Pisinna hipkinsi

Pisinna hipkinsi has an elongated conic shape, twice the height of its aperture, and had five and half whorls.^[2] The species measures 2.38mm, by 1.3mm.^[3] It is predominantly a pale yellow color, except for its protoconch which is dark red.^[2]

The species is similar in appearance to Pisinna impressa, but can be told apart by the absence of a subsutural incised spiral, and larger size in Pisinna hipkinsi.^[2]

The species is endemic to New Zealand.^[1] The holotype was collected by R.S. Bird in June 1951 from Spirits Bay at the far north of the Aupouri Peninsula in Northland.^[2] While originally described as being exclusively found in the far north of New Zealand, the species has since been identified as far east as the Aldermen Islands,^[4] and Snares Islands / Tini Heke, 200 km south of the South Island.^[5]
