27. MADREPORA CEREALIS. (Lamarck.} 



M. late cespitosa, paulum convexa ; supra, ramulis numerosis erectis spi- 

 ciformibus, 34'" crassis et 2" longis, proliferis et non teretibus. Co- 

 rallum caliculo apicali prominulo, parvulo (vix }'"} ; lateralibus 

 appressis, subtubiformibus in&qualibus, 1-1^'" longis, subrostratis, 

 extus sublevibus, aperturd elliptica, stelld brevissima aut subconspicua, 

 duabus lamettis paulo prominulioribus. 



Broad cespitose, somewhat convex; above, branchlets numerous, 

 erect, spiciform, 3 to 4 lines thick, and 2 inches long, proliferous, 

 and not terete. Corallum having the apical calicles a little promi- 

 nent, small (scarcely y of a line) ; the lateral, appressed subtubi- 

 form, unequal, 1 to 1 lines long, subrostrate, exterior smooth, aper- 

 ture elliptical, star very short or imperfectly distinct ; two of the 

 lamellae a little prominent.

This species has the habit of the plantaginea, but is smaller in its 

 calicles, apical as well as lateral. The branchlets are very unevenly 

 covered with calicles, some of which are long and proliferous. The 

 specimen in the collections is five inches high and six in diameter ; 

 and the branchlets above are about a fourth of an inch thick : it is 

 not complanate below ; but this may be owing to its not being full 

 grown. 



In another specimen, from the same locality, apparently this spe- 

 cies, the short calicles, low on the branchlets, have extremely minute 

 cells, while in the above, they are about a third of a line in diameter.

28. MADREPORA ACERVATA. (Dana.)
