appended to all the septa. Exotheca is present, and connects 
the costae. Septa numerous, especially in large corallites, 
where the cycles, which are small and rudimentary in the lesser, 
become well developed. In the smallest corallites there are six 
systems of four cycles, the fourth and eighth orders being very 
small# In medium-sized corallites there are six systems, four 
cycles in five systems, and in the sixth there are the rudimentary 
sixth, seventh, and eighth, orders# The first, second, and third 
orders are nearly equal in size. In the largest there are six 
systems, and from twelve to fourteen septa in every system. 
Lateral teeth exist on all the primary sepia at the place of 
greatest width# The higher orders in every system are very 
linear* Endotheca abundant, but not in excess. Columella large, 
well developed, and spongy. Coenenchyraa formed of cells produced 
by the costae and the exothecal dissepiments . 
This is the largest form of compound Astraean yet described, 
and when in mass must present a very striking appearance; unfortu- 
nately no calices have been discovered as yet* Reproduction by 
extra- calicular budding#
