Baster had previously used fig. 2, 4, 5 and 6 in a paper in Philosophical Transactions of the Royal Society in London (1757). He used the images to prove that corallines are plants covered by polyps. In the same issue John Ellis, who was convinced that corallines where animals, strongly attacked Basters arguments. Eventualy Linnaeus convinced Baster to abandon his theory.

1 Vervoort (1946, p. 270) identified Campanularia johnstoni, name later changed to Clytia hemisphaerica
2 Heerebout (2009) 2c is a bryozoan, I think Electra pilosa
3 The red alga in fig. 1 and 2 could be Gracilaria gracilis or Cystoclonium purpureum (Herre Stegenga).
4 Vervoort (1946, p. 103) identified Tubularia larynx, name later changed to Ectopleura larynx.
5 Vervoort (1946, p. 255 and p. 258)
