Pupa Lamarck (1801, Syst. Anim. s. vert., p. 88), monotype Turbo uva L. 



(Not Pupa Roding.) 

 Pupa Draparnaud (1801, Tabl. Moll. France, pp. 32, 56), for European 



Pupillidae." 



Discussion: Cerion is universally employed for the typical genus 

 of the Cerionidae (Gastropoda Pulmonata) ; the only other name 

 (Sfrophia) that has been used is preoccupied. According to Opin- 

 ion 96, Cerion is the correct name for the genus. Its replacement by 

 Pupa would be peculiarly unfortunate, as that name has usually been 

 employed in the sense of Draparnaud (=PupiUa Leach), although 

 historically both the Pupillidae and the Cerionidae (members of 

 different suborders) were included in the one genus. Except for 

 Pupa Lam., Cerion would be the prior name for the genus, even if 

 dated from what manv consider its first valid use, that by Morch 

 (T852). 



According to special reports Ijy F. A. Bather, B. B. Woodward 

 (both of London), and F. Haas, Rud. Richter. and W. Wenz (all 

 three of the Senckenberg Museum, of Frankfurt a. M.), this case 

 stands under the Rules. LL A. Pilsbry and H. B. Baker (of Phila- 

 delphia), B. Rensch (Berlin), and F. L. Chapman (Melbourne), 

 express themselves in favor of Cerion. Wolfgang Adensamer 

 (Vienna) concurs. Apparently Paul Bartsch (Washington, D. C.) 

 and L. Germain, both support Cerion, the former on basis of the 

 Rules, the latter even if suspension is necessary. T. W. Stanton, 

 speaking as a paleontologist, " would like to have the conchologists 

 agree among themselves." 



4. Olcacina Bolten, 1798, type Bulla I'ohita Gmelin, 1790. Pilsbry and Baker 

 report : 

 " Oleac'ina Roding (Mus. Bolten., II, p. no), monotype 0. volufata Roding, 



with Bulla valuta Gmelin in synonymy. 

 Glandina Schumacher (1817, Ess. Nov. Syst. Hab. Vers. Test., pp. 61, 202), 



monotype G. olivacca Schumacher (=r Btilla valuta Gmelin)." 

 Discussion: According to Opinion 96, Olcacina is the correct 

 name for the typical genus of the Oleacinidae (Gastropoda Pul- 

 monata). As Schumacher was almost as unpopular as Bolten among 

 the early conchologists, Oleacina has been in use almost as long as 

 Glandina, and is the one employed by recent writers. It seems best to 

 fix it. 



The consultants report as in Case 3. Cerion. 



7. Ncritina Lamarck, 181 6, type A^. pulligcra Linn., 1766. Pilsbry and Baker 

 report : 



" ' Ncritinc ' Ferussac (1807) and Lamarck (1809). 



Thcodo.vis, Thcodoxus Montfort (1810, Conch. System. II, pp. 350, 351), 

 type by original designation, T. lutcfiamis Montfort = Ncrita flicviatilis 

 Linne (1758).
