Holotype BMNH 1948 - 5 - 26 -415, John Murray Expedition 1933-34 station 105 off Zanzibar, 238- 293 M., 1 paratype BMNH 1948-5- 26 -414 & 1 paratype MCZ 6094, station 105.

Main Features: The holotype differs from Clark’s figure 58 in that it has 2 plates distal to the oral shield in 4 interradii, rather than 1. The marginal granules on the disc are distinct, and the surface is very granular. In the MCZ paratype, the arms are distinctly more granular than the disc. Three pairs of exposed tentacle pore, no scales.
