Upper Lias. 



This formation constitutes a thin band of argillaceous material, 

 strongly distinguished from the underlying Middle Lias, but show- 

 ing in some localities, as over Prince Charles's Cave, gradation into 

 the superimposed Oolite. 



On the south side of Portree Harbour the following fossils were 

 obtained from the beds in Section I.

Lowee Oolite. 

 1. Inferior Oolite {Lower Series). 



Dark grey sandstone courses alternating with micaceous shaly 

 sands stained with carbon. 



The majority of the fossils were collected in the bottom bed ; but 

 Ammonites Murchisonce occurs throughout, and is abundant in brown 

 marly nodules in sandy shale, near the top of the series ; the Belem- 

 nites are also diffused, and are plentiful in the sandy beds.
