MADEEPOEAHIA OF THE DEEP SEA. 237 



III. Descriptions of New Species, and Notes on described Species. 



Genus Cartophtllia. 

 Caktophtllia caepenteri, sp. nov. (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. 

 Thei"e is an epitheca reaching to the calicular margin, hiding the costse ; 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 laminse, 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 -^ inch ; diameter of calice xu inch. 



The specimen was dredged up with CaryophyUia 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 ^ 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 CaryophyUia ver- 

 miformis (' Deep-sea Corals,' p. 316). 



The generic attributes and alliances of Caryaphyllia are noticed in the Deep-sea Corals 

 of the first voyage of the ' Porcupine' (Trans. Zool. Soc. vol. viii. pt. v. p. 309). 



Cartophtllia simplex, sp. nov. (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 oi-na- 

 mentation is of a chevron pattern ; and there are faint lines of costse, which are slightly 

 prominent here and there. The base is small, and presents a fracture of former 

 adhesion. 



Height -Yo inch ; breadth of calice ^b" inch. 



Locality. No. 9 dredging, ' Porcupine ' Expedition ; with Caryophylla carpenteri, 

 nobis, from which it differs in its epitheca, costee, smaller columella, and septal number.
