I. Caliculato-ramosfe, cellis simplicibus aut paulum lobatis. 



1. MUSSA FASTIGIATA. (EUis.) Dana. 



M. fastigiata, discis< scepius suborbiculatis. Corallum ramis crassis, 

 caliculis remote costato-angulatis, non dentato-echinatis, -1" latis 

 (raro J") ; lamettis vix dentatis, apice subacutis. 



Fastigiate; disks usually nearly circular. Corallum with the branches 

 stout ; calicles remotely ribbed-angular, not dentato-echinate, to 1 

 inch broad (rarely an inch), lamellae scarcely toothed ; subacute 

 at apex. 



West Indies. .Ellis. 



This species, here based on Ellis's figure, is peculiar in having 

 pointed lamellae but sparingly notched, and the exterior of the calicles 

 angular or polygonal, without spines or teeth ; though near the Eu- 

 phyllise, it is represented with the open concave cell of a Mussa.

 Mussa capitata, Oken, op. cit. 74. is a much smaller species, and probably

Caryophyllia fastigiata, Lamarck, 2d ed. The M. fastigiata of Pallas appears to be 



ii. 355, No. 12. Two or three Euphyl- a Euphyllia (see note to page 165. Seba's 



lisa are here included. No. l,tab. 109, may be the above species.) 



2. MUSSA CARDUUS. (PoHas.} Dana. 



M. maxima, discis suborbiculatis. Corallum caliculis crassimis (2J- 

 3") elongato-turbinatis, fere orbiculatis, exlus undique valde lamelh- 

 striatis et serratis ; cella concava, margine rotundata ; lamettis crasse 

 serrato-dentatis. 



Very large; disks nearly circular. Corallum having the calicles very 

 stout (2 to 3 inches broad), very long turbinate, nearly circular; 

 exterior every where (above and below) strongly lamello-striate and
