Ampullaria ampullacea var. javensis Nevill, 1885. Hand List. Moll. Ind. Mus. p. 6.

Current taxonomic status.

Pila ampullacea (Linnaeus, 1758), junior synonym.

Type locality.

“Java”; Baron F. von Richthofen, leg.

Type material.

Lectotype (here designated): NZSI M.27736/6 (registered 17 December 2014 as Ampullaria (Pachylabra) ampullacea var. “subcelebensis”). Paralectotypes - the shell illustrated by Mousson (1849: pl. 9 [as "pl. 1"; error], fig. 1), location unknown; the shell illustrated by Philippi (1852 [in 1851-1852], pl. 19, fig. 3), possibly in the Museo Nacional de Historia Natural, Santiago, Chile.

Shell dimensions.

Lectotype: SH 63.1 mm, SW 57.1 mm, AH 48.8 mm, AW 34.2 mm.

Remarks.

The labels associated with the specimen in NZSI M.27736/6 identify the specimen as "var. subcelebensis", a name that has never been published; one of the labels was probably written by Nevill (Fig. 13B ). However, in his original description of Ampullaria javensis , Nevill (1885: 6) said that this was celebensis of Mousson and of Philippi (non Quoy & Gaimard) and that it had a less produced spire than true celebensis. So the name “subcelebensis” makes sense. Therefore, although Nevill (1885: 6) named his variety " Ampullaria javensis ", it seems logical to consider the specimen labelled “subcelebensis” as a syntype of Ampullaria javensis , as also discussed by Cowie (2015: 38). Cowie (2015: 38) also considered as syntypes the shells illustrated by Mousson (1849: pl. 9 [as "pl. 1"; error], fig. 1) and Philippi (1852 [in 1851-1852], pl. 19, fig. 3), which were referred to Ampullaria javensis by Nevill (1885: 6). As noted by Nevill (1885: 6), the dimensions of the NZSI specimen closely match the dimensions of the shell illustrated by Philippi (above), as does its overall shape. Cowie (2015: 38) was not completely certain that the specimen in MNHNCL is that of Philippi and could not locate that of Mousson. It seems reasonable, therefore, to designate NZSI M.27736/6 as the lectotype of Ampullaria javensis Nevill, 1885 to stabilize the association of the name with the single NZSI specimen that Nevill had to hand when he introduced the name. The specimen illustrated by Mousson (1849: pl. 9 [as "pl. 1"; error], fig. 1) and that illustrated by Philippi (1852, pl. 19, fig. 3) are then paralectotypes.
