- As Trinudeum. It was figured, but not described, in the Philosophical Transactions (Vol. 20, 

 1698, p. 279, plate). 



Note. Tlie following genera are also known to occur in Victoria, Beyrichia, Cheirurus, and Sphare.v- 

 nchus (Selwyn, Quart. Jour. Geol. Soc. lSo8, XIV. pp. 533—34; Bigsby, Thesourtis, pp. 43— 4.1, 65, and 

 73, Ac; M'Coy, Smyth's Progress Sept. 1874, p. 34). From New South Wales we have Beyrichia 

 (Clarke, S. Goldjletds. p. 286). 



A species of Trinucleus, closely allied to, if not identical with, T. Caractaci, Murchison (=C. con- 

 centricus, Eaton), was discovered by the Rev. W. B. Clarke at Yarralumla, N. S. Wales (Quart. Jour. 

 IV. p. 66). 



^ Prof. M'Coy has recorded the occurrence of two new species ot Fenestella in Victorian rocks. 



4 As originally described Ceriopora contained a heterogeneous assemblage of generic types, and 

 even as now used for Palajozoic forms can only be regarded as a i)rovisional or conventional term. It is 

 probable that the majority of the latter will fall into the genus lihomhopora. Meek. 



' The genus Atrypa, with Lepfrena and Orthis, were described by l)almaii, as above, in the volume 

 for 1827, which bears 182S as its date of publication.
