Original Description

The moderately large (about 160 μm), spherical to sub-spherical shell has a very rough surface, which is formed by massive frames. The small- to medium-sized, irregularly arranged pores are separated by large bars, the outer wall is rather thick. The double (?) spiral whorls of the inner shell are weak to absent and some specimens are filled only with spongy meshwork. Clusters of short polar spines can be found in some specimens. A pylome is not visible.


Etymology:
In reference to the overall resemblance of the shell’s streamlined shape and trailing spines to that of a comet or meteor (latin peregrinator – traveller).

Extra details from original publication

Occurrence. Early Miocene–Late Miocene, questionable occurrences into Pliocene.

Remarks. The absence of a clear pylome in this form means that its inclusion in this study as a prunoid is not entirely justified. However, the spiral inner shell, complete outer shell and presence, in at least some specimens, of clusters of short polar spines suggest an affinity to the other prunoids in this study. Assignment to the lithelids, however, would also be possible.
