A piece of honeycomb coral (Eschara foliacea) is easily found, and, when well selected and placed in the aquarium, may continue to grow there by the labors of its living infusorial tenants: they are not unworthy rivals of the Madrepores, or deep-sea coral-builders of warmer latitudes.

Eschara lichenoides, occurring in Algoa Bay.

ESCHARA, Ray. 1. E. lichenoides, M. Edwards.
