sliould be fortified \>y an examination of the jaw and lingual mem-, 

 brane, lint for my own part, 1 am satisfied that it belongs there. If 

 this is confirmed, Alsea takes the place of Sphyradium, Agassiz, 1837. 



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

 therefore type Pupa secale. Encore, Agassiz in Charpentier, 1837, 

 was proposed for P. tridens and P. quadridens. I do not think these 

 can be regarded as different genera, but the characteristic European 

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

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

 commonly known as Pupa, subg. Pupilla. 



4. If Alsea == Sphyradium, and Encore = Abida, all the species of 

 Jamhiia were provided for by 1831. If Sphyradium is distinct from 

 Alsea, apparently the diagnosis of Jaminia prevents us from using 

 that name for Sph.yrudium. 



5. Jaminia is therefore either Abida or Pupilla, both published in 

 the same \\oi k. Abida has in its favor the figured example ; Pupilla 

 has Mr. B. B. Woodward's decision. Apparently priority of place 

 should decide the matter. 



6. Dr. Dall informs me that in Turton Pupilla umbilicata is on 

 p. 98, P. mar gin at a (our muscorum') on p. 99 ; Abida secale on p. 101 

 as a synonym of Vertigo secale (Draparnand) Turton. Hence Pupilla 

 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 Pupilla is affected if we regard 

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

 umbilicata and muscorum in different genera: 



8. Our forms of Pupilla stand thus : 

 Pupilla muscorum (Linne). 



b. unidentata (C. Pfr.). 



c. bigr.anata (Rossm.). 

 Papilla hebes (Ancey). 

 Pupilla blandi Morse. 



b. sublubrica (Ancey). 



c. obtusa (Ckll.). 



d. alba (Ckll.). 

 Pupilla sonorana (Sterki). 



. b. tenella (Sterki). 

 Pupilla syngenes (Pilsbry). 



b. dextroversa (Pils. & Van.). 

 Pufiilla sterkiiiua (Pilsbry).
