Shell umbilicate, ovate-conic, the spire much narrowed, un- 

 evenly substriatulate, glossy, brown-rufous. Whorls 5, con- 

 vex, rapidly increasing, the last somewhat widened, shortly 

 ascending at the insertion. Aperture ample, semioval, tooth- 

 less. Peristome a little reflected, whitish bordered, the outer 

 margin subangularly impressed and more produced in the 

 middle, arcuate above at the insertion, the margins joined 

 by an indistinct parietal callus. Length 2 l / 2 , width l l / 2 

 mm. (Gredler).

Pupa (Vertigo) eggcri GREDLER, Nachrbl. D. M. Ges. xxii, 

 1890, p. 41. 



V. eggeri has much greater dimensions than V. genesii, and 

 differs moreover by the totally different habitus, by its conic 

 spire and more distinct striation, but it approaches genesii 

 in the strong convexity of the whorls, in the coloring (also 

 that of the peristome), and in lacking denticulation (Gredler). 



67. VERTIGO ARCTICA (Wallenb.). PI. 10, figs. 7, 8. 



Shell dextral, rimate, ovate, thin, smoothish, somewhat 

 glossy, pellucid, brownish-tawny. Whorls 5 to 5y 2 , convex, 

 the last nearly two-fifths the altitude, rounded at base, an- 

 teriorly having a somewhat swollen crest. Aperture slightly 

 oblique, semiovate or piriform, obstructed by 3 teeth : in the 

 middle of the parietal wall, on the columella, and a smaller 

 one in the palate (frequently wanting) ; peristome spreading, 

 slightly labiate, the margins joined by a callus, the right 

 margin very strongly curved above, coluinellar margin some- 

 what dilated, spreading. Length 2.5, diam. 1.5 mm.
