Ceratia and Setia are invalid and must he replaced by (probably) 

 some of the names given by Monterosato. 



Genus Adeorbis S. ^^ Wood. 

 I have been able to prove that this name must be replaced by 

 Tornus Turton & Kingston (Proc. Malac. Soc, Lond., vol. xi., p. 171, 

 1914). As it is considered of family rank the family name nmst 

 also be changed to Tornidce. 



Genus Natica Adanson. 

 Natica dates from Scopoli, as recognised in the revised List, 

 but the genus does not occur in British waters. In the list all 

 the British species are referred to the subgenus Lunatia Gray. 

 This must be given generic rank but the name to be used appears 

 to be Ainpulliiia Bowdich or Euspira Agassiz. 



Genus Triforis Deshayes. 

 Tills must be replaced by Triphora Blainville, though it may be 

 that the British form is generically distinct. 



Genus Newtoniella Cossmann. 

 Cerithiella Verrill must replace this name. I indicated this 

 emendation in the Proc. Malac. Soc, Lond., vol. ix., p. 260, 191 1, 

 and my conclusion has been confirmed by Thiele and E. A. Smith. 



Genus Scala Humphrey. 

 Humphrey's work is not admissible and the name to be used is 

 Epitonium Bolten. Again, when these matters come under care- 

 ful consideration the British shells may be considered generically 

 distinct from the type of Epitonium. 



Genus Solarium Lamarck. 

 Architedonica Bolten has priority and is now commonly in use as 

 is the family name Architectonicidce. 



Family Pyramidellidse. 



Dall & Bartsch's Monograph must be carefully considered, but 

 neither the nomenclature nor cla'ssification can be entirely accepted. 

 More study than I have given this group is necessary to outline 

 all the alterations to be made, but that such are inevitable is obvious 

 from my rough notes. 



Family Eulimidae.' 



Whether Eulinia be retained as distinct from the prior Melanella 

 the family name must be changed to Melanellidce. The subgenus 

 Leiostraca must be generically separated and the name changed to 

 Subtilaria Monterosato as Leiostraca is preoccupied. 



I since this was penned I have deiermined Stroinbifciriiiis Costa as applicable and anterior 

 to Sithnlaria and the family name would be Stroiidnformidw. Also Melanella is not appar- 

 ently separable from Euliina.
