H^iVicid^ found in Japan. 463 



Very similar in general appearance to H. japonica^ Pfr., but 

 more conoidal, and with the periphery more decidedly angu- 

 late. It is also a smaller and thinner shell. 



20, Helix {Fruticicola) peculiaris, A. Ad. 



H. testa globoso-conoidali, anguste perforata, tenui, luteo-cornea ; 

 spira tui'binata, modica, apice obtusa ; anfract. 6, convexis, 

 oblique striatis et striis volventibus subtilissime decussatis ; an- 

 fractu ultimo ad peripheriam rotundato, antice deflexo et con- 

 stxicto, basi convexo ; apertura perobliqua, lunata ; peristomate 

 expanse, reflexo, ad basim rectiusculo et callo vix elato instructo, 

 ad umbilicum late reflexo.

H. japonica^ H. patruelis^ and the present species form a 

 group which seems peculiar to Japan, and which is charac- 

 terized by the conoidal form of the shell, by the base being 

 more or less flattened, and by the straight horizontal basal 

 portion of the peritreme. To this section may be assigned 

 the name Satsuma. 



21. Helix [Fruticicola) gihhosa^ A. Ad. 



H. testa depresso-globosa, tenui, perforata ; spira parva, conoidali, 

 apice acuta ; anfract. 6, convexiusculis, striis incrementi et vol- 

 ventibus minutis decussatis; anfractu penultimo gibboso, ultimo 

 subinflato ad peripheriam rotundato, antice deflexo; apertura 

 obliqua, lunata ; peristomate expanse, breviter reflexo. Albido- 

 cornea.

Hah. Tanabe. 



A species remarkable for the sudden deflection of the last 

 whorl anteriorly, which produces a gibbose appearance of the 

 penultimate whorl. The peristome on the left side is broadly 

 reflexed, and nearly covers the umbilicus. 



22. Helix [Fruticicola) spMnctostoma^ A. Ad. 



H. testa globoso-conica, anguste perforata ; spira conoidali ; anfract. 

 6, convexis, oblique striatis, ultimo ad peripheriam rotundato, ad 

 aperturam valde constrieto ; apertura perobliqua, lunata ; peri- 

 stomate albilabiato, late expanse, reflexo. Lutescenti-cornea. 



Lat. 6 lin., alt. 5 lin. 



Hah. Tago. 



A species remarkable for the constriction of the last whorl 

 just behind the aperture, and with the peristome white, ex- 

 panded, and reflexed.
