lesser width. Even the varieties of Tereb. sphaeroidalis, some of 

 vhich are very slightly convex, are easily to be distinguished 

 from this species, because they are short and almost circular in 

 shape. The specimens found in this district are far finer than 

 those figured by E. Deslongschamps. The finest specimen from 

 the collection of Professor Buckman was beautifully figured by 

 Mr. Davidson, supplement, plate xx., figure 4. This species 

 begins in the zone of Stephan. Hurnphriesianum, but is not large 

 in it. It, however, attains its greatest size in the zone of Cosm. 

 Parkinsoni. 



Localities Bradford Abbas, Oborne, etc. (Dorset) ; Crewkerne 

 Station, Haselbury, etc. (Somerset) ; also at Dinnington, and at 

 La Provence, Languedoc, Bandol, Cuers, etc., in France, and in 

 Spain and Portugal.

This species is very rare in this district. I believe it comes 

 from the upper beds of the inferior oolite. 



Localities. Near Sherborno (Dorset), also near Cheltenham 

 ( Gloucestershire) .

This interesting species was first discovered in England by Mr. 

 J. F. Walker in the Bradford Abbas quarry, and he described it 

 in the Geological Magazine for 1878. Our English specimens 

 are about the size of figure 4, plate 65, of E. Deslongschamps
