In this species there is found a more or less well-developed 

 granular ooecial cover, which from the surrounding zooecia (or avi- 

 cularia) extends in irregular lobes over a portion of the ooecial mar- 

 gin. In two colonies (from St. 63 and 71 a) a number of the zooecia 

 are provided, besides the oral one, with another and much larger 

 avicularium, which takes up the rest of the frontal surface of the 

 zooecium. It is provided with a powerful beak, has a more or less 

 oblique position, and is distinctly visible from the frontal surface. 



Numerous colonies on ascidians, algæ, hydroids etc.
