Catalog entries: Spongodictyon

Original description: Liosphærida forming a sphere of spongy framework, which encloses in the centre a double latticed concentric medullary shell.
Remarks on original description: The genus Spongodictyon can be regarded as a Thecosphaera, in which the simple latticed cortical shell is represented by an irregular spongy framework, which immediately encloses the double latticed medullary shell. Sometimes this latter appears triple, the inner surface of the spongy cortical shell forming a smooth spherical lattice plate, separated by an interval from the double medullary shell.

[By referring back to p.459 in his monograph of 1862, Haeckel in 1887a obviously meant Spongodictyon to be an emendation of the name Spongodictyum, which is unjustified according to the provisions of ICZN (1961) art. 33a. Spongdictyon is thus a junior objective synonym of Spongodictyum Haeckel, 1862]
