On the 24th of June, 1885, a paper by me, entitled “Observations on some imperfectly known Madreporaria from the Cretaceous Formation of England,” was read at a meeting of the Geological Society which, encountering an adverse report from the referee, was with the consent of the Council, withdrawn by me, and published verbatim in the Geological Magazine of the same year (Dec. III, Vol. II, pp. 541–563, PI. XIV), 1885. The present communication is a continuation as well as a correction of the former one, which has become necessary from the acquisition of additional material.
