This well-known Madeiran coral is in the collection ; and the 

 speciman shows calices with eight, nine, and ten septa. 



The range of the species is considerable ; for it was found by 

 Pourtales on the other side of the Atlantic.

The corallum is short, compressed in the direction of its length 

 somewhat, with an eUiptical deep calice, a broad, flat, attached base, 

 and a small, very deeply-seated, elongate trabecular columella, flat 

 on its surface, and united to the septa by six small processes. The 

 epitheca is dense, reaches close up to the calicular margin, and 

 ends there in a definite linear ridge. The septa are in six systems ; and 

 in four of them there are five cycles, whilst in the others there are 

 three cycles and one half of the fourth, the septa of the higher order 

 being developed between the primary and tertiary septa only. The 

 laminae are stout, very granular, and subspinulose, and more ragged, 

 even on the edges, curved above, where they occupy much space 

 on the edge of the calice, and dipping down suddenly on all sides of 

 the large, elongate, and deep axial space. The septa are very
