The non spicutar skeleton of the genus Merlia may be absent and a new species, M. deficiens, is described. A part of the recent Porifera may be the descendent of fossil calcified organisms (Stromatoporoids, Chaetetids... ) which have lost their calcareous skeleton. Size cells packed in cavities of the skeleton are similar to gemrnular cells, a fact which may explain the occurrence of discontinuities in the skeleton of some Stromatoporoid fossils.
