Corallum with the calicle subelliptical ; the ratio of tlie axes as 

 100 : 166; the summits of the small axis a little reentrant and more 

 elevated than those of the large axis, which are rounded. Columella 

 oblong, reduced. Septa very close, very little thickened externally 

 and becoming very thin Anthin, with the faces covered with numerous, 

 very tine grains, disposed in series parallel to the edge. Pali very 

 thin, covered with extremely prominent grains, with the internal edge 

 a little flexuous. — (Edw. and Ilaime).

The genera referred to this group are distinguised by the entire 

 absence of pali, and generally by the very open appearance of the 

 chambers between the septa. It includes two groups, or sub-families, 

 already referred to on page 536 : the TxrbhiolitKV, in which there is 

 no epitheca and the calicles are generally circular ; and Flahellhice, in 

 which the wall is completely covered by a pelicle-like epitheca, and 

 in which the calicles are usually elliptical. 



Desmophyllum. Ehrenberg. 

 Desmophyllum Ehrenberg, Corall. des rothen Meeres, p. 75. 1834; Edw. and Haime; 

 Ann. des Sci. nat., ix, p. 252, 1848; Coralliaires, ii, p. 76, 1857. 



Corallum simple, elevated, attached by an encrusting base. Wall 

 naked, usually smooth below and costate or crested near the summit. 

 Calicle very deep at center, without a columella. Septa broad, much 

 exsert, generally curved outward. 



This genus includes several living species from the West Indies ; 

 Mediterranean ; Atlantic coasts of Europe ; Japan ; and the following 

 from South America. It also occurs in the Miocene of southern 

 Europe. 



Desmophyllum Cum.ingii Rdw. and Haime. 



BesmophyUum Cumingii Edw. and Haime, Ann. des Sci. nat., 3© ser., ix. p. 254, Pi. 

 7, fig. 11, 1848; Coralliaries, ii, p. 77, 1857. 



This species differs from D. cristagalli in this that it is much less 

 elongated, and fixed by a large and scarcely curved base. Ratio of
