Summary. — The following six generic names of MOLLUSC A are hereby 

 placed in the Official List of Generic Names, with types as Stated: Ccrion 

 (uva), Olcacina {valuta), Ncritina {pnlligcra), Clausilia (nigosa), Vitrina 

 ipellucida), Tornatellirm (clausa). 



Presentation of case. — Drs. H. A. Pilsbry and H. Burrington 

 Baker have made application to the Commission to accept twelve 

 generic names as " nomina conservanda " [should read " in the 

 Official List of Generic Names "] : 



1. Ampullaria Lamarck, with Helix ampullacca Linne as type; 



2. Auricula Lamarck, with Voluta auris-inidae Linne as type ; 



3. Cerion Roding, with Turbo uva Linne as type ; 



4. Oleacina Roding, with Bulla voluta Gmelin as type ; 



5. Bithynia Leach, with Helix tentaciilata Linne as type; 



6. Cyclostoma Draparnaud, with Nerita elcgans Miiller as type; 



7. Ncritina Lamarck, with Nerita pnlligcra Linne as type ; 



8. Clausilia Draparnaud, with C. rugosa Draparnaud as type ; 



9. Vitrina Draparnaud, with Helix pellueida Miiller as type ; 



10. Artemon Beck, with Solarium candiduni Spix as type; 



11. Cochlicopa Ferussac, with Helix lubrica Miiller as type; 



12. Tornatellina Pfeiffer, with T. clausa Pfeiffer as type. 



Discussion. — The twelve names in question were 'submitted to 

 thirteen specialists as consultants who are familiar with the cases and 

 with whose work these names are more or less intimately involved. 



Pronounced differences of opinion as to the best course to pursue 

 exist in regard to six of these names. 



In regard to the other six names, one specialist sup])orted " sus- 

 pension," one opposed "suspension" (without details), one saw no 

 special cause for " suspension," while five who opposed suspension 

 maintained that the six names in question are valid under the Rules 

 and therefore do not call for Suspension. 



The situation, is thus presented that six of the names for which 

 suspension is asked, in order to stabilize the nomenclature, can (on 

 basis of expert testimony of five specialists) be adopted in the Official 

 List without valid formal objection by any of the thirteen consultants 

 in question. The data on these six names follow :
