sliOLild be i'ortilied liy :in exiiniinalion of tlie jaw and lingual mi-nri- 

 bnine, but for my own part, 1 am satisfied that it belongs there. If 

 this is confirmed, Alseu takes the place of Sphyrudium, Agassiz, 1837. 



3. Abida, Leacli in Turton, 1831, has for its sole example and 

 tiierefore type Pupa secale. Encore, Agassiz in Cliarpentier, 1837, 

 was proposed for P. trideus and P. qiiadridens. I do not think these 

 (^an be regarded as difterent genera, but the characteristic European 

 group of " Pupa " secale, P. tridens, P. qvadindens, etc., surely de- 

 serves to rank as a valid genus, separate fiom the circumpolar group 

 commonly known as Pupa, subg. PupiUa. 



4. If Alsea = Sphyradivm, and Encore = Ahida, ail the species of 

 Jamhiia were provided ior by 1831. \i Sphyradhnn is distinct from 

 A/sea, apparently the diagnosis of Jaminia prevents us from using 

 that name for Spliyradium. 



f). Jamiiiia is therefoie either Ahida or PupiUa,ho\\\ published in 

 the same work. Abida lias in its favor the figured example ; PupiUa 

 has Mi-. B. B. Woodward's decision. Apparently jjriority of place 

 should decide the matter. 



6. Dr. Dall informs me that in Turton PupiUa nnibilicata is on 

 p. 98, P. marginala (our niuscorum) on p. 99 ; Abida secale on p. 101 

 as a synonym of Vertigo secale (Drapainand) Turton. Hence PupiUa 

 was first removed, and Jaminia stands as the proper name for Abida, 

 with Eucore as a section. 



7. I do not think the status of PupiUa is affected if we regard 

 umbilicata as its type, for I cannot imagine any one could place 

 umbilicata and muscorum in different geneia: 



8. Our forms of PupiUa stand thus : 

 PupiUa muscorum (Linne). 



b. unidentata (C. Pfr.). 



c. bigranata (Rossni,). 

 PupiUa hebes (Ancey). 

 PupiUa blandi Morse. 



b. sublubrica (Ancey). 



c. oblusa (Ckll.). 



d. alba (Ckll.). 

 PupiUa sonorana (Sterki). 



b. tenella (Sterki). 

 PupiUa syngenes (Pilsbry). 



b. dextroversa (Pils. & Van.). 

 PupiUa sleiLitiiiii (rilsl.r\).
