 Concerning the Tryplasma lonsdalei, Mr. Dun remarks that 

 it is apparently a solitary form of the T. lo7isdalei-t ype, but the 

 tabulae are more irregularly and widely spaced than in the 

 normal form. The wall is thick, and there are short, septal 

 spines. The diameter of the corallite is 5 mm.
