France: on rocks below the village of Bordeau, near Aix-les- 

 Bains.

 p. 55, pi. 2. f. 3-5. 



The columella "a little concave, ornamented in the upper 

 part with a lamelliform fold, and having a distinct truncation 

 at the base ' ' seems to be the chief characteristic of this form. 



Var. aglena Bgt. PL 1, fig. 18. Shell approaching espe- 

 cially the C. liesvillei, but is distinguished by the mamillate 

 summit, non-margined suture, 7 whorls, and especially by the 

 aperture, in which the penultimate whorl has scarcely any con- 

 vexity, but forms nearly a straight line with the columella. 

 Length 5, diam. 2 mm. Ville-au-Bois-les-Vendeuvre, Aube, 

 France (Bgt., C. aglena, Rev. et Mag. ZooL, 1857, p. 15, pi. 1, 

 f. 3, 4; Amen. Malac., ii, p. 31, pi. 1, f. 3, 4). 



Var. boettgeri Hesse. PL 1, fig. 17. Differs from the type 

 by the smaller size, more slender shape, angulate columella, 

 whorls more rapidly increasing, the penultimate as high as the 

 upper ones. Length 3, diam. scarcely 1 mm. Tinos, Grecian 

 Archipelago, in flotsam of a small brook. Differs from liesvillei 

 by its slimness and the shape of the columella, which has an 

 angle in the place where there is an obsolete fold in liesvillei. 

 (Hesse, Jahrb. D. Malak. Gee., ix, 1882, p. 332, pi. 12, fig. 8.) 



Forms of Spain and Portugal. 



The Iberian forms have not been figured. In a group where 

 with the closest comparisons of specimens, species are difficult 

 to distinguish, mere descriptions are barely worth the paper 

 they are written on. The student will find all published in- 

 formation below. C. acicula and C. nanodea are also recorded 

 from the Iberian peninsula. 



C. vandalitice Servain. The whorls increase regularly and 

 rapidly; the suture does not descend much. The last whorl 

 has a regular, median convexity, not inferior, as in belonidaea. 

 The spire tapers gradually. The outer lip, instead of descend- 

 ing a little below the columellar extremity, forming an angular 

 part at the base of the aperture as in belonidaea, is on the con- 

 trary convex and rounded to the columellar border, which is
