Affinities. 
The elliptical and almost Cheilostomatous shape of the zooecia in 
this ‘ species ’ is its main character. Its nearest ally is probably 
8. granulata^ from which it cannot be very sharply defined, for the 
specimen figured on PI. I. Fig. 7 is in the main a normal granulata\ 
hut the zooecia shown on the right-hand branch of that figure are 
very similar to those of S. calypso, I accept the species mainly 
owing to its retention by Pergens, and owing to the interest of the 
unusual zooecial form of its zooecia.

Diagnosis. 
Zoarium very irregular ; the branches meet to form a network. 
Walls strongly corrugated. 
Zooecia with very tall peristomes, raised almost at right angles 
to the zoarium. 
1 Spiceus, ‘ spiky,’ from spike -like prominence of the peristomes.
