Description

Shell ovate-turrite, rather solid, glossy; dirty white or buff, ornamented with longitudinal brown flames and streaks, covered with a yellowish cuticle. Spire long, the apex obtuse. Whorls 8 to 9, a little convex, obsoletely longitudinally striated, the upper ones very obsoletely decussate below the suture, the last whorl nearly two-fifths the whole length of the shell. Aperture oval; columella very arcuate; peristome acute. Alt. nearly an inch and a half. Alt.: diam. as 100:35
This is one of the narrowest species of Achatina. It has the general appearance of Limicolaria. The initial whorl and a half are smooth; then follow several very finely, densely striate whorls, the strife cut into long granules by incised spirals. This decussation usually disappears wholly from the last whorl or two, but sometimes persists just below the suture. The oblique stripes of the surface usually are abruptly replaced on the last whorl by narrower vertical streaks. Two specimens of the series before me measure: Length 36, diam. 14, apert. 15 mm., whorls 8,5.; Length 42, diam. 14.5, apert. 14 mm., whorls 9.

Distribution

West Africa: Loanda. Dr. Welwitsch reports this agate snail as of frequent occurrence on the margins of the small lakes of Quicuje (Loanda), where they bury themselves very deeply in the sand in the dry season. Large ones attain a length of 48, breadth 10 mm., with 9 whorls.
