170 DISTRIBUTION OF PUPILLIDAE. 



quite fine and irregularly spaced, readily visible to the 

 umbilicus, less crowded on the upper whorls than on the last ; 

 the embryonic whorls smooth. Length 2.5 mm., diam. 1.6 mm., 

 height aperture 1.1 mm., width 1 mm. (Germain). 



Kilima Njaro, in upper margin of the forest at Bismarck 

 Hill, between 2700 and 2800 meters (Ch. Alluaud and R. 

 Jeannel).

 (2), vol. 6, June, 1934, p. 381. 



Lauria alluaudi Germain. 



Shell subconic, formed of 6J/2 quite convex whorls, increas- 

 ing slowly, the last moderate. Suture somewhat deep, mar- 

 ginate. Aperture pyriform oval, quite angular above, the 

 margins converging very little and quite remote, with a strong 

 projecting lamellar parietal tooth and a very small supra- 

 parietal nodosity. Peristome slightly thick (the thickening 

 more accentuated in the middle of the outer margin) ; colu- 

 mellar margin dilated. The shell is yellowish chestnut; 

 sculptured with longitudinal oblique unequal striae, quite 

 strong but not lamellar. Length 3 to 3.25 mm., diam. max, 

 1.5 to 1.7 mm.; height aperture 1.3 to 1.5 mm. (Germain) . 



Mt. Kinangop, alpine prairies at 3100 meters (Ch. Alluaud 

 and R. Jeannel).

The shell is umbilicate, ovate, tapering from the last whorl 

 to the obtuse apex, the lateral outlines convex ; cinnamon-buff, 

 subtranslucent, rather glossy, marked with weak, unequal lines 

 of growth. The whorls are rather weakly convex, the last 

 rounded at base, curving into the moderately large umbilicus. 

 The peristome is whitish, the outer margin becoming well ex- 

 panded in its lower part, basal margin built forward and 

 subreflected. Parietal margin bearing a very small lamella 

 situated on the right side of the middle, and extending inward 

 a short distance (about 0.4 mm.), its inner half being very 

 low. Length 3.3 mm., diam. 2 mm. ; 5^/2 whorls.
