Taxonomy

The species was originally identified by the name Eatoniella (Cerostraca) bathami, named after Betty Batham who assisted Ponder during his stay at the Portobello Marine Laboratory.[2]

Description

Eatoniella bathamae has a small conical shell, smooth except for the presence of faint growth lines. It has a variable colour, typically dark grey-purple, but including pale grey and yellowish-white. The holotype specimen measured 1.42mm by 0.8mm.[2]

Distribution

The species is endemic to New Zealand.[1] The holotype of the species was collected on 5 September 1963 at Little Papanui Beach, Dunedin, by Ponder himself, who identified the species on gelatinous red algae.[3] In addition to Otago, specimens have been identified on the Snares Islands / Tini Heke,[4] Stewart Island[5] and the Auckland Islands.[6]
