Material examined. RMNH. Por. 9338, French Guyana, ‘Luymes’ Guyana Shelf Expedition, station 14, 6.7333°N 52.75°W, depth 76 m, bottom muddy calcareous sand, 26 August 1970GoogleMaps  ; RMNH Por. 9933, Guyana, ‘Luymes’ Guyana Shelf Expedition, station 63, 7.5833°N 57.0667°W, depth 71 m, sandy bottom, 31 August 1970GoogleMaps  ; RMNH Por. 9992, Suriname, ‘ Snellius O.C.P.S. ’ Guyana Shelf Expedition, station E66, 7.1°N 56.1783°W, depth 65 m, Agassiz trawl, 13 May 1966GoogleMaps  .

Description. Massive sponges with smooth-shiny surface ( Fig. 4View FIGURE 4 a). Largest specimen 7 x 5 x 1 cm. Color (in alcohol) grey-brown or blackish grey, mottled with lighter and darker patches. No apparent oscules (presumably constricted in preservation). Consistency firm, incompressible. Choanosome ( Fig. 4View FIGURE 4 b) featureless, densely collagenous with few canals and lacunae. In cross section the upper 1–2 mm is usually lighter colored and presumably is the cortex (verifiable only with histology), deeper in the choanosome scattered spicule fragments and calcareous nodules are found.

Distribution and ecology. Guyana Shelf, throughout the Greater Caribbean and NE Brazil, from the tidemark down to 76 m depth (previously down to 40 m).

Remarks. The variability of this species, including several Caribbean reports of the Mediterranean Chondrosia reniformis  , is indicative of the possible existence of more than a single species of Chondrosia  in the Central West Atlantic.
