Dear Listers.

I come to you with hat in hand.  I am a very poor clausiliologist, and I
need some beefing up of my nomenclature.  I have picked some names of
landsnails belonging to the family Clausiliidae from the older literature
(little interest in authors and dates; very little generic splitting) in my
quest from understanding of how snail coiling direction relates to
phylogeny, zoogeography, and evolution in this group.  There are three
groups of species listed in alphabetical order (by specific epithet) below.

Clausiliid species, all apparently from west of the Caucasus, known as
abnormally dextral:
Clausilia almissana Küster
C. bidens Draparnaud
C. bidentata Ström
Balea biplicata (Montagu)
Albinaria cretensis (Rossmässler, 1836)
C. duboisi Charpentier
C. laminata Montagu
C. macarana Ziegler
C. nigricans Pulteney
Balea perversa (Linnaeus)
C. plicata Draparnaud
C. plicatula Draparnaud
Clausilia pumila
C. rugosa Draparnaud (= C. perversa Müller non Linnaeus)
C. stentzi Rossmässler
Vestia turgida

These clausiliid taxa are known to be normally dextral:
Clausilia antilopina
Alopia bielzii (Parreys)
Alopia bielzii tenuis (E. A. Bielz, 1861)
C. colbeauiana Parreys
Sericata dextrorsa (O. Boettger, 1877)
Temesa (Neniatracta) dextroversa (Pilsbry, 1949)
C. lischkeana Parreys
C. livida Menke
C. madenensis Fuss
C. meschendorferi Bielz
Alopia nefasa M. Kimakowicz, 1894
C. purpurascens
C.semprinii
C. sykesi
C. trachelostropha
Albinaria voithi (Rossmässler)

These clausiliids are reported as occurring in both the sinistral and
dextral condition frequently (amphidromine):
Alopia fussiana
A. straminicollis
