The genus Tricycloseris was erected by R. F. Tomes in 1878 (p. 190) for a single specimen of a compound coral obtained from a fallen block on the shore near Charmouth, Dorset. The associated fauna led him to postulate a Middle Lias age for the bed from which the block was derived. A recent examination of the specimen shows that Tomes’s diagnosis was unfortunately based on a complete misconception of the coral—what he termed the “upper surface” is actually the under surface, and what he referred to as the “under surface” is, in reality, the calicular surface
