Polypsmonomorphic, arranged individually or in clusters or catkins, along surface ofbranches and/or at the tips of ultimate branches. Sclerites often dense, mainly ofspindles, clubs, and radiates. A family of about 20 genera known world-wide; at least four genera repre-sented in southern Africa. Genus Capnella Gray, 1869 Capnella Gray, 1869: 129. Utinomi, 1960: 28. Tixier-Durivault, 1966: 233.

An entire colony, 35 mm in length. B. A single polyp showing palisade-like arrangement of sclerites to form a permanent calyx; diameter of base of calyx = 2 mm. C. Sclerites from the calyx and surface of polyparium. D. Sclerites from surface of stalk. C-D. Scale = 0,6 mm. 330 ANNALS OF THE SOUTH AFRICAN MUSEUM Diagnosis Colonies often arborescent, usually with multiply branched polypariumarising from a prominent stalk. Polyps in clusters, curved inward, without crownand points arranged en chevron. Sclerites scattered throughout polyps. Polypsclerites include leaf-clubs and thorny spindles. Stalk sclerites include leaf-clubsand thorny spindles. Stalk sclerites are often irregular and compact radiate-likestructures, frequently thorny. A genus of perhaps 19 species, primarily Indo-Pacific and extending into thesouth-eastern Atlantic (Cape of Good Hope Peninsula). Typ
