Current taxonomic status.

Pila angelica (Annandale, 1920), valid species.

Type locality.

“Bangkok” [Thailand]; Dr. Malcom Smith, leg.

Type material.

Syntypes: NZSI M.11649/2 (registered 10 September 1919, 2 spms).

Shell dimensions.

Syntypes: SH 72.4, 73.5 mm, SW 69.0, 69.1 mm, AH 55.0, 57.6 mm, AW 41.9, 42.6 mm, OH 49.7, 53.8 mm, OW 29.7, 30.0 mm.

Remarks.

Annandale (1920: 11, pl. 1, figs 9, 10) described and illustrated the two type specimens labelled as “type”. Cowie (2015: 29) determined that only the two specimens illustrated on pl. 1 were syntypes, despite the fact that Annandale (1920: 13) gave dimensions for three specimens and implied that he had seen several more (Code, Art. 72.4.6).
