are fossiliferous, as a vertebra about lin. diameter, probably 

 amphibian, was picked up by a visitor near one of the beds 

 from the material scattered in loading the railway trucks. 

 The exact spot where it occurred could not be ascertained,, 

 and although diligent search was made on several occasions 

 nothing else of the kind was found. It is, however, a very 

 fossiliferous horizon, as is shewn by the prevalence of the 

 fish-eye nodules of large size representing animal life of 

 some sort — fishes, turtles, or amphibians. The next band 

 of limestones also is the most fossiliferous of any, and it 

 immediately underlies these marls.

This No. 6 Group contains by far the most interesting 

 fossiliferous limestones. We gave them the name of the 

 "blue limestones," but they were somewhat piebald, portions 

 of the same block being pinkish grey in one part, and dark 

 blue grey in the other. The pinkish part was crowded with 

 Spirorbis, and the blue frequently one mass of shells. Some 

 of these have been examined by Mr. E. T. Newton, F.G.S., 

 of the Geological Survey, who recognized amongst thfem 

 the Anthracomya {modiola) figured by Sir R. Murchison in
