MADEEPORARIA OF THE DEEP SEA. 239 



Caryophyllia CALVERi, nobis. (Trans. Zool. Soc. vol. viii. p. 316.) 



This beautiful coral was not figured in the former description of the deep-sea corals, 

 as the specimen was mislaid; it has fortunately been found, and has been compared 

 with its nearest ally, Caryophyllia antiUarum, Pourtales (Zool. Results of Hassler 

 Exped. i. p. 34j. Both have a thick wall, and exsert primary and secondary costse ; 

 but the Barbadian form has them less so than the other, and its costae are more 

 developed. Probably they are races of the same species. One specimen, -^ inch, 

 exhibits beautiful costae, subequal, granular, and flat. (Plate XLIII. figs. 15-27.) 



Genus Bathycyathus. 

 Bathycyathus minor, sp. nov. (Plate XLV. figs. 1-4.) 



A small coral, adherent by a broad base to the costse of a dead Bathycyathus 

 atlanticus, nobis, has a circular calice, four cycles of septa, some of which are exsert, 

 but all are largest at the costal ends. The costae are very small inferiorly and 

 granular. They increase in size as the form expands near the widely open calice. 



The columella is small, and the pali are thin and long. 



Height T^ inch ; breadth of calice | inch. 



Bathycyathus minor, the young coral. (Plate XLV. figs. 7-9.) 



This is a coral on the septum of an old Bathycyathus ; and it is about yj,- inch broad. 

 It has a broad base, which slopes to the calice, the wall being low, and the six primary 

 septa exsert. 



The calice is open, and there are six primaries and six secondaries and a small 

 columella. 



A coral more advanced in growth is on the stem of a larger form ; the septa are 

 numerous, and the pali are irregularly distributed. (See the Plate.) 



Genus Paracyathus. 

 Paracyathus insignis, sp. nov. (Plate XLIV. figs. 1-3.) 



The corallum is attached by a moderate-sized base, above which there is a slight 

 constriction ; the general shape is conico-cylindrical, bent and with a widely open 

 calice. The costse are distinct to the base, are subequal, and each is multigranular. 

 The calice is elliptical and open. The columella is very small, being composed of a few 

 minute processes, and it occupies about one fifth of the calice. The septa are shghtly 

 exsert, largely granular laterally, and are moderately crowded. There are four perfect 

 cycles in each of the six systems, and sometimes orders of the fifth cycle in some. The 

 orders of the fourth and fifth cycles tend to approach the intermediate septa towards 

 the inner margin and close to the pali. The septa are short, and reach inwards accord-
