Sj>. Char. Corallum from ono and a-lialf to two lines wide; walls of the corallites 
thickened as they bend outwards from the imaginary axis to the siir ace; ca ices ova , 
intercalated cells very numerous, sometimes one row seiiaratmg con iguous c , 
at other times three or four rows, and forming irregnlar maculie ; spines ornamenting 
the walls of the corallites few and irregularly disposed. 
Ohs The specimen consists of a small portion of a corallum, partly in 
section and partly preserved in the round. It presents all the characters of Professor 
Nicholson’s section Reterotryim* is jmarly related 
Phill. sp., especially the variety miliaria, Nicholson. Its delicate foim an 
assist in distinguishing this coral. , r o Pvmnie

Sp Char. Corallum sublobate or submassive, of cylindrical or flattened 
branches, which have a diameter of from loss than two to more than three centimetres. 
Corallites vertical, or nearly so, in the centre of the branches but finally bending ou 
ward nearly at right angles and being continued for some distance in this direc 
before reaching the surface. Corallites in the central portions of the coiMlum tfi 
walled, polygonal, and closely contiguous ; but in the horizontal portion of their c 
thickened by annular accretions, by which the tubes are placed in contact the i 
vening, uuthickened segments being free. Corallites on an average about one- 
of a millimeter in diameter ; tubes of smaller size being here and there intercalated an »
