and must here content myself to give a general descrii^tion of 

 the Shepherd's Gutter and Brook Beds. The former, the 

 equivalent to the XummuUna Bed at Stubhington, Bracklesham, 



Shells from the Shepherd's Gutter Eed.8, 



and White-Clift' Bay, is so called from a small stream at the 

 foot of Bramble Hill Wood, about a mile due north of the 

 King's Gairn Brook. The measurements are as follows : — 

 (1) Gravel from one to five feet; (2) light-coloured . clay, with 



following interesting measurements: — (1) Beds of marl, containing Valuta 

 geminata, discovered forty years ago, at Cutwalk Hill, by Sir Charles Lyell, 

 and now re-discovered, and a small Maj-gineUa, seven feet. (2) Bed of 

 bluish sandy claj^, Avhich becomes, when weathered, excessively brown. 

 This bed, very rich in fossils, which are in a good state of preservation, is 

 equivalent to what is now called the Middle Marine Bed, at Hordle and 

 Brockenhurst, sixteen to nineteen feet. (3) Hordle Freshwater Beds, con- 

 taining two species of Polanomya, and comminuted shells, fifteen feet. (4) 

 Upper Bagshot Sands, measuring, as far as the workmen have gone, twenty 

 feet, and below Avhich lies the water at the top of the clay. The important 

 point to be noticed is the extreme thinning out of the Hordle Freshwater 

 Beds, which, from the depth of two hundred and fifty feet at Barton, have 

 here shrunk to fifteen. Mr. Prestwich has suggested that these beds, as 

 they advance in a north-easterly direction, become more marine, which seems 

 here to be confirmed.
