East Africa: Zomba (Johnston).

"A smaller species than A. johnstoni, with a less tapering 

 and shorter spire, narrower whorls, and rather finer gran- 

 ulation. The color varies from uniform greenish-yellow t9 

 rich brown, but some specimens, chiefly of the latter variety, 

 exhibit reddish striping upon the spire. This kind of orna- 

 mentation, however, does not appear to extend to the last 

 volution" (Smith).

Shell ovate-fusiform, yellow, uniform or painted with 

 wavy or zigzag stripes of deep reddish-chestnut. Spire 

 lengthened, obtuse at the apex. Whorls 9, the upper three 

 smooth, a little convex, the rest convex, roughly granu- 

 lated with strong, oblique growth-lines and numerous spiral 

 striae, the granules almost disappearing below the middle of 

 the last whorl. Aperture small, inversely auriform, blue- 

 white, showing the stripes through. Columella lightly arcu- 

 ate or rather straight, white at the edge below, obliquely 

 truncate. Length 79, diam. 40, aperture 35 x 19 mm.

"The principal distinguishing features of this fine specieg 

 are the prolonged spire, the general form and coarse granu- 

 lation. As in some other species, two varieties of coloration 

 occur in the present form. Some are white, clothed with a 

 glossy yellowish epidermis, here and there varied with darker 

 oblique stripes, indicating periods of growth. Other ex- 

 amples, however, are adorned with more or less oblique, dark 

 reddish-brown, wavy or zigzag-like stripes, which are slen- 

 der above, becoming broader below. Those on the body- 

 whorl coalesce inferiorly and form a rich brown patch at 

 the base or anterior end. The coarse granulation practically 

 ceases at the periphery, the spiral stria? becoming less pro- 

 nounced below" (Smith).
