Callyspongiidae Callyspongia plicifera (Lamarck) Spongia plicifera Lamarck, 1813: 435 Occurrence: La Parguera (Puerto Rico), 9 May 1964. Port Royal (Jamaica), cays, depth 10-25 m, 22 March 1964. : the specimen is vase-shaped, 17 cm high, 4 cm wide at the base, 9 cm wide below the pseudoscule which has a diameter of cm. The wall is about 6 mm thick, the rim of the pseudoscule is paper thin, laciniate. The outer surface is densely beset with irregular blunt tubercles. The colour in life was purple to lavender, not uniform, iridescent. The consistency was softy resilient. Primary and secondary reticulations of the ectosomal skeleton are not everywhere clearly distin- guishable. The primary fibres are up to 80 [xm thick, but many of the secondary ones almost reach this thickness. The resulting meshes are mostly rounded, 90 to 180 ^m wide. The embedded spicules are stron- gyles measuring 70-90 \xm. by about [xm, sparse and rare. : available is only a fragment of the wall of an apparently vase-shaped sponge. The convex side is deeply grooved. The ectosomal skeleton consists of a network of main fibres 40-100 [xm thick forming meshes 350-700 [xm wide. Within them there is a secondary reticulation of fibres 10-40 [xm thick forming meshes 140-260 [xm wide. The re- ticulation of the choanosomal skeleton is irregular, with main fibres up to 120 [xm thick and connecting ones down to 8 [xm. The fibres are devoid of spicules; only rare traces are Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not per
