VI. MISCELLANEA. 



I. Account of certain Species of Silurian Fossils from Hobart's 

 Town, New South Wales. 



The following are the results of the examination by M. de 

 Verneuil of certain fossils collected from Mount Wellington, near 

 Hobart's Town, New South Wales. The schistose sands and car- 

 boniferous limestones appearing among compact diorite in different 

 points near Hobart's Town are often flattened by the enormous 

 pressure they have undergone, and the shell is often gone and only 

 represented by an imperfect cast. 



Productus pustulosus (Phillips.) A species closely resembling 

 P. scabriculus (Sow.), and identical with the species common in 

 the mountain limestone of Yorkshire. 



Spirifer very near S. trigonalis. It is extremely abundant in 

 the collection, and attained a large size. It has five or six ribs on 

 each side of the dorsal furrow. 



Another species of Spirifer with dichotomous ribs. 



Another species like S. undulatus (Sow.) with transverse striae 

 on the ribs. The ribs are larger and less numerous. 



Spirifer oblatus (Sow.), or Terebratulites Icevigatus (Schlo- 

 theim), like those of Vise in Belgium. 



A very large smooth Spirifer with a depression on each side of 

 the dorsal furrow between this furrow and the edge of the shell. 



A large bivalve. 



Large pectens belonging to a new species. 



A new species of Calamopora. 



The same species are found in Van Diemen's Land, and besides 

 them are a great abundance of Hetepora, Cyathophyllum, Calamo- 

 pora, Clypeaster, and Dentalium, which are rarely met with in the 

 neighbourhood of Mount Wellington. All these specimens were 

 collected in the hills of Morambiji to the south of the Blue Moun- 

 tains, and the beds containing them are partly covered as at 

 Hobart's Town with recent lignites.
