Reports the occurrence in several localities on the Antrim coast of Ireland of a Gonioteuthis zone in the White Limestone (Cretaceous), occurring below the Belemnitella mucronata zone which has been considered to be the first occurrence of belemnites. It is also noted that White Limestone as low as the Marsupites testudinarius zone can be identified in several localities. The Gonioteuthis localities are described. Also considered is the question of the deposition of the White Limestone of M. testudinarius age across the area of the Highland Border ridge and it is presumed that it occurred across the northeastern end.
