COCHLICOPA. 319 



Var. litauica Westerlund. Turrite, slender ; whorls 6, con- 

 vex, the last strongly convex; suture strongly descending to- 

 wards the aperture. Length 5, diam. 1.5 mm. Lithuania 

 (Westerl.). Cionella lubrica var. litauica WESTERL., Fauna 

 iii, 1887, p. 148. 



Var. sinistrorsa Goldfuss. Shell sinistral. Wormlitz near 

 Halle, Thuringia (Groldfuss, 1900). Locard also has noted 

 a sinistral specimen, Variations Malacologiques i, p. 220, 1880. 



Var. curta Clessin. Shell short with broad base, the last 

 whorl comprising only one-third the total length; length 5, 

 diam. 2.3 mm. Danube at Regensburg. (Clessin, 1908). 



Ic. C. LUBRICA COLUMNA Clessin. PL 49, fig. 39. 



Shell turrite, column-shaped, with obtuse, conic apex, 

 smooth and glossy; with 6 very slowly increasing, not much 

 overlapping, whorls, the suture very little impressed. Aper- 

 ture long ovate, ending above in a very acute angle; peris- 

 tome thickened, reddish. Length of the mouth one-third that 

 of the shell; columella making a very weakly marked angle 

 with the parietal wall. Length 5, diam. 1.8 mm. (Clessin).

Clessin further states that C. columna differs from C. lu- 

 brica by the longer spire, less convex whorls, smaller and nar- 

 rower aperture. The whorls overlap less, so that the spire 

 is more cylindric than conic. The aperture is more lateral 

 than in lubrica. It resembles var. maderensis. 



Dr. Babor's figures of pleistocene specimens (Die Weich- 

 thiere des Bohmischen Plistoeaen und Holocaen, in Archiv 

 f. Naturwiss. Landesdurchforschung von Bohmen, xi, 1903, 

 no. 5, p. 33, figs. 10) do not seem to represent the real 

 columna.
