ii6 Quarterly Journal of Conchology. 



51. B. montanus /^nr/-. — Speyerhof, Heidelberg, and forests 



on the banks of the Rhine, near Mannheim. 



52. B. obscurus AIull. — Abundant. 



53. Achatina acicula -/!/'«//. — Haarlass, Durlach, &c. Many 



dihgent collectors often complain that they can find 

 no living specimens of this most elegant snail, it is an 

 entirely subterraneous dweller, and must be searched 

 for under large flat stones, at the roots of planl:s, and 

 in the fissures of shale rocks. At Haarlass I found it 

 in company with Vertigo minutissima. 



54. Zua lubrica Mull. — Everywhere abundant and has existed 



many ages, as may be seen in examining the lowest 

 portions of the Loess. 



55. Z. nitens Kokeil. — (See Albers Heliceen, 2nd Ed., i860, 



p. 256.) If a species, which I doubt, it is smaller and 

 has a white lip ; according to my notes, from Sweden, 

 Baden, and Redhill, Surrey. 



56. Pupa frumentum Drap. — Haarlass, Weinheim, Durlach, 



&c. This species at first sight might be mistaken for 

 P. secale, but is larger, the shell more polished, and 

 the peristome not contracted. 



57. P. secale Drap. — Handschuhsheim, &c. 



58. P. marginata Z^r^T/). — Common; the edentulous variety 



is said to be found in some parts of the Black Forest. 



59. P. quadridens Z'/v7/. = (B. quadridens Mull.) — Langen- 



briicken. 



60. P. avena Drap. — Carlsruhe. 



61. P. umbilicata Drap. — The locality for this I am doubtful 



about. 



62. Vertigo sexdentata Flem.=^{Y. substriata, Jeffreys.) — 



Engelswiese, Handschuhsheim, and Siebenmiihlthal. 



64. V. edentula Drap. — Casdegardens. 



65. V. minutissima Hart7n. — Abundant, but local; Haarlass, 



Friedricksfelt, Biebrich, (S:c. 



66. V. pygmaea Drap. — Common. 



67. V. palustris/^/'=(V. antivertigo, Drap.) — Common. 



68. V. aipestris Albers. — Wolfsbrunnen, rare. 



69. V. Mouiinsiana Dupuy. — Siebenmiihlthal and near Frank 



fort. The latter locality by Mr. Heynemann of that 

 city.
