LAURIA. 



57 



from France to Greece. A specimen from Kalamata, Greece, 

 fig. 4, measures 2.4, 1.3 mm., 5y± whorls. 



Gredler has recorded dilucida from the Austrian Tyrol, and 

 is said to have named this form P. sempronii var. edentula. 

 I have not been able to trace the original source of this name, 

 which in any case would be later than dilucida. 



5. Lauria fagoti Westerlund. 



Shell half-covered perforate, obese, subovate, very obtuse, 

 corneous, smooth, glossy. Whorls 5, the upper ones slowly 

 regularly increasing, convex, , suture deep, the last twice as 

 large, convex, horizontal in front. Aperture semioval, the 

 external margin regularly arcuate, columella subvertical, 

 dilated and reflected above. One thin very long parietal 

 lamella and one acute tooth on the columella. Length 1.75, 

 diam. 1.25mm. (West.). 



Spain: Sarria, prov. Gerona (Cleve coll., in Upsala).

 arctica?, 1897, p. 66 ; Nachrblatt., 1894, p. 171. 



Seems to be close to sempronii, but shorter, with a columel- 

 lar lamella. Known only by the original account. 



6. Lauria caspia (Pfr.). PL 7, figs. 5, 6. 



Shell perforate, ovate-cylindric, thin, smooth, pellucid, 

 glossy, fulvous-corneous. Spire oblong, slowly tapering up- 

 ward, obtuse at apex; suture impressed. 6y 2 rather convex 

 whorls increase regularly and slowly, the last more than one- 

 fourth the length, not descending in front, rounded basally. 

 Aperture slightly oblique, truncate-oblong, with a small, com- 

 pressed, very shortly entering parietal tooth. Peristome thin, 

 the right margin narrowly expanded, sometimes somewhat 

 flexuose, columellar margin dilated, reflected. Length 3, diam. 

 li/ 3 mm. (Pfr.). 



Length 2.6, diam. 1.4 mm. Lenkoran specimen. 



Transcaucasia : Lenkoran, near the Caspian Sea, under the 

 bark of Pterocarya caspia (Dr. Sievers).
