M. late foliata, frondibus crassis, margine lobatis et totidem profunde 

 subdigitatis ; supra, conos crassos subacutos undique ferentibus ; infra 

 super fide plant! . Corallum infra brevissime caliculatum; supra cali- 

 culis valde confertis, labellatis, labello elongato et fere erecto, subcom- 

 planato ; stettd obsolete!, duabus lamellis vix latioribus. 



Broad foliate, fronds stout, lobed at margin, and sometimes deeply 

 subdigitate; above, covered with short and stout subacute cones; 

 below, surface plane. Corallum below having very short calicles ; 

 above, calicles much crowded, labellate, lip elongate, nearly erect, 

 and almost flat; star obsolete, two of the lamellae scarcely broader.

The short stout cones rudimentary branchlets that cover the 

 surface of this foliate Madrepore, and its long-lipped erect calicles, at 

 once distinguish it. The cones average an inch in height, and are 

 half to three-fourths of an inch broad at base ; but a few are two 

 inches high and an inch at base. The calicles above are long and 

 crowded. One frond in the Expedition collections measures twenty 

 inches by twelve, and is over an inch and a half thick where stoutest, 

 and half an inch or nearly so at margin ; the plate is but a fragment 

 of the complete zoophyte. Another specimen is a single lobe, four- 

 teen inches long, two to three inches wide, and one and a quarter 

 thick.
