Remarks.

Kendrick and Wilson (1975), in their valuable study on type specimens of Bothriembryon , have argued why the type locality as given by Pilsbry is unlikely; they presume that the specimen originated from Doubtful Island in the Bremer Bay area. It should be noted that this locality is ca. 170 km east from Albany, Bald Head, which is the type locality of Helix melo Quoy and Gaimard, 1832, and of their variety Helix melo castanea (see next section). Should material from these two localities prove to be sufficiently distinct for systematic separation, it is worth noting that the name castaneus Pilsbry, 1900 is a homonym of castanea Quoy and Gaimard, 1832. The material is accompanied by a label "selected as type / by Iredale 1939 / p. 19", but this is not regarded as a valid lectotype designation by Iredale.

Current systematic position.

Bothriembryontidae, Bothriembryon melo (Quoy and Gaimard, 1832).
