✦ Synopsis
In 1926 I recorded LonsdaIeiaj2oriformis from limestones immediately below bisulcatum-shales at Eyam, and in 1927 I published further details of the discovery, pointing out that the coral was found in situ on the dip-slope of limestones on the south-west of Mill Lane, near Eyam and about 40 feet from the lane which is almost on the unconformable junction of the Namurian shales of E2 age.
T. 0. Morris (1929, p. 65) threw some doubt on the presence of Lonsdaleia at this high level, viz., in the rubbly fossiliferous limestone of Group 5 of the vertical section, and pointed out that the statement requires modification as the Lonsdaleia Bed is in Group 2 (=D2), some 300 feet below the shale boundary. On receipt of a copy of this publication, in May 1929, I again visited Eyam and found Lonsdaleia floriformis in siru at the original locality at MU Lane, and this year (1957) during an excursion of members of the iManchester Geological Association the coral was found in sjru and in many wall-stones bounding the lane, these stones having been obtained from nearby outcrops of limestone.
