Acanthochiton brookesi Ashby, 1926

Ashby, E., 1926. The acanthoid chitons of New Zealand, with descriptions and figures, including several new species. Proceedings of the Malacological Society of London 17: 5‒35 [14, 15], pl. 1, figs 3a‒c (holotype), pl. 2, fig. 7 (holotype).

Holotype: MA70002 , Figure 1e , anterior valve, median valve 4, posterior valve, collected by H. Suter from Waitemata Harbour (?) , Auckland, New Zealand.

Paratype: MA72422 , anterior valve, five median valves and posterior valve, from the type (?) locality.

Remarks: There is some doubt about the locality. Ashby (1926) reported that he was given the specimens by Suter some 20 years before they were described. However, ‘mice found their way into the cabinet, destroyed many, damaged and mixed the rest; as result the localities are unreliable, but one of the three specimens of the form under description remained attached to a tablet labelled “Auckland Harbour”.’

Ashby named the species after “my friend Mr Albert E. Brookes, who so generously supplied material for this investigation”. A.E. Brookes was a keen entomologist and conchologist, who was a life member of the Conchology Section of the Auckland Institute and Museum (aka Auckland Shell Club) and its president from 1948‒1950.

C urrent name: Acanthochitona zelandica (Quoy & Gaimard, 1835) ‒ Powell (1979): 30; Spencer et al. (2016).
