wall of tlie sponge, the netted structure of the inner mass is apparent; 
the meshes of this net are at first small and almost the same size, while 
beneath these they are found to be larger and less regular, and mostly 
produced by radiating branches which resemble pretty well the shape of some 
species of Fenestella. (PI. II, Pig. 1^».) 
I have not seen any spicules in it. 
Locality. — This species has been found in a dark grey argillaceous 
limestone on the banks of the Murriimbidgee, near Tass. As one of the 
specimens is associated with Leptcena nohilis, McCoy, it is impossible to have 
any doubt as to its Devonian age.

Coral with flat or slightly convex surface, made up of thin layers, often 
directly superimposed. Corallites with confluent septal-costal rays almost 
e.qual to one another, sometimes slightly sinuous and continuous, to the 
number of twenty-eight to thirty-Wo, directly from one individual to 
another. Calicinal cup well marked, surrounded by a projecting ridge, and 
possessing a rather thin columella extending to the level of the surrounding 
ridge. 
Dimensions. — Diameter of the corallites, ten to twelve millimetres; 
that of the ridge, five or six millimetres. 
Horizon and Localities. — This species has been collected by E. 
de Verneuil in the Devonian of Wisconsin (United States) ; it is probable 
that the two specimens found by Mr. Clarke at Cope’s Gully, near Hanging 
Dock, in the leads, also belong to this formation.
