John Gwyn Jeffreys
John Gwyn Jeffreys FRS (18 January 1809 – 21 January 1885) was a British conchologist and malacologist. Biography John Gwyn Jeffreys was born on 18 January 1809, at Swansea, Wales. He was the eldest son of J. Jeffreys of Fynone, Glamorgan. Jeffreys was educated in Swansea at the Bishop Gore School (Swansea Grammar School). From the age of seventeen, he was an apprentice to one of the principal solicitors of Swansea, before going to London, where he qualified as a barrister in 1838. Jeffreys worked as a solicitor in Swansea until 1856, when he was called to the bar in London. But his greater passion was for conchology. He was not satisfied simply to form a collection, but was interested in all aspects of the biology of molluscs. On 2 April 1840 he became a Fellow of the Royal Society. On 21 June that year he married Ann Nevill at Llangennech. They had a son and four daughters; and were the grandparents of the physicist, Henry Gwyn Jeffreys Moseley. In 1866 Jeffreys ret ...

Skenea Proxima
''Skenea proxima'' is a species of sea snail, a marine gastropod mollusk in the family Skeneidae.Rosenberg, G. (2012). ''Skenea proxima'' (Tryon, 1888). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=532304 on 2012-09-01 The name ''Cyclostrema proxima'' was introduced by G.W. Tryon as a replacement name for ''Cyclostrema affine'' Verrill, 1884 (now recognized as a synonym of ''Skenea basistriata'' (Jeffreys, 1877)), while he thought it was closely related to ''Cyclostrema basistriata'' Brugnone. Anders Warén thought it would probably prove a synonym of '' Skenea diaphana''. W.H. Dall thought it a synonym of ''Skenea trochoides''. Description The size of the shell attains 2.2 mm. The shell is narrowly umbilicated, faintly striate, with a few indistinct spiral lines below the suture, and numerous well defined ones on the base.

This species agrees in form and condition of the umbilical region with the ''Lissospira dalli''. But it is very peculiarly marked on the base by thin, impressed lines, running obliquely and crossing the concentric spiral lines at a large angle, so as to produce a sort of "herring-bone" pattern as shown in the figure.

Granigyra Limata
''Granigyra limata'' is a species of sea snail, a marine gastropod mollusk, unassigned in the superfamily Seguenzioidea. Description (Original description by W.H. Dall) The size of the shell varies between 2 mm and 2.5 mm. The small, white shell has almost exactly the shape of '' Trochus fulgidus'' Jeffreys, but a little smaller, with three extremely rounded whorls covered with small close-set irregular granulations of nearly uniform size like sand grains. The base of the shell has a small perforate umbilicus, into which the whorl rounds without carina, callus, or break of any kind. The circular aperture has thin, sharp, uniform, not reflected margins. This singular little shell has the typical characteristics of a ''Cyclostrema'' in its conchological features, except for its granular surface.
