"The colonies are rather coarsely constructed and attain a height of up to 30 mm. The hydro- 

 caulus is wholly irregularly ramified and shows no distinct main stem. The branches proceed almost 

 rectangularly from the stem or the mother branch, but at once curve upwards, forming a very acute 

 angle or even a parallel with it. The hydrocaulus and the branches are almost entirely smooth, having 

 only here and there wrinkles slightly indicated. The strongly contractile polype, when extended,

 a scattered occurence, the totally black parts indicate a common occurence) 



attains to a length of nearly 2 mm., and then is slenderly fusiform or nearly cylindric; when contracted 

 it is oviform, oval, or almost globular. The numerous capitate tentacles are irregularly distributed 

 all over the polype. 



The gonophores develop into eumedusoids, 1.5 mm. long, with no tentacles, normally not break- 

 ing away; they have four well-developed radial canals and a circular canal. Up to three gonophores 

 occur on the polype near its base".
