504 ZOOPHYTES. 



19. MANOPORA EROSA. (Dana.) 



M. glomerato-ramosa, erecta, caulibus subangulosis, crassis, acervate, 

 tuberculosis, erosis, obtusis. Corattum kve ; cellis immersis, undique 

 ad apicem usque sparsis, stella 6-radiatd. 



Glomerato-ramose, erect, stems subangular, stout, acervately tuber- 

 culous, erose, obtuse. Corallum without papillae, cells immersed, 

 every where scattered, even at the summits; star 6-rayed. 



Plate 46, fig. 5, corallum, natural size; 5 a, vertical section, en- 

 larged. 



Feejee Islands. Exp. Exp. 



A rudely glomerato-ramose species growing in thick clumps, con- 

 tracting and enlarging irregularly, and with a very uneven surface, 

 porous, but not at all spinulous. The cell has a flaring aperture, and 

 the star is situated rather deep within. 



It resembles the spumosa in its massive mode of branching, but 

 differs widely in not being spinulous. The specimen in the collec- 

 tions is six inches high and five broad, with the stems one-third of an 

 inch to two or three inches through. It is incrusting below, but 

 hardly foliaceous. 



IV. Cellis coralli immersis, superficie non spinuloso-asperd, sed crassl papillosd,, aut 

 verrucosa aut longl rugosd. 



20. MANOPORA CAPITATA. (Dana.) 



M. cespitoso-ramosa, ramis -1" crassis, scepe irregulariter inflatis seu 

 nodosis, et coalitis, apice rotundatis vel capitatis. Corallum undique 

 usque ad apicem confertim papillosum, papillis oblongis, 4-1"' crassis, 

 obtusis; cellis immersis, minutis. 



Cespitoso-ramose, branches to 1 inch thick, often irregularly inflated 

 or nodose, and very frequently coalescing, rounded at apex or capi- 

 tate. Corallum every where crowded ly papillose, even at apex, 

 papillae oblong, to 1 line thick, obtuse ; cells immersed, minute.
