Sycon munitum Jenkin, 1908

Jenkin (1908: 442) extensively described three specimens of this species from Zanzibar. It is characterized by having both tri- and tetractines in the tubar skeleton and the brushes of diactines at the distal cones are long and relatively thin. For details of spicules size one is referred to Jenkin’s excellent description. The species is also reported from the South Arabian coast by Burton (1959), cf. above.
