be very small, becoming gradually broader towards the columella, or they 



may slope down with a faint bend and than descend perpendicularly downwards.

Both specimens consist of a single branch. The method of branching is very characteristic 

 The corallites are all situated in the same plane. Budding takes place near the calicular margin, 

 every corallite forming only one new corallite, and at the colony as a whole the alternatin^ 

 buds are formed to the right and lelt. In that way the- colony seems to consist of a zigzag 

 stem with the calicles at the corners. Every separate corallite is about 1 cm. long and the 

 distance hetween the calicular margin of the mother-corallite and the base of the daughter- 

 corallite is 2 mm.. 



The ril.s are low, covered with few, fine, irregularly scattered granulations. The inter- 

 costal furrows are perforated and shallow, so that the iil>s are not very 

 apparent. The calicle is 6.5 4.5 mm. wide. 



The septa are prominently exsert, those of the first cycle more protrudin- 



than those ■>! the second cycle. The arrangement is shown in the diagram
