. Bulletins of American paleontology. Alaskan Bajocian ammonites: A\' 379. Text-figs. 16a, b. Cross-section (X ) and septal suture (X at D = 65 mm.) of Erycitoidcs profundus, sp. nov.; holotype, totally septate, from loc. L1067 in t!ie Middle E. /lozvelli Zone of Wide Bay (PI. 59. fig. 1). and the largesit fragment of a body chamber measures 70 mm. in height and width at the aperture, corresponding to a diameter of the conch of approximately 220 mm. Body chambers are poorly preserved (mainly locality A 86). The secondaries increase in fre- quency (36-38) more than the primaries (12-13) so that there are regularly three secondaries per primary. The secondaries are more narrowly spaced than in E. lioiveUi, and project increasingly though moderately, decreasing the intercostae angle to 130°-150°. The ventral smooth zone remains narrow. The keel becomes obsolete only near the aperture. The left half of an aperture with peristome is well preserved on an internal mold of a fragmentary body chamber probably be- longing to this species (PI. 60, fig. 1). The strong oblique constric- tion cuts off three secondaries under an angle of approximately 45^. The peristome is sinuous with a broad "\entral" lappet and re- traction as in E.
