A little-known form, said by Bourguignat to inhabit Sicily 

 also. It is distinguished by the mamillate apex, very oblique 

 aperture, the strong descent of the last whorl to the aperture*, 

 and the crystalline appearance. 



14. A. MAROCCANA (Mousson). 



Shell imperforate, subcylindric, glossy, polished, translu- 

 cent, entire, white-corneous. Spire slowly, convexly taper- 

 ing, the apex rather large, somewhat obtuse, corneous ; suture 

 lightly impressed. Whorls 6, slightly compressed, the last 

 two descending, last whorl about one-third the length, elon- 

 gate rounded. Aperture nearly vertical, (at an angle of 85 

 degrees with the axis), semicircular. Peristome unexpanded, 

 rather obtuse ; margins joined by a thin parietal lamina, right 

 margin circular; columellar and basal margins defective. 

 Length 5.2, diam. 2.5 mm. 



Marocco: Rerey Valley, on travertine.

This form agrees with no species known to us. It differs 

 from the Algerian A. psathyrolena Bgt. by the less conic, 

 more cylindric, convexly increasing shell of 1 to 1% whorls 

 less, by the regularly rounded aperture, with a layer over 

 the parietal margin which is thinner and retreats more in 

 the aperture. Unfortunately the columella and basal margin 

 are injured. (Mouss.).
