Diagnosis. 
Zoarium irregular in form, thin. 
Zooecia mainly immersed in the zoarium, from which the 
peristomes rise abruptly. The peristomes are well raised, 
usually circular, but sometimes subelliptical, large, and 
irregularly scattered ; as a rule the apertures are at 
a medium distance apart, but in places they are at a con- 
siderable distance. 
Gonocysts small, irregular, and generally elongated at right 
angles to the zooecia.
