two feet thick, and yet from one quarry, of which we give the 

 section, it has yielded the foUowing Hst of Ammonites and other 

 shells, as at present determined : — 



Ammonites concavus Modiola pUcata 



-Murchisoni Pleurotomaria convidea 



- Parkinson! granulata 



-subradiatus intermedia 



-Sowerbii^ -armata 



-Browni j Rostellaria subpunctata 



-Humphresianus Trigonia clavellata 



Astarte elegans <=ost^*^ 



excavata, var. Turbo Dunkein 



crassitesta pustulus 



Melania Heddingtoniensis 

 Added to these are several Ammonites and other sheUs at present 

 undetermined, and perhaps some of them as yet unnamed. 



We can also add to the Ust the following Ammonites, found 

 in the same bed in the neighhoui-hood, chiefly at Half-way 



House: — . _, „.. 



Ammonites Truellu 



■ discus 



polymorphus 



Moorii 



— Martinsii 



Now if we bring aU together the fossHs that we have found 

 in different sections, it wiU not be difficult to show that the Hst 

 would contain typical fossHs of somewhere about 200 feet of the 

 so-caUed " different zones," as we have met with them m Glou- 

 cestershire; and the interest of this thin band is heightened 

 when we consider that in it are to be found a greater number of 

 individuals of each species than are scattered about m the zones 

 to which they are in Gloucestershire locaUy peculiar. 



We have not as yet completed our list and sections so as to 

 enable us to compare the Oohtes of DorsetsWre with those of 

 Gloucestershire, but we hope hereafter to be able to do so; and 

 in the meantime it has not been thought out of place to give 

 this sUght history of a fossH as yet undiscovered in the Inferior 

 OoHtes of the latter Coimty.
