CURRENT TAXONOMIC STATUS. — Pila . Valid species.

TYPE SPECIMEN.— Lectotype (here designated) MNHN 4614 .

REMARKS

The shell is close to the dimensions given in the original description (height 39.5 mm, not 42 mm; width 35 mm, not 36 mm). The MNHN is the only place Bourguignat’s Tanzanian material is likely to be, and the label is in Bourguignat’s hand and in the purplish ink that was highly characteristic of him. Pain (1963: 154) stated that “the type” was in the MNHN but gave no additional details sufficient to (albeit inadvertently) designate a lectotype.To stabilise the name we designate this specimen as the lectotype .
