Worcestershire Record No. 27 November 2009 p. 30
Following my note in Worcestershire Record 26 this is an appeal for records. Since then several reports have indicated that this snail is gradually spreading through Britain, probably via potted plants sold at garden centres and possibly on cars. It would be interesting to assess the current Worcestershire distribution so if you have any records for the last ten years which have not been sent to WBRC I should be glad to receive them. Please send the either to me or the WBRC through email firstname.lastname@example.org or to email@example.com or write or phone – see contacts. Many thanks.
Hygromia cinctella is a very distinctive snail and easy to identify. David Green’s description is useful and follows:
Shell brown to very pale brown, except usually for a single thin pale (often pale yellow) band around the outer rim of the shell. The outer whorl often appears generally darker owing to blackish splodges. A careful look from different angles reveals (a hand lens is useful) that the outer rim is also strongly keeled (the rim is a pale outward ridge, not a more rounded shape like other snails in the garden). Size much smaller than the garden snail and hedge snails. Shell widest width about 10-12mm adult, but you might find a smaller juvenile. Shell height 7mm. Despite being smallish, Hygromia cinctella is quite distinctive with the rounded pyramidal shape above, the somewhat flattened whorl below the rim, and lighter coloured keel at the rim. Mouth viewed-head on is oval as a general shape, not round. Underneath, the umbilicus (hole in centre) is minute, partly covered by lip. The big pair of antennae are particularly long when fully extended.
