Madrepora frag ill’s, sp. n. 
Corallum shortly pedunculate, spreading horizontally, 
cespitose, delicate; branches radiating, at first round, becoming 
flattened towards margin, but never coalescing ; surface finely 
echinulate ; upper surface giving off closely long, simple, or 
proliferous calices, sinuously curved, either direct or from 
short thickened branchlets ; length of calices up to 15 millim., 
tapering very slightly, with circular aperture, with thin lip 
and six delicate septa ; under surface bare, convex, except 
for a few rather large immersed calices ; at margin a few 
branchlets, very delicate, much compressed, and proliferous. 
This is a very beautiful coral, and differs essentially from 
M. speciosa , to which it is nearest allied, by having branches 
never coalescing and the tubular calices being almost the 
same thickness throughout.
