In 1986 and 1989 a land snail survey was carried out on Rodrigues.This was followed up by examination of collections in the Natural History Museum, London (NHM) including that of Dr E. H. Madge.A total of 27 native snails were recorded, of which 5 species were extinct and a further 3 species probably extinct.A total of 11 introduced snails and slugs were recorded.

Recent survey work in England and Wales has revealed several disjunct populations of Vertigo angustior from the Gower to East Anglia.Most of these have been from rich fen in saltmarsh/dune and heath transition zones (e.g.Killeen, I. J.The Land and Freshwater Molluscs of Suffolk.Suffolk Naturalists' Society, Ipswich (1992)).The most northerly known population is from mossy runnels on limestone pavements at Gait Barrows N.N.R. North Lancashire (Marriot, D. K. & Marriot, R. W. J. Conch., Lond.31: (1982) p. 72).There are, however, two old records from Scotland.W. Baillie (

The purpose of this application is to confirm as correct the original spelling of the name Chtenopteryx Appellof, 1890 for a genus of comb-fin squids.The unjustified emendation to Ctenopteryx was made in 1900, and this spelling has been universally used until very recently although with citation of Appellof as author.However, it is a junior homonym of the coleopteran subgeneric name Ctenopteryx Flach, 1889.The most appropriate course of action is to confirm Appellof's original spelling and to adopt the corrected spelling CHTENOPTERYGIDAE Grimpe, 1922 for the derived family-group name.

It has since been recorded from two further sites: one on the west coast of Ireland and the other on the east coast of Kent.The first site lies in Tralee Bay on the Dingle peninsula, Co. Kerry, Ireland (5217.2'N,1011.7'W).A single live specimen of N. dolioliformis was retrieved from a sample of mixed red and brown algae, collected from large isolated boulders in a sheltered, sandy bay.The associated molluscan fauna was very rich and included two other pyramidellids, Odostomia turrita and Brachystomia scalaris.The species was then found again at Joss Bay, N of Broadstairs, Kent (5122.9'N,0127.1'E).The habitat consists of an extensive wave-cut Chalk platform to the north of a small sandy bay.A small sample of mixed algae yielded 5 living specimens of N. dolioliformis along with Partulida spiralis and Brachystomia scalaris.'The other molluscs in the algae sample comprised the low diversity of species generally associated with this part of the Channel (e.g.Rissoa parva, R. interrupta, Lacuna pallidula).At both sites the rocks were extensively colonized by the tube dwelling polychaete Pomatoceras triqueter (L.).This is a known host of several pyramidellid species (Fretter, V., Graham, A. & Andrews, E., J. moll.Stud., Suppl.16 (1986) pp.557-649).The host of N. dolioliformis is apparently unknown, but would appear to be also associated with Pomatoceras.These three recent records indicate that N. dolioliformis is geographically widespread in the southern British Isles, however the lack of records from other localities on the south coast suggest that it is genuinely rare.
