382 GREAT SERPENTINE BELT OF NEW SOUTH WALES, vii., 



ment, so that the form of the Cffinosteuni is not ascertainable. 

 There are thirty-eight laminiie in the space of a centimetre, 

 joined by pillars extending across as many as fifty lamina?, in 

 some instances. The lamina? and pillars together form a recti- 

 linear meshwork. There are about thirty-five pillars in a centi- 

 metre. No zooidal tubes are recognisable, but there are numer- 

 ous Caunopora-tubes, about 0*25 mm. in diameter, with infuii- 

 dibuliform tabulae. This form is extremely like A. clathratmn 

 Nich., and especially that variety of the species which occurs in 

 the Middle Devonian rocks of Germany. This latter species has 

 also been recognised by Professor Nicholson in the Devonian 

 rocks of Western Australia. Until the publication of his Mono- 

 graph (25), it was usually considered to be Stromatopora concen- 

 trica Goldfuss. The specimen here described as A. austraJe may 

 •come from the Loomberah limestone, but it is more probable that 

 it was found in Portion 163 of the Parish of Nemingha, "Beedle's 

 Freehold," in the Nemingha limestone.]
