Sp. Char . — Corallum large, ramose, spreading dicliotomously ; 
branches cylindrical or sub-compressed, from a quarter to one inch in 
diameter, decreasing in size but little towards their apices ; stratification 
usually visible only in the peripheral zone. Corallites polygonal in the 
axial region, becoming cylindrical in the peripheral area, the angle of de- 
flection being sharply marked, at times almost becoming a right angle ; 
viewed transversely the corallites are long-oval, rounded, or suh-polygonal, 
from one-third to half a millimetre in diameter. Periodical annulations 
alDsent in the axial region ; numerous, close-set, and sub-pyriform in the 
outer zone, but when this zone is mueh extended becoming confluent. 
* By Count P. de Strzelecki, S. crinita was recorded from Illawarra, in limestone (Phys. Descrip., X. S. 
Wales, 1849, p. 91) ; by Prof. F. M‘Coy from Wollongong, in sandstone, Darlington, in sandstone, and Black 
Head, Illawarra, in calcareous beds (Ann. Mag. Nat. Hist., 1847, XX, p. 226); and by Prof. J. D. Dana, at 
Wollongong Point, Illawarra (Wilkes’ U. S. Explor. Exped., Vol. X, 1849, Geology, p. 711).
