Prince Edward Island (Busk); Kerguelen (, 2S> Challenger Coll.); Southern Ocean, 3397 m. (Kluge); off East Africa? 1668 m. (Hasenbank). In the type-specimen from Prince Edward Island (87. 179) many of the zooecia of the inner rows are fertile. The ovicell forms a very shallow cap, the edges of its two layers being all that is visible in frontal view. It occupies the full width of the distal end of the zooecium between the pointed distal corners. In the inner series pointed corners are only present, on fertile zooecia, the non-fertile zooecia having a rounded end. Busk's figure (pi. x, fig. 2a) shows five fertile zooecia and one non-fertile zooecium.
