other superior formations. It so happens that these new 

 Radiates have been found at about the same time both here 

 and abroad, though Mr. Harrison's has the priority. As the 

 Rhoetics have been generally observed to underlie the 

 Lower Lias in its course from the Somersetshire coast on 

 the S.W., to Gainsborough, in Lincolnshire on the N.E., 

 it was to be expected that they would be present in the 

 intervening tract beneath the Lias, and no doubt underlie it 

 in Nottinghamshire. Indeed they have been observed by 

 Mr. Etheridge at Elton in Nottinghamshire, East of 

 Nottingham, and lately by the Rev. A. Irving, on a new 

 line from the latter town to Melton Mowbray ; and he 

 thinks when the cutting is lowered, the section will be a 

 very extensive and interesting one.* They are known at 

 Barrow-on-Soar, North of Leicester; and Mr. L-ving notices 

 a fine section at Newark, with the usual Rhcetic fossils, but 

 no * bone bed,' and another on the roadside between Newark 

 and Leadenham.f The Rev. J. Cross informs me that they 

 are present just over the Humber, North of Brigg, in 

 Lincolnshire; they are also seen at Redcar, in Yorkshire, 

 and South-West of Carlisle, underlying the lower Lias, 

 described by Mr. Binney, some years ago. Mr. J. Plant, 

 of Leicester, has noticed ripple-marked micaceous sandstone 

 abounding in casts of PuUastra arenicola, Axinus, and 

 Modiola, in the outlier at Needwood and Bagot's Park, 

 Staffordshire. He also refers to them in a paper now pre- 

 paring on the Valley of the Soar, in Leicestershire, Their 

 detection in Leicestershire, Nottinghamshire, and in the 

 North, is of some interest, as it extends the area of this 

 group, and connects it with the Warwickshire and Lincoln-
