52e. Var. HARTMANNI Martens. PI. 21, fig. 34. 



A slender form from Senaar, between Hedchat and Gere- 

 bin, to which Martens refers Ferussac's pi. 141, fig. 3. 



53. L. LONGA Pilsbry, n. sp. PI. 32, figs. 18, 19. 



Shell imperf orate, very long and slender ; Avhite with broad, 

 oblique red-chestnut stripes, which do not split above. Sur- 

 face slightly roughened by some low, irregular growth- 

 wrinkles, but without spiral stride. Whorls 9y 2 , moderately 

 convex, the last tapering downwards. Aperture rather nar- 

 rowly ovate ; columella oblique, the columellar margin widely 

 reflexed and adnate above, tapering rapidly downwards; 

 basal margin deeply arcuate. Length 74, diam. 20, length of 

 aperture 23 mm. 



British East Africa: near Magois (A. Donaldson Smith). 



"L. colorata var. fuscescens' : Marts, is a more roughly 

 sculptured shell with thicker spire. The species megalcua 

 and coulboisi of Bgt. seem to be allied. The type specimen 

 has lost its cuticle and most of the color, the stripes scarcely 

 showing except on the back of the last and penultimate 

 whorls. It may be an elongate form of a species usually of 

 more normal proportions. 



54. L. MEGAIVEA Bourguignat. PL 33, fig. 26. 



Shell covered-rimate, very much lengthened, subcylindric, 

 rather opaque, somewhat thick, obsoletely striatulate. cris- 

 pate around the suture; uniform buffish-white with sparse, 

 irregular chestnut flammules. Spire very much produced, 

 cylindraceous, slowly tapering, obtuse at the summit. Whorls 

 9, convex, slowly increasing, parted by a deep suture, the last 

 whorl convex, slightly over one-fourth the total alt. Aper- 

 ture oblique, ovate; peristome unexpanded, acute. Columella 

 moderate, reflexed, shortly curved; outer margin a little 

 arched forward ; parietal callous transparent, scarcely visible. 

 Length 60, diam. 17, aperture 17x8.5 mm. (Bgt.}.
