ing corals—among others, a peculiar branching coral, frequently 
occurring in the Stamford Oolite, but as yet, I believe, unde- 
scribed. 
Beneath this is a bed of about two feet of calcareous rock, 
thinly stratified—and under all a bed (one foot thick) of ironstone, 
thickly studded with small bodies, which are either rolled pebbles 
or concretionary nodules. I am disposed to assign this and the 
overlying beds of this section to my Lower Division (EH) of the 
Northampton Sand. 
This ironstone bed is divided from the underlying blue clay of 
the Upper Lias by a zone of a fewinches of mixed material. 
I may here mention, in passing, that I obtained from this Upper 
lias Clay the new species of Crustacean described and figured by 
Mr. H. Woodward, F.G.S., in his « Fourth Report” on Fossil Crus- 
tacea in the ‘ Transactions’ of the British Association for 1868, 
and which he has done me the honour to name Peneus Sharpu. IL 
have also obtained from the same clay a very large head, some 
vertebrae, and scutal plates, of a Teleosaurus of an undetermined 
species. 
Before leaving this Kingsthorpe area, I would mention that, about 
thirty-five years ago, a shaft was sunk in search of coal, at a point 
near the summit of the high ground of Kingsthorpe (marked on the 
map witha x). <A depth of 967 feet was reached. At a depth 
of 860 feet, the blue clay of the Lower Lias was pierced, and is 
stated to have been succeeded by “80 feet of Sandstone, 12 feet of 
Red Marl, and 15 feet of Conglomerate,” which are described upon 
the same authority as ‘“‘ New Red Sandstone;” but the authority 
I believe to be unreliable upon this point. 
It will be a matter of surprise that a renewal of the attempt to 
find coal by means of this very shaft, should during the past year 
(1869) have been urged in the ‘ Mining Journal’ and in a local 
newspaper, by a Mr. Ruglin, of Mexborough, near Sheffield, and that 
people should have been found who were disposed to listen to his 
suggestions.

In the area of Northampton, there is only one small spot (7) at 
which the Limestone of the Great Oolite (A) occurs ; and it has been 
here preserved in consequence of a slight double or triple fault, which 
let down, some 5 or 6 feet below its normal level, a patch about 
55 feet in diameter*, The whole area was afterwards planed over 
by denudation ; and this remnant of the general bed of limestone was 
alone left, inlaid, as it were, in its underlying clay. This curious 
fact was only disclosed in November last, when, in the process of 
levelling land at the back of the borough goal for building-purposes, 
the following section was exposed :— 
_ * Along the brow of the escarpment of the branching valley of the Nen river 
in this area, the upper beds are very much broken up by similar small faults, 
Poued probably by the washing out of underlying soft or arenaceous
