Summary

The cephalopods and stromatoporoid collected from Akpatok Island, Ungava Bay, N.W.T., in 1931, by Cox, are described by Foerste in this communication as follows:—

Endoceras coxi sp. nov., Endoceras sp. (resembling E. coxi), Endoceras akpatokense Foerste, Endoceras two spp., Shamattawaceras cf. ascoceroides Foerste and Savage, Orthoceras ungavense Foerste, Spyroceras sp. (resembling S. balteatum (Bill.) in some respects), Spyroceras cf. aquilonare Troedsson), Spyroceras wordiei Foerste, Spyroceras two spp., Huronia septata Parks, Westonoceras sp., and Beatricea undulata Billings.

Tentative correlations of the Akpatok limestones with other areas are drawn from this material. The greater part of the lime-stones appear to correlate with the Red River formation of Manitoba. The lowest horizons, containing Westonoceras, apparently correspond to part of the Nelson River formation of the Hudson Bay region; the intermediate horizon, with Shamattawaceras and Huronia, apparently to the Shamattawa formation of the same locality; while the horizon with Beatricea (650 feet above sea-level) is of Richmond age. The extent to which the remainder of the fauna, as yet identified, agrees with this is reviewed.
