MADREPORARIA OF THE DEEP SEA. 237 
III. Descriptions or New Species, AnD NoTEs ON DESCRIBED SPECIES. 
Genus CaRYOPHYLLIA. 
CARYOPHYLLIA CARPENTERI, sp. noy. (Plate XLIII. figs. 28-31.) 
The corallum is elongate, curved, and conico-cylindrical ; the calice is slightly ellip- 
tical; and there is a mark of fracture at the base, the form having been adherent. 
There is an epitheca reaching to the calicular margin, hiding the coste; and there are 
prominences on the external surface, which indicate irregular growth. ‘The septa are 
barely exsert, are narrower than the costal ends, are not crowded, and are unequal. 
There are three cycles in six systems; and the pali, which are distinct, are placed before 
the secondaries. The septal laminz, especially of the secondaries, are wavy and bent 
in their course; and the tertiaries are smaller, but well developed. The columella is 
composed of one twisted process. 
Height of corallum nearly -45 inch; diameter of calice 4; inch. 
The specimen was dredged up with Caryophyllia inskipi, nobis, in No. 9 dredging, 
2nd expedition of the ‘ Porcupine,’ from a depth of 539 fathoms. 
The base of the specimen was fractured as the coral was removed from the sea- 
floor; and the section thus shown is very remarkable. The fracture is round, and 
shows the inside of the coral, being about 35 inch in diameter. The septal number 
is nearly complete there; and two of the primaries, Nos. 1 & 4, are united by a small 
columella; and pali exist before the secondaries of the complete systems. 
This species, had it no epitheca, would evidently come within Pourtales’s genus Steno- 
cyathus (op. cit. No. iv. p. 9); and it is in the neighbourhood of my Caryophyllia ver- 
miformis (‘ Deep-sea Corals,’ p. 316). 
The generic attributes and alliances of Caryophyllia are noticed in the Deep-sea Corals 
of the first voyage of the ‘ Porcupine’ (Trans. Zool. Soc. vol. viii. pt. v. p. 309). 
CARYOPHYLLIA SIMPLEX, sp. noy. (Plate XLIII. figs. 32-34.) 
The corallum is long, bent, cylindrical, and increases in diameter towards the calice, 
which is circular in outline, and shallow. The columella is very small; the septa 
are complete in two cycles in six systems; and there are a few small septa of the 
third cycle in some systems. The primary and secondary septa are subequal, and 
extend far inwards; and the pali are like continuations of the primaries before which 
they are situated. The septa are not exsert. The epitheca is pellicular, and its orna- 
mentation is of a chevron pattern; and there are faint lines of costee, which are slightly 
prominent here and there. The base is small, and presents a fracture of former 
adhesion. 
Height 33, inch; breadth of calice 745 inch. 
Locality. No. 9 dredging, ‘Porcupine’ Expedition; with Caryophylla carpenteri, 
nobis, from which it differs in its epitheca, costa, smaller columella, and septal number.
