pressed, closely united to the cell above, rounded,

 Colonies forming subcircular patches of a deep red colour.

In this species the peristome is much elevated, and the 

 secondary orifice is suborbicular above, slightly com- 

 pressed or flattened at the top, and below is produced into 

 a deep notch or sinus. The surface is uniformly and 

 thickly punctured. The ovicell is generally much de- 

 pressed, and is inclosed round the edge by a narrow belt 

 of granular crust. The peristome is carried across the 

 front of it. 



"When young the cells are semitransparent and glossy ; 

 but with age the zoarium becomes coarse in appearance, 

 and of a dull whitish colour. 



A variety occurs of delicate texture, and with very 

 minute puncta ; but otherwise the species is very constant 

 in character.
