* As the sands and clays of the Weymouth group pass insensibly into the Oxford oolite, it is 

 difficult, and perhaps unnecessary, to distinguish them by a definite boundary. The fossils 

 appear to be the same. 



t Most of the specimens here referred to, from the neighbourhood of Weymouth, are in 

 Mr. Goodhall's collection.
