LIMICOLARIA, N.-E. AFRICA. 275 



A member of the group of L. ruppelliana, distinguished 

 by the absence of color flames, the shell being dark ochra- 

 ceous, and by the strong wide and regular riblets, decussated 

 by an infinite number of fine spiral lines. 



41. L. RUPPELLIANA (Pfeiffer). PL 28, figs. 32, 33, 34. 

 Shell umbilicate, ovate, very minutely granulose; whitish, 



painted with longitudinal, undulating rufous flames. Whorls 

 6, slightly convex, the last one swollen, slightly longer than 

 the spire, somewhat compressed basally; suture crenulate. 

 Aperture subauriform, the peristome thin, columellar mar- 

 gin straightened, broadly reflexed, half covering the umbil- 

 icus. Length 53, diam. 34, aperture 29x14.5 mm. (P/r.).

Quite distinct by its short spire and obese shape. Figures 

 31, 32 are copied from Kobelt's illustrations of one of the 

 original lot collected by Riippel. Another example of the 

 same lot has been figured by Jickeli (pi. 28, fig. 34).

Shell narrowly perforate, oblong-conic, compact, thin, 

 white under a thin yellow cuticle, variegated with many 

 longitudinal, almost straight, streaks of rich chestnut, rather 

 close and narrow, but with a few broad ones among them, 

 the latter often wedge-shaped, wider below ; the streaks neither 

 branching nor zigzag. On the last whorl the longitudinal 

 markings are, to a great extent, coalescent or smeared to- 

 gether below the periphery, the darker color predominating 

 on the base. Sculpture: close and fine costulse stronger be- 

 low the suture, cut into oblong granules by spiral impressed 

 lines; the decussation fine and regular on the spire; but 

 below the spirals become less regular, and disappear on the 

 latter part of the body-whorl and are wanting on the base,
