Shell oval, sub-depressed, yellowish-white, front slope very, side slopes slightly convex, posterior slope slightly concave, much so below the apex, which is placed at about 6/7 of the total length, and has a whorl on the right side. Sculpture consisting of numerous radiating riblets about 116 in number, with a smaller one in the majority of the interstices; they are crossed by thin concentric ridges, forming beads on the riblets. Slit-fasciole rather deep, with numerous lamellae crossing it. Slit long 2, large 0,33 mm., its margins thickened interiorly, a flattened rib runs towards the apex. Interior smooth, yellowish, margin crenulated, with slightly raised sides. Long. 7 mm, lat. 5,5 mm, alt. 3,5 mm.

Resembling the figure of E. bellula Adams, in PILSBRY'S monograph (Man. of Conch.) but the apex is placed more central, the slit-fasciole is not punctured etc. I am however not quite certain, that this species of simple characters has not been described, but have failed, even with the assistance of Mr. E. A. SMITH, to identify it with any known species.

8.4 to 18.3 mm in length. Most shells around 9-10 mm in length.
RANGE
The holotype was collected in the Sulu Archipelago by the Siboga expedition. In the Philippines, apart from the type, collected off Olango Island, Bohol, Balicasag Island, Mactan Island and Cebu, Oslob. The species lives between 10 to 450 m deep, most shells are from around 100 to 450 m deep.
