MADRACIS ASPERULA, Milne-Edwards and Jules Haime, 1850. 
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.

BALANOPHYLLIA BREVIS, sp. nov. (Plate VIII. figs. 9-12.) 
The corallum is short, compressed in the direction of its length 
somewhat, with an elliptical 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 
lamine 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
