Skeleton:
No information given by Sim & Bakus. If this is G. gibberosa then it should have a cortical layer of Sterrasters covered by a subectodermal crust of Spherasters. Chonanosome: A confused interior with dispersed Spherasters and Oxyasters.

Depth: Subtidal.
Note: Spicule drawings stylized. The Sim and Bakus material is not available for study.
