This is probably a mere variety of A. ringens L., characterized by 

 its strong keel, strong sculpture and large foramen in the lip ; but 

 these characters vary widely among specimens of A. ringens. Reeve's 

 indifferent figures are copied on my plate.

Subgenus STROPHOCHEILUS. 

 S. PUDICUS (Miiller). PI. 17, figs. 39, 40. 



Pfeiffer identified H. pudica Mull, with the species I have named 

 erythrosoma, and reversing the usage of former authors, he calls the 

 shell long known as B. pudicus, B. almeida. As the reasons for a 

 different course are not given in vol. x, it may be best to re-open the 

 question here. I give on plate 17 copies of Chemnitz's figures of 

 Miiller's type. Mailer's diagnosis and description are as follows : 



"Helix pudica. Helix testa oblonga, rugulosa, rosacea, apertura 

 edentula ; labro dilatato, candido. Long 20 lin. lat. 9 lin. 



" Testa ovato-acuminata, nitida ex candido & roseo mixta, rugulis 

 minutissimis ubique vestita. Anfractus vix sex, extimus quinis vicino 

 & reliquis simul sumtis major. Faux alba; apertura ovato-oblonga ; 

 labrum adnatum roseo flavescens. Centrum axis sub labro perfor- 

 atum. In Museum Spengleriano." 



The italics are rny own, and call attention to characters the white 

 lip and nearly 6 whorls which show the original H. pudica to be 

 different from S. erythrosoma. In erythrosoma the largest specimens 

 have only 4f , while smaller shells, the size indicated by Miiller, have 

 but 4J, and the contour of the shell is wider. Chemnitz's figure of 

 Muller's type, from Spengler's collection, shows 5 whorls, and his 

 description gives " only six." The upper whorl being planorboid in 

 Strophocheilus, does not show in a front view. It will be noticed that
