Scale: 2 cm. are from 4 to 10 [im thick and form meshes 50-80 | wide. The choanosomal skeleton is a reticulation of plurispicular fibres 23-37 (im thick (spongin not overlapping), only occasionally joined by thinner fibres. The spicules are oxeas measuring 90-95 x jim. : The specimen is erect, subcylindrical, giving off three digitate processes tapering to a sharp point. The surface is conulose, harsh to the touch. The consistency is resilient. The colour in life was grey to buff; it is light brown in spirit. The ectosomal reticulation is made by primary spongin fibres about 45 p,m thick, entirely filled by spicules, forming meshes about 450 | wide, secondary fibres about 28 firn thick, cored by several spicules, forming meshes about 280 (im wide, tertiary fibres about 10 Jim thick, mostly cored by a single spicule in cross section, forming meshes about 60 {im wide. The spicules are oxeas measuring 80-88 x p,m. Callyspongia reticulata (Keller) (Fig. 72) Siphonochalina reticulata Keller, 1889: 382 Occurrence: Wasin Channel (04°39'S - 39°'E), depth 25 m, diver, 23 January 1972. The specimen is claviform, cm high, cm in diameter, with wide apical vent. The surface is conulose, with obtuse conules about 5 mm apart, about 3 mm high. The consistency in the dry state is firmly.
