Chondrosia collectrix; De Laubenfels 1936: 183, pl. 20 fig. 1; De Laubenfels 1950: 135, fig. 60; Wiedenmayer 1977: 189, pl. 42 fig. 7; Alcolado 1980: 6; Van Soest 1981: 7; Rützler 1986: 125, pl. 5; Pulitzer-Finali 1986: 99; Rützler et al.2000: 234; Moraes 2011: 106, with several unnumbered figs; Muricy et al.2011: 52 (with additional Brazilian records).

Material examined. RMNH. Por. 9338, French Guyana, ‘Luymes’ GuyanaShelf Expedition, station 14, 6.7333°N 52.75°W, depth 76 m, bottom muddy calcareous sand, 26 August 1970; RMNHPor. 9933, Guyana, ‘Luymes’ GuyanaShelf Expedition, station 63, 7.5833°N 57.0667°W, depth 71 m, sandy bottom, 31 August 1970; RMNHPor. 9992, Suriname, ‘ Snellius O.C.P.S.’ GuyanaShelf Expedition, station E66, 7.1°N 56.1783°W, depth 65 m, Agassiz trawl, 13 May 1966.
Description. Massive sponges with smooth-shiny surface ( Fig. 4a). Largest specimen 7 x 5 x 1 cm. Color (in alcohol) grey-brown or blackish grey, mottled with lighter and darker patches. Noapparent oscules (presumably constricted in preservation). Consistency firm, incompressible. Choanosome ( Fig. 4b) featureless, densely collagenous with few canals and lacunae. In cross section the upper 1–2 mmis 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. GuyanaShelf, throughout the Greater Caribbean and NE Brazil, from the tidemark down to 76 mdepth (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 Chondrosiain the Central WestAtlantic.
