Summary

(1) Reasons are given for believing that the holotype of Anthracomya adamsi Salter (the genotype of Anthracomya) has been correctly identified.

(2) It is shown that the horizon of this presumed holotype is near the middle of the Similis-Pulchra Zone, and is near if not identical with the horizon of A. hindi Wright.

(3) Anthracomya adamsi at that horizon has no close connection with A. modiolaris (from which it may, however, have been derived at a lower horizon). The distinction of these two forms is discussed, and it is suggested that among well preserved specimens only very occasional variants cause any difficulty in identification. The shells referred to A. adamsi. s. lat. by Weir and Leitch from the base of the Similis-Pulchra Zone (1936) are not considered in this paper.

(4) The relations of A. adamsi, A. hindi and A. warei are briefly discussed: in view of the limited distribution of the various species it is thought best for the present to retain the three specific names.
