HOHENWARTIANA. 329 



form. It is described as resembling "A. lubrica, but it is 

 longer and has a different appearance." Whether it is iden- 

 tical with Helix (Cochlicopa) lubricoides Fer., Tabl. Syst. 

 p. 51, no. 372, undescribed, is not certainly known. 



I have figured, pi. 51, figs. 10, 11, a shell received from 

 Terver as "A. lubricoides Jan." It is related to kohenwarti, 

 but differs by the much more lengthened spire, and the more 

 irregular descent of the suture, as shown in the figures. The 

 outer lip arches forward more than in H. hohenwarti. The 

 early whorls are less narrow and the penultimate whorl 

 widens less rapidly than in H. bourguignatiana. Length 6.3, 

 diam. 2mm. Italy: Milan. 



Var. iriana Pollonera. Differs from the typical form by 

 its more elevated spire, larger size, somewhat wider aperture 

 and less twisted columella. Length 7 to 8, diam. 2.25 to 3.25 

 mm. Debris of the Scrivia at Carbonara, Piernont. (POLL., 

 Moll. terr. viv. in Piemonte, Atti R. Ac. Sci. di Torino, 1885, 

 xx, 693). 



Var. psilia Bourguignat. Distinguished from the related 

 hohenwarti by its larger size, corneous tint, and the irregular 

 increase, the early whorls very close, the last three very wide.

Var. BUGESI (Bourguignat). PI. 51, figs. 3. 



Differs from H. moitessieri by the larger shell, less swollen, 

 the whorls increasing irregularly (the two upper slowly, the 

 rest more rapidly), by the less oblong aperture, smaller and 

 less narrowly angular above ; the columella is straighter, with 

 weaker truncation, and finally the last whorl descends rapidly. 

 Length 5, diam. 2 mm.; whorls 6.

I cannot see that this differs materially from H. hohenwarti. 



2. H. LOCARDI ('Bgt.' Locard). PL 51, fig. 9. 



Shell ovoid-fusiform, nearly smooth, very glossy and sub- 

 transparent. Whorls 5 or 6, the first increasing slowly, the
