History ofCase 2919 An application for the conservation of the specific name of Lithobius piceus L. Koch, 1862 was received from Dr E.H. Eason {Bourton Far Hill. Moreton-in- Marsh. Gloucestershire. U.K.) on 30 November 1993. After correspondence the case was published in BZN 51: 133-134 (June 1994). Notice of the case was sent to appropriatejournals. A note of support from ProfAlessandro Minelli Universitd di Padova. Padova, ( Italy) was published in BZN 51: 341 (December 1994). Decision ofthe Commission On 1 March 1995 the members of the Commission were invited to vote on the proposals published in BZN51: 133. At thecloseofthevotingperiod on I June 1995 the votes were as fol—lows: Affirmative votes 21: Bock, Bouchet, Cocks, Corliss, Hahn, Heppell, Holthuis, Kabata, Kraus. Lehtinen, Macpherson. Mahnert. Martins de Souza, Minelli, Nielsen, Nye. Ride—, Savage, Schuster, Starobogatov, Stys Negative votes 2: Dupuis and Thompson. No votes were received from Cogger, Halvorsen, Trjapitzin and Ueno. Bayer was on leave ofabsence. Dupuis commented that, given the apparent taxonomic doubt surrounding the three names in question (paras. 2 and 3 ofthe application), it would be betterto give Lithobius piceus L. Koch, 1862 precedence whenever they are considered to be synonyms, rather than suppressing L. quadridentatus Menge, 1851. Kabata com- mented: 'Article 79c ofthe Code seems to mandate acceptance ofthis application. I vote for it with some reluctance, however, as I think that adherence to the principle ofpriority would not result in any significant nomenclatural instability".
