LAURLE OF WESTERN EUROPE. 35 



This well-known species has a remarkably discontinuous 

 distribution. The large series examined is from various 

 British localities. I have not been able to compare Portuguese 

 specimens. 



Half grown young shells (pi. 5. figs. 11, 12) have 4 <u* 

 5 radial barriers in the base, at intervals of about 60 degrees. 

 The lamella? of parietal and columellar margins are very 

 strongly developed. 



According to Locard, there is a Pupa anglica Moq.-Ta nd., 

 Moll. Toulouse, 1843, p. 41, which. = Vertigo deswioulinsiana. 



Various mutations and minor variations have been named, 

 but so far as known, none of them form races. 



An it. pallida Jeffreys "shell of a lighter color, sometimes 

 whitish." Mut. alba Collier, pure white; Kenmare, County 

 Kerry, Ireland, with the ordinary form. 



Form globoso-conica West, globose-conic, small, 6 whorls. 

 -'■' | — 3 x 2 mm. Cylindracea, West., large, cylindric, 4 x 2 

 nun. Castanea West., chestnut-brown, paler around the um- 

 bilicus, peristome flesh-colored. Var. gunhildcs West., outer 

 lip very weakly lipped ; teeth well developed but without 

 any trace of a callus connecting the long angular lamella and 

 the rather widely separated outer margin. Scarborough 

 mingled with the typical form. J. R. Le B. Tomlin suspects) 

 that this is merely an immature stage of anglica (J. of Conch. 

 xvi, 1922, p. 264). 



23. I/Auria paulinoi (Locard). 



Shell very small, cylindric-ovoid, short; 7 lightly convex 

 wdiorls, regularly increasing, the last somewhat high, rounded 

 basally ; summit obtuse ; umbilicus widened, deep, a little 

 oval. Aperture small, somewhat rounded; peristome dis- 

 continuous, thick, reflected, the outer margin forming a. 

 sinus [sinulus] above, with an inner projection below th<< 

 sinus; basal margin well rounded; columellar margin nearly 

 straight. Within the aperture there are two superior folds, 

 the first opposite the sinus, attaining the margin of the 

 aperture and strongly developed, the second smaller, more 

 immersed : a fold on the columellar margin almost readies 

 to the edge of that lip ; on the lower margin another similar 

 fold; between the two a little dentiform fold, deeply im-
