Dulciacquicole
Italiane."  1995.  L'Informatore Piceno, Ancona, Italy.

This work indicated the range as the northwest corner of Italy.  It runs
about 1.5 - 2.0 mm in length.

Let me know if I can help more,

Scott

Subject:        A shell ID question

Dear Conch-L'ers,

It has been so quiet over the last few days; I assumed that everyone was
busily
drafting their wittiest responses to the
"Is-there-a-way-to-get-the-Conch-out-of-the-shell" question.  So, while we
are
waiting for the rest to pour in, I have a different question-

I have two small shells that were labeled as follows (or as best as I can
read the
handwriting):

Belgrandia gibba   Drap. var.  Tris.

Can anyone place this genus in a family for me and give me any information
about
the species and it's range?

Thanks,

Phil Liff-Grieff

PS  Someone removed the Conch from these shells many decades ago.  I assume
that
the animals did not survive the relocation process.
