branchlets less expanded ; the cells are usually three in a transverse 

 row, they are prominent, usually less than half immersed ; their

 and 4. 



" Zoarium constituted of short clavate branches very irreqularly 

 disposed and united by frequent anastomoses, so as to form a

 sometimes produced into rather long, straight, projecting tubes ; 

 oosecia — ? " (Busk.)
