Dear Henk

I think Janthina exigua is also a problematic species.

with best shelling greetings

> Dear Ed and other Janthina lovers.
> Currently five species of Janthina are recognized. The names of four
species
> are quite stabilizeded:
> Janthina janthina (Linnaeus, 1758)
> Janthina exigua (Lamarck, 1816)
> Janthina umbilicata d'Orbigny, 1840
> Janthina pallida Thompson, 1841(Thompson used a manuscript name of Harvey)
> The nomenclature of the fifth species is problematic.
> Janthina globosa Swainson, 1822, Janthina prolongata Blainville, 1822 and
> Janthina nitens (Menke, 1825)
> are the names usually employed for that species.
>
> Ed note that J. violacea Roeding, 1798 and J. balteata Reeve, 1858 are
junior
> synonyms of J. janthina.
>
> In the genus Recluzia the situation is much more complicated, since a
modern
> revision has never been carried out.
> The following 12 names have been proposed in connection with Recluzia:
>
> annamitica Wattabled, 1886
> bensoni A. Adams, 1861
> erythraea Jickeli, 1882
> globosa E. Smith, 1876
> hargravesii Cox, 1870
> jehennei Petit de la Saussaye, 1853
> johnii Holton, 1802
> lutea Bennett, 1840
> montrouzieri Souverbie, 1871
> palmeri (Dall, 1871)
> rollandiana Petit de la Saussaye, 1853
> turrita Philippi, 1848
> A 13th name: petiti Sowerby in Paetel, 1888 is probably a manuscript name.
> Most probably only 2-3 circumtropical Recluzia species are hiding among
these
> names.
