Original description: Radial proportion of the four spheres = 1: 2: 4: 5. Outer cortical shell thick walled, densely covered with innumerable bristle-shaped radial spines, half as long as the radius. Pores regular, circular, double-edged, of the same breadth as the bars; ten to twelve on the radius. The thick outer shell is so dark, that the outlines only of the other three shells can be seen.
Remarks on original description: Haeckel listed Cromyomma villosum under the subgeneric name Cromyommetta, but did not include the subgeneric name in the species name.[comment from RadWorld database]
