This species agrees well with the diagnosis of the genus Capnella given by 

 KUKENTHAL, namely: "Colonie aufrecht baumformig, die nicht retractilen, un- 

 gestielten Polypen ohne Stiitzbiindel, in Lappchen stehend, dicht mit zahlreichen 

 Blattkeulen bewehrt. Canalwande dick, und dicht mit walzenformigen Spicula 

 erfullt." 



The distribution of this genus is confined to the Indo-Pacific Ocean, and three 

 species have already been described from the coast of East Africa, namely, Capnella
