LAURIA. 51 



dina Locard, Ann. Soc. Agric. Lyon (7), iii, 1895 (1896), p. 

 216. 



This appears to be intermediate between L. cylindracea and 

 sempronii, having the color and sculpture of the latter, but 

 the size and columellar lamella of cylindracea. It has not 

 been figured, and is known by Locard 's account only. 



The description of variety L. umbiUcata margieri, Bull. 

 Soc. Corse, xxii, 1903, p. 278, is not accessible to me. 



Lauria c. poupillieri (Bgt). PL 6, figs. 16, 17, 18. 



Shell subperforate and curved-rimate, obesely subcylindric, 

 thin, very glossy, subpellucid, corneous, smoothish, very 

 sharply striatulate under a lens. Spire obese, not very high, 

 the apex obtuse. Whorls 7, slightly convex, slowly increas- 

 ing, separated by a moderately impressed suture, the last 

 slightly larger, gibbous and compressed at base, at the aper- 

 ture a little contracted and strongly ascending in front. 

 Aperture slightly oblique, semiovate, tuberculously thickened 

 at the insertion of outer lip, and with a minute spirally en- 

 tering lamella. Columella straight. Peristome whitish-thick- 

 ened, flat, a little expanded and reflected, the outer margin 

 angularly bent, margins approaching. Alt. 4, diam. 2 mm. 

 (Bgt.).

Pupa poupillieri Bourguignat, Malac. d'Algerie, ii, 1864 r 

 p. 89, pi. 6, f. 4-7. 



By its widely open umbilical region it somewhat approaches 

 L. umbilicus Roth. Not seen by the author. 



Lauria cylindracea anconostoma (Lowe). PL 6, figs. 10, 11, 12. 



Lip decidedly narrower than in cylindracea; angular la- 

 mella less thick, generally not connected with the outer lip- 

 insertion. Length 3 mm. (fig. 11) to 4.3 mm. (fig. 10). 



Madeira (type loc), in the low and intermediate zones, 

 abounding about walls and cultivated grounds, seldom ascend- 

 ing higher than 2500 ft.; also on the Desertas. Canaries: 

 Fuerteventura, Teneriffe, Hierro, in the zone of cultivation.
