Ast^k®^Hra antiguensis, sp. nov* 
PI. fig. 
Co Tallinn forming large thick branches that may he more or 
less palmate* PI. figs. , represent two branches, 
natural size. The oalices are moderately deep, more or less ir- 
regular in outline, often subelliptical, the diameter varies from 
2 to 4 mm. Their margins elevated about 1 mm., a#d are distant 
from one another from 1.5 to 2.5 mm. Somewhat swollen around the 
base. The coenenchymal surface is plain. 
The septal arrangement appears often to be irregular, some- 
times two complete cycles and an incomplete third, in many calices 
the third cycle is complete, and occasionally a few members of 
the fourth cycle may be present. The absence of the smallest 
septa undoubtedly is often due to their destruction in f ossilisa- 
tion. 
Columella very poorly developed, in fact I can not be sure 
that it is present at all.
