Material examined. RMNH Por. 9816, Guyana, ‘Luymes’ Guyana Shelf Expedition, station 68, 7.4167°N 57.1333°W, depth 51 m, muddy sand bottom, 31 August 1970GoogleMaps  ; RMNH Por. 10538, Suriname, ‘ Snellius O.C.P.S. ’ Guyana Shelf Expedition, station E66, 7.1°N 56.178°W, depth 65 m, Agassiz trawl, 10 May 1966GoogleMaps  .

Description. Thinly encrusting smooth sponge ( Fig. 3View FIGURE 3 a), dark brown in alcohol, 6 x 5 cm in lateral expansion, thickness 2–4 mm. Consistency firm, slippery surface.

Choanosome. Cartilaginous, with an interior skeleton of scattered spherasters, concentrated at the surface.

Spicules. Spherasters ( Fig. 3View FIGURE 3 b), with small irregular spines on the apices of the conical rays, diameter 21– 27.6 –33 µm.

Distribution and ecology. Guyana Shelf, widespread throughout the Caribbean and NE Brazil, in mangroves, on reefs, and on sandy mud, 0.5–65 m (previously down to 51 m).

Remarks. The details provided here match those of the descriptions in Rützler et al. (2007a). The species was previously known in the region as Chondrilla nucula ( Schmidt, 1862)  , but this is now considered to be restricted to the Mediterranean. Two ecological forma’s were distinguished by Duran & Rützler (2008), but as infrasubspecific units these names are not available in the sense of the ICZN. Subsequently, Rützler et al. (2007a) renamed the Caribbean species as C. caribensis  .
