The sequence here indicated, and the general character of the 
beds, so well compare with the series near Northampton, that the 
grouping above noted may on stratigmphical grounds be adopted 
with confidence. Fossils are not abundant nor well-preserved, 
but I have obtained Avicula braamburiensis, Lima, Ostrea, Pecten, 
Rhynchonetta, Crustacean remains, &c. Mr. Walford informed 
me that he had obtained casts of Trigonia signata ; and he is 
disposed to place the beds in the Upper Division of the Inferior 
Oolite.
