Description
The length of the shell is 17 mm, its width 6 mm. Marwick considered this species a direct ancestor of Phenatoma rosea to which it closely resembles in shape and ornamentation.
Distribution
This extinct marine species was endemic to New Zealand and fossils were found in fossiliferous beds of calcareous tuffs at Whenuaturu Peninsula.

gollark: They do mesh networking? Very neat.
gollark: We have a bad BT consumer router thing at home, which has a disappointing lack of graphs and indeed any status monitoring features whatsoever.
gollark: My server's status monitoring page has several hundred graphs in it, about ten of which are useful.
gollark: Hmm, graphs, those are always fun.
