connecting processes, which, on account of their arched or angulated form, their being 
celluliferous, and their occasionally becoming modified into stems, remove it from the 
genus (Fenestella), m which it has hitherto been placed. It differs from Polypora, 
M‘Coy, equally as regards the connecting processes; also in the serial arrangement of 
the cellules. I am not aware of the existence of any other species but the one 
following.

Diagnosis—A. funnel-shaped, multi-foliaceous Synocladia, springing from a small 
root. boliations more or less folded and convoluted. Stems somewhat strong, often 
dividing. Cellules in from three to five furrows. Dividing ridges with the (?) gemmu- 
liferous vesicles alternating with the cellule-apertures. ranches or connecting processes 
in general angulated midway between two adjoining stems ; furnished, for the most 
part, with two rows of cellules; and occasionally becoming modified into stems 
or ribs. 
This beautiful Coral is often found attaining a large size, but rarely in a complete 
state, owing to its foliations readily separating from each other: what is generally 
seen is only one frond belonging to a single individual. It varies somewhat in a few 
of its characters ; as in the width of the stem-interstices, the greater or less divarication 
of the stems producing a corresponding change in the meshes: when the stems are 
close to each other, the connecting branches or processes lose their normal character, 
passing across the interspaces obliquely or horizontally; and where they are much 
separated from each other, the branches become converted into stems. When the 
branches, forming a consecutive set, are modified in this manner, they offer a striking
