Descriptions and remarks
Diagnosis: Roughly circular openings occurring on a fourfold of nearly parallel, slightly divergent rows. The rows form an angle of 20° at most, while the openings maintain a regular distance and are situated more or less opposite each other along the length axis; the distance between the holes is approximately an order of magnitude greater than their diameter.
