CURRENT TAXONOMIC STATUS. — Pila . Valid species.

TYPE SPECIMEN. — Lectotype (here designated) MNHN 4478 .

REMARKS

The original label says “type”. A subsequent label says “ holotype ” and indicates that the specimen was figured as “pl. 4 fig. 10”, that is, in the later publication ( Germain 1907). The labels also indicate that the shell is from the expedition material of Lacoin on which the original description was partly based. The shell is indeed that figured; it corresponds in size and the damaged outline of the peristome can be seen clearly. Although, the original description was based on more than one specimen and does not include an illustration, we designate this specimen as the lectotype to stabilise the name.
