COENBKASH: OUNDLE. 
453 
species are Ammonites macrocephalus, Avicula echinata, Gervillia 
aviculoides, Waldheimia lagenalis, W. obovata, Echinobrissus 
clunicularis, E. orbicularis, Holectypus depressus, together with 
the usual forms of P/ioladomya, Gresslya, Myacites, &c. ; and 
these show that the beds do not differ in any particulars from 
those near Cirencester, &c. Prof. Judd mentions that Ostrea 
Jlabelloides usually forms an oyster-bed at the top of the Corn- 
brash.* 
Many fossils have been obtained by Prof. Judd in the neigh- 
bourhood of Oundle, near ChurchfieLl Lodge, Polebrook, and 
Cotterstock ; and a large series was obtained by J. F. Bentley 
and others, from the faulted inlier of Cornbrash between Stilton 
and Yaxley in Huntingdonshire. Among the more noticeable 
forms from Stilton, are Terebratula Bentleyi and T.coarctata; the 
latter being especially characteristic of the Bradford Clay. The 
fossils at this locality are exceedingly well-preserved, the bivalves 
as remarked by Prof. Judd, often retaining their pearly lustref. 
The occurrence of Cornbrash at Stowe-nine-churches has been 
mentioned. It was first observed there by Mr. Beeby Thompson. 
(See p. 398.) Avicula echinata, Pectcn vagans, Waldheimia 
obovata, and other fossils are met with. Mr. Thompson informs 
me that the Cornbrash has recently been exposed at lioade.
