DISTRIBUTION OP PUPILLIDAE. 171 



Belgian Congo: Camp Lukumi, Mt. Karisimbi (north of 

 Lake Kivn), at 11,370 ft., in moss in the subalpine heather 

 zone. Type 77267 M. C. Z., coll. by Dr. Jos. Bequaert. 



By the wide removal of the angular lamella towards the 

 middle of the parietal margin, from its usual position near 

 the posterior angle, this species resembled L. horhonensis Pils. 

 and L. desiderata Preston (vol. 27, p. 62). It appears to be 

 closely related to the latter, which occurred on Mt. Kenya at 

 9,000 to 10,000 ft., but it differs by the very small size of the 

 angular lamella, which is more reduced than in any other 

 Lauria, and by the less oblique columella margin. I have not 

 been able to compare a specimen of L. desiderata, but its 

 habitat is remote from that of our species. The relatively 

 large umbilicus of L. karisimliensis is one of its notable 

 features. 



L. bequaerti Pils (this vol., p. 138) is very different, being 

 larger with a strongly developed angular lamella connected 

 with the outer lip. L. alluaudi according to the description 

 •differs by possessing a strong tooth on the parietal wall, and 

 it has one turn more in a shell of the same or smaller size. 



Truncatellina flavogilva Germain. 



Shell subcylindric, the spire formed of 7 quite convex whorls 

 •of regular increase, the penult very convex, developed in 

 width, the last moderate, suture deep. Summit obtuse, flat- 

 tened. Almost no umbilicus at the bottom of a funnel-shaped 

 cavity. Aperture semioval, but little oblique, not toothed, 

 the separated margins joined by an inconspicuous callus. 

 Peristome white, thick, slightly reflected, the columellar 

 margin obliquely arched, white. The shell is a little grayish 

 yellowish. Embryonic whorls very finely striate, the others 

 -sculptured with oblique, subundulating and very close longi- 

 tudinal riblets. Length 1.5 mm. (Germain) . 



Massif of Kilima Njaro: Neu Moschi, a post on the Rau 

 river at the foot of the south slope of the mountain, at 800 

 meters (Ch. Alluaud and R. Jeannel).
