Pterocyclos miriensis Godwin-Austen, 1915: 498, pl. 39, fig. 2, 2a-c.

Type material.

Lectotype (design. nov.) NHMUK 1903.7.1.3580/1 (Fig. 8A ). Paralectotypes NHMUK 1903.7.1.3580/2-4 (3 shells) from Miri Hills.

Godwin-Austen (1915) explicitly stated that four specimens of this taxon were obtained, the type specimen lot number was given as "No. 3580 Brit. Mus." and three specimens were transferred to the Indian Museum. However, currently there are four specimens in lot NHMUK 1903.7.1.3580, so it is presumed that none were sent to the NZSI. Without any explicit holotype designation or equivalent expression, these four specimens are syntypes. The specimen figured in the original description that corresponds to the shell measurements given is hereby designated as the lectotype (NHMUK 1903.7.1.3580/1; Fig. 8A ) to stabilize the name.
