«Shell ovate orbicular, scarcely equilateral, sub-inequivalve,. slightly convex, ornamented with about 25 rounded ribs as broad or broader than the smooth interspaces; ribs with closeset erect crescentric scales; occasionally a riblet is interposed between the primary ribs towards the front. Ears unequal, radially ridged, and transversely lamellated; of the right valve, the posterior ear triangular, obliquely truncate; anterior ear elongated with a deep byssal sinus; of the left valve, the anterior larger than the posterior with the outer margin curved, the anterior one perpendicularly truncated.
Dimensions.— Length, 45; height, 48; thickness through both valves, 12. Localities.— Chalk rock of the Bunda Cliffs, Great Australian Bight; Polyzoal rock, Aldinga Bay; at mouth of the River Onkaparinga; and at Surveyor's Point, Yorke Peninsula {R.T.). The species may appropriately be named in honour of Sir John Eyre, from the circumstance of its occurrence at Wilson Bluff, Great Australian Bight, whose graphic description of an attempt to scale this bold headland must be familiar to those who have read the narrative of his adventurous overland journey to Perth.» RALPH TATE, 1886
