Zoarium a thin ribbon-like layer of cells growing upon foreign 
bodies, or coiling itself upon its own previously formed zoaria, ulti- 
mately assuming a spiral, ramose, dendroid, or massive form. Zowcia 
slightly elongated (or distended), sometimes disposed in spiral lines, 
but rather more distended at the distal than at the proximal part of 
the cell; orifice circular, occasionally semicircular ; peristome thick ; 
front of cell finely punctured. Owctwm an enlarged globose cell, 
having beneath the orifice a semicircular cluster of punctures defi- 
nitely arranged. 
The above diagnosis, with but very slight alterations, was drawn 
up from a series of forms from different horizons: Bradford Clay, 
Forest Marble, and Cornbrash. There are some features, such as 
the ocecia, that I have not found as yet in the Richmond forms, 
otherwise the rest of the diagnosis has been checked off as descrip- 
tive of specimens in the present series. It appears to me that it 
would be advantageous to science if the name Terebellaria were 
suppressed, but, seeing that the whole of the typical features have 
been found growing upon what passes for Terebellarva of authors, 
especially from the horizons given, I have thought that it would 
answer my purpose if I just placed a [?] between brackets after the 
generic name.
