120 GASTROCOPTA, AFRICA. 



1 ' In form and color it brings to mind P. klunzmgeri, but is 

 distinguished from this at once by the second tooth on the 

 parietal wall, the second columellar, and the third palatal 

 plica, also by the narrower umbilicus and the fine striation" 

 (Jickeli) . 



It may be related to B. didymodonta and the Japanese 

 species. I have not seen it. 



Subgenus GASTROCOPTA (see page 53). 



66. GASTROCOPTA KLUNZINGERI (Jickeli). PL 22, fig. 3. 



Shell rimate, cylindrically ovate, whitish, diaphanous, 

 under a lens strongly, arcuately ribbed, covered with dirt. 

 Spire slightly tapering, the apex a little obtuse. Whorls 5, 

 inflated, the last somewhat compressed basally, unisulcate; 

 suture deep. Aperture semiovate, 5-folded: one high pari- 

 etal fold, parted by a median sinus, the back part higher; 

 one strong columellar fold; two palatal plicae, the second 

 larger; one acute tooth at the base of the aperture. Peristome 

 reflected, a little expanded, white, the margins joined by a 

 thin callous. Length 2*4, diam. li/4, aperture alt. 1, width 

 % mm. (Jickeli} . 



Abyssinia: Prov. Hamaszen, on the road from Genda to 

 Asmara, on the tableland of Rora-Beit-Andu ; Mekerka, on the

The thread-like striae and unusually convex whorls are con- 

 spicuous external marks of this species. In an obliquely basal 

 view the parietal and angular lamellae are seen to form a con- 

 tinuous lamella, the angular rising in a lobe where it over- 

 rides the anterior end of the parietal, and tapering forwards. 

 The inner end of the parietal lamella curves noticeably 

 towards the periphery; a character noted also in G. mimula, 

 G. damarica, and possibly to be found in other African Gas-
