«Left valve less convex and smaller, valves diversely sculptured; right valve with solid uniformly elevated concentric laminae crossing thread-like rather distant radiating riblets; where the lamina crosses a thread, especially near the margin, it rises into a minute grooved spine; auricles similarly sculptured; surface showing the prismatic texture in a very delicate manner; left valve also prismatic, with some strong radiating sculpture on the auricles, but the body of the valve marked with fine concentric, uniform, wavelike undulations; auricles well marked, the anterior the smaller; byssal notch rather deep, fascicle narrow, close to the border of the valve. Alt. 7.0; Ion. 7.25 mm.
Obtained in 82-123 fms. at Barbados. At Station 297, where the specimens were living, the bottom was stony, and the bottom temperature 56° 5 F. This species is among the Pseudamusiums what A. cancellatum is among the Propeamusiums. It is differentiated from the following species by the characters mentioned under the latter, and appears to be always pure white. There were six strongly pigmented, proportionally very large, ocelli on the mantle-edge of the left valve. In the very young the reticulation in a concentric sense is sometimes looped, which at first gives it a different aspect. By accidents of growth the radiating sculpture and its spines are sometimes not rectilinear from the umbo, which also gives it for a moment an unfamiliar aspect.» WILLIAM HEALEY DALL, 1886
