Observations. — This coral is widely distributed in the Yeringian 



t>eds of the Victorian Silurian. It differs in no way from the 



British examples from the Wenlock Limestone. The normal 



massive form of the Silurian type, as distinguished from the 



Devonian nodular and branching forms, is here recorded for the 



first time from the blue-grey limestone of Cave Hill, Lilydale. 



In the specimens now figured, which have a diameter of about 

 two inches, the corallites are curved and irregular, wit'h an 

 average diameter of 1.5mm., rather short, and with the outlines 

 four, five or six-sided. Septal spines are present, but smalt, with 

 occasionally one long projecting spine which is thicker than usual. 

 Tabulae are numerous, about 8 to 10 in 5mm. The mural pores 

 are large, irregularly and widely spaced. 



Occurrence. — Cave Hill, Lilydale (coll. F. Chapman) ; Also 

 found at Deep Creek, Thomson River ; Cowombat Creek ; Gibbo 

 River; Mitta Mitta River; Wombat Creek. Silurian (Yeringian).
