Lot size: 1.
Habitat: have been collected from rocks, bottles, and old shells.
Other: One of those stated in the description to bear catalog number 53856 or 53857, and once cataloged as a neotype. As a result of a loss of the original specimens in the post, they were replaced, according to the description. Loss of the first ones is immaterial to the status of these specimens -- which are not neotypes because the ostensible holotype and paratype were never cataloged or published..
