The recent genera Carpentaria, Gray, Poly- 

 trema, Gray, Rwpertia, Jones, etc., are distin- 

 guished by their extremely irregular, usually 

 attached, coarsely perforated tests, which occa-

 contain agglutinated, sandy, or other foreign 

 particles. Thalamopora, Roem., occurring in 

 the Cretaceous, probably also belongs to this 

 family. ,
