As Fissuridea:

Shell small, white, elevated, reticulately sculptured; apex a little in advance of the middle of the shell, rather pointed; the anal aperture long-oval, the margins excavated in the middle, internally with a thickened margin, subtruncate behind; sculpture of radiating threads with wider deep interspaces, crossed between the apex and the base by about a dozen concentric lines, representing old margins, nodulating the radials and forming deep pits between the intersec-tions; interior of the shell white, the margin forming a regular oval, and often internally radially grooved in harmony with the external ribs. Length, 5; breadth, 3.5; height, 3 mm.
Cotypes.—In the Bermuda Museum and U. S. National Museum Cat, No. 221618.
This small species has been carefully compared with young speci-mens of the already known species with none of which could it, ap-parently, be prudently united.
