I saw the type in the collection of the Geological 
Society of London in January 1898 and again in October 1903* The 
usual number of cycles of septa is three; the arrangement into 
cycles does not appear perfectly regular and uniform, so Duncan 1 s 
figures must be used with a qualification* In the best pres erred 
portions there is no granulate area on the summit of the wall 
between the ends of the septa; the upper edge of the wall apparent- 
ly is acute in perfect material. Diameter of the calices 2.5 
to 4 mm.; the usual diameter is slightly less than 3 mm. The 
details of the pali could not be mads out. It is very doubtful 
if they were distinctly differentiated. 
The coral is a G on lop or a , a ramous form of Milne Edwards 
and Haime 1 s Litharaea . Two figures of the type are giren on 
pi. , figs.
