Diagnosis. 
Zoarium of long, narrow, serpuliform bands, which are irregular 
in width and rather thick. The zoarium may consist of 
a single band, or it may be slightly branched. Each band 
consists of from two to five zooecia in width. 
Zooecia mostly short, but their length is variable ; usually they 
are crowded, but in places their whole length may be seen. 
Walls transversely striate. 
Peristomes well raised ; irregularly distributed. 
Gonoecial expansions occurring as knot-shaped enlargements of 
the zoarium. «
