Burton to a level with the Bridport Sands (Toarcian) of the West 

 Cliff. It is singular, however, that the white bed with its attached 

 sandstone was found alone — not associated with other Inferior 

 Oolite beds, although the scissum bed crops out in the road above 

 (see fig. 4), near the top of the hill.

of various sorts of white, and sometimes brownish, matrix ; there 

 is a fine-grained white matrix looking like a lithographic stone, 

 and very similar to the White Jura of Wiirtemberg, or the diphya- 

 kalk of Tyrol — it has a smooth soapy feeling : there is a less 

 fine-grained white matrix which feels rough, and seems to be 

 somewhat sandy. These two sorts of stone are in fragments 

 irregularly compacted together, sometimes in larger masses, some- 

 times more or less in layers ; and with them occurs some brownish 

 stone. Of this bed there would seem to be some 3 or 4 feet ; and 

 attached, presumably to the base, 1 is a layer of about 1| to 2 feet 

 of a brown sandy rock. 



As to the position of this bed or beds, — in the B-ed Bed, about 

 the middle, there is a small amount of a brown sandy matrix. In 

 the upper part of the Bed Bed there are pieces of rock similar to the 

 less fine-grained stone enclosed in the redder matrix ; but there is 

 no trace of the rock resembling lithographic stone in any other 

 exposures than this one at the roadway. 



The evidence from fossils is poor. The help of a man with a 

 sledge-hammer was obtained, and the blocks on the beach were 

 broken. The yield was several specimens of a Nautilus? a 

 Bhynchonella like Bh. parvula, a Garantiana (difficult to identify 

 on account of condition), and a piece of a Garantiana sp. nov. with 



1 The tumbled condition prevents any opinion as to top or bottom. 



2 Probably new. It is something like Nautilus rotundus, Crick, has a 

 rapidly increasing whorl, a small (almost closed; umbilicus, and a periphery 

 becoming flattened.
