Distribution

This top snail is endemic to the southern shores of New Zealand. C. turneri has been found around Stewart Island (including Ulva Island in Paterson Inlet) and has also been recorded on the Snares, Auckland, and Campbell Islands further south.^[3] It inhabits the low intertidal to shallow subtidal zone, where it lives on seaweed-covered rocks near low tide level^[3]. The holotype was collected under such conditions at Stewart Island.^[2]
