‘Helicidee 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 turbinata, modica, apice obtusa; anfract. 6, convexis, 
oblique striatis et striis volventibus subtilissime decussatis; an- 
fractu ultimo ad peripheriam rotundato, antice deflexo et con- 
_ stricto, basi convexo; apertura perobliqua, lunata; peristomate 
expanso, reflexo, ad basim rectiusculo et callo vix elato instructo, 
ad umbilicum late reflexo. 
Lat. 6 lin., alt. 64 lin. 
Hab. Tanabe. 
H. japonica, H. patruelis, and the present species form a 
oup which seems aera 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) gibbosa, 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 expanso, breviter reflexo. - Albido- 
cornea. 
Lat. 64 lin., alt. 5 lin. 
Hab. '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) sphinctostoma, A. Ad. 
H. testa globoso-conica, anguste perforata; spira conoidali; anfract. 
6, convexis, oblique striatis, ultimo ad peripheriam rotundato, ad 
aperturam valde constricto; apertura perobliqua, lunata ; peri- 
stomate albilabiato, late expanso, reflexo. Lutescenti-cornea. 
Lat. 6 lin., alt. 5 lin. | 
Hab. Tago. 
A species remarkable for the constriction of the last whorl 
just behind the aperture, and with the peristome white, ex- 
panded, and reflexed.
