Madrepora squamosa, Brook, Ann. Mag. N. H. 1892, vol. x. p. 463. 
Corallum corymbose, subvasiform, about 27 cm. diameter and 13 em. high; branches 
rarely coalescent. Under surface oblique; branches 8 to 12 mm. diameter, not flattened, 
bearing numerous elongate twigs which extend horizontally, 1-5 to 3 cm. long, 6 mm. 
diameter near the base, terete and slowly tapering to a blunt apex; axial corallites scarcely 
prominent; radial corallites all immersed or subimmersed. Branches on the upper surface 
simple or subsimple near the centre of the corallum, but more divided near the periphery ; 
the central ones are 4°5 cm. long, 8 mm. diameter near the base, 4 mm. near the apex, apices 
about 1°8 em. apart. Axial corallites cylindrical, 2°5 to 3°5 mm. diameter, 15 mm. exsert, 
wall thick, star very well marked, the directive septa rarely more prominent than the others. 
Radial corallites of the central branches equal, small, labellate, with rounded lip, spreading 
almost at right angles, rarely over 1 mm. diameter and 0°75 mm. long, but becoming wider 
and subimmersed towards the base of the branches. On the marginal branches the corallites 
are much larger and more distant ; usually 2 mm. diameter, 2 mm. long, and the lips are nearly 
2mm. apart; near the apex of the twigs the corallites are scarcely so spreading as in the 
other parts, and the form is usually flattened labellate. Corallum porous; surface reticulate 
and echinulate ; wall fragile, fenestrated. The star consists of 6 moderately developed septa 
in the corallites of the outer branches, but the directives, and particularly the lower one, are 
more prominent and thicker than the others; in the corallites of the central branches the star 
is quite indistinct, often only the lower directive septum is recognizable. 
This species appears to agree closely with Dana’s figure of M. millepora, which is 
probably not the species described by Ehrenberg. The contrast between the size of the 
radial corallites on the central as compared with the peripheral branches is more marked 
than in any other species which has come under my notice.
