Corallum conical, with contracted liasc ; costse granulated, distinct as far 

 down as the peduncle, flat and separated by fine linear ridges. ( 'alicle circu- 

 lar, or very slightly elliptical. Septa rather thick, moderately exsert, sub- 

 equal, less densely granulated than in C. berteriana; the fourth cycle unde- 

 veloped in some of the systems. 80 as to give the general appearance of ten 

 half-systems of three cycles, with ten pali. Columella papillar, of the type 

 of ' '. cylindracea, not much developed. 1 [eight 2 cm., diameter 12 mm. It he- 

 longs to the same division of Caryophyllia as (', cylindracea, hut differs from 

 the latter by its thin pali, very unlike the thick pillar-like ones of the fossil 

 species, — a character of which the European specimens described by Dr. Dun- 

 can seem all to partake more or less.

A few specimens were dredged in 65 fathoms off the island of Juan Fer- 

 nandez; being immature, they agree as well with the description of B. 

 chilensis as with this one. It would not be surprising if the two species 

 ultimately proved to he mere varieties of one and the same.

Corallum attached liy a large base, al b! cylindrical when young, conical 



when old. Costa? flat, distinct to the base, granulated. Fossa deep. Calicle 

 subelliptical, the border nearlj in one plane. Septa in six systems and live 

 cycles. The primaries and secondaries subequal and somewhat exsert, spotted 

 with brown. Twelve thin pali Columella deep-seated and variable, coat-
