Descriptions and remarks

Diagnosis. Pair of biogenic holes, unconnected, but situated in the same skeletal substrate. Each hole has a simple cylindrical form, oriented perpendicular to the substrate surface. Both external and internal openings are sharp and circular in outline.


Unbranched, circular.
