LOWER CHALK—BEDFORD AND BUCKS. 
191 
The Belemnite mails are again to lie seen in the chalk-pit at 
Ash well, but do not present any features of a special character, 
except that the lower bed is a greenish-grey marly chalk passing 
down into rather rough white chalk. 
List of Fossils from the Lower Chalk of Bedfordshire 
and Hertfordshire. 
In the following list the localities are indicated by letters in 
each column, and these localities are: — 
f Totternhoe quarries (t). 
Bedford- | The railway cutting at Chalton, north of Luton (c). 
shire, j The quarry by the railway near Leagrave (1) 
l A quarry south-west of Sundon (s). 
I The quarries at Arlesey, near Hitchin (a). 
Herts. * The other quarries near Hitchin (h).

The fossils from Chalton cutting were collected by Mr. J. Saunders, of 
Luton, and were named by me. (See his paper in Geol. Mag., Dec. 3, Vol. 
VII., p. 126, 1890.) 
Those from Arlesey and other quarries near Hitchin are in the collection 
of Mr. W. Hill, and most of them were identified by me, but the fish have 
been examined and named by Mr. E. T. Newton. 
Those from the other localities were principally collected by Mr. J. Rhodes 
for the Geological Survey, and were named by Messrs. Sharman and Newton.
