YNU Conchological Section Report for 2017

摘要

During 2017, to the end of October, 428 1km square species records have been added to the Yorkshire non-marine mollusc database. These comprise 76, 70, 130, 46 and 106 records for VC61-VC65, respectively, made up of 38 records of freshwater molluscs and 390 of terrestrial. These figures are provisional, however, as our files run until the end of December, when most records are submitted; thus, 2016 records totalled 1,351 at the year-end. The outstanding record this year is of the Ghost Slug Selenochlamys ysbryda collected by Victor Soria-Corrassca of Sheffield University from Redcar Road, Sheffield on 25 September (SK33328731) identified by Ben Rowson (National Museum of Wales).
