Original Description
Shell papillate, with distinct collar stricture. Length of the three joints = 3: 6: 6, breadth = 3: 8: 10. Cephalis subpherical, with a pyramidal horn of the same length. Thorax tuberculate, nearly hemispherical, with circular pores of very different sizes. From the margin of its wide open mouth descend four stout perradial ribs, which are forked at the distal end, and by communication of their fork-branches form the four large, pentagonal holes of the abdomen. From the middle of the lower margin of the holes descend four parallel, vertical, slender feet, about as long as the shell. This species is dedicated to the memory of the great Reformer, Martin Luther.

Length of the three joints, a 30, b 60, c 60µm; breadth, a 30, b 80, c 100µm.
