Bulletin ofZoological Nomenclature 53(3) Septetnber 1996 191 Comment on the proposed conservation ofthe specific names ofAphodius rufus (Moll, 1782), A.foetidus (Herbst, 1783) and Aegialia tufa (Fabricius, 1792) (Insecta, Coleoptera) (Case 2878; see BZN 51: 121-127, 340-341; 52: 71-73, 123-125) David Krai DepartmeiU ofZoology. Charles University, Vinicna 7. CZ-128 44 Praha 2, Czech Republic I am incompleteagreement with theapplication by Krell. Stebnicka& Holm. The authors have clearly and correctly presented the facts concerning this difficult problem and they have put forward the solution which serves stability in zoological nomenclature. At least two ofthe species discussed. Aphodius rufus (Moll, 1782) and A. foetidus (Herbst. 1783), are widespread in almost the whole ofEurope and adjacent parts of Asia and their names appear not just in taxonomic studies, but with increasing frequency, in ecological studies, local faunal lists, red data books, and the like. I have given the Commission Secretariat a list of10 additional references in which all the names are used, but I can supply 30 further citations ifrequested. Alternativesolutionsmentioned,fore.xamplethatin Dellacasa'ssecondalternative (BZN 51: 340-341). even though perhaps formally correct, have been used only sporadically. Comments on the proposed conservation ofsome mammal generic names first published in Brisson's (1762) Regnum Animale (Case 2928; see BZN 51: 135-146, 266-267. 342-348; 52: 78-93, 187-192, 271-275. 347-350) (1) Hugh H. Kolb 3 High Brae. Torphichen. West Lothian. ScotlandEH48 4LX, U.K. (formerly of the Scottish Agricultural Science Agency. Edinburgh EHI2 8NJ, Scotland) I fully agree with the application to conserve 1 1 ofBrisson's (1762) generic names for mammals and am happy to support it. I note that the application (para. 5. BZN 51: 138) seeks the conservation ofthe name CuniculusBrisson. 1762 fortheSouth American pacasandthat, iftheproposal isnot approved bytheCommission. Cuniculus Brisson would be unavailableand the junior homonym Cuniculus Meyer. 1790 would become a valid name. Meyer's name relates to the European rabbit and would replace the well-known and universally used, butjunior, name Oryctolagus Lilljeborg, 1874. 1 worked on the rabbit for some years and have supplied the Commission Secretariat with a representative list of11 papers (1985-1994) which demonstrate the usage ofthe name Oryctolagus. I amfully in agreement with maintaining the generic name Oryctolagus and would oppose any move to replace it with Cuniculus.
