tliird, but a little narrower and less exsert, with the edges still more 

 rough and lacerated. The wall is thin, usually covered nearly and 

 sometimes quite to the summit wdth an epitheca, which is tliickly 

 encrusted below, l)ut usually has a distinct, thin upper edge, above 

 this the wall is usually feebly costate, the costai and outer edges of 

 septa roughly granulous or denticulate. In a vertical section the 

 septa are roughly granulous, and perforated near the inner margin with 

 irregular, rounded openings ; the dissepiments are few and confined 

 to the basal portion, irregular, and quite oblique. In a transverse 

 section near the base the interseptal chambers are divided by two or 

 three of the oblique dissepiments. 



One of the largest specimens is "63 of an inch broad ; -25 high to 

 edge of cup; the primary septa -06 exsert ; the cup -12 deep; the 

 columella '10 broad. Another specimen is '56 broad; •34 high, to 

 margin; the cup •26 deep ; the primary septa 'Oo exsert. An ellipti- 

 cal one is •50 by -40 in diameter ; -30 liigh ; the primary septa '06 

 exsert; the cup 'IS deep; the columella about •lO broad. The largest 

 specimen is '85 broad at base ; while the calicle is but "65 broad and 

 •20 deep.

Coralla always simple at maturity.* Calicles cup-shaped, mostly 

 circular or elliptical. Septa rather numerous, in several unequal 

 cycles, with the edges entire or nearly so, except at the inner edge, 

 which is sometimes divided into paliform teeth. One or more cycles 

 of pali in front of the septa. Interseptal chambers open from the 

 bottom. Transverse dissepiments rudimentary or wanting. 



The Turbinolidcie of Edwards and Haime, united chiefly by the 

 negative character of lacking dissepiments, do not appear to consti- 

 tute a homogeneous group. Some of the genera, like Flabellum, 

 Mhizotrochiis, Placotrochus^ etc., seem to be most nearly allied to 



* According to Mrs. Thyme (Annals and Mag. Natural History, iii. p. 449, 18")9), 

 Caryophyllia Smithii undergoes repeatedly, while still young, complete fissiparity, the 

 resulting portions becoming entirely free and circular. This remarkable observation 

 needs confirmation, however.
