100 ME. L. M. PAESOjS'S ON THE CAEBO>^irEEOUS [vol. Ixxiii, 



The palseontological material available is yeiy poor, both in 

 quantity and in state of preservation, compared with that usually 

 obtained from normal undolomitized Kmestones of the Lonsdalia 

 sub-zone. The compilation of thefaunal list has only been possible 

 through the kind co-operation of Mr. R. Wood, whose collection 

 and help have always been at mx disposal. 



Coral structures have been preserved by dolomitic rejDlacement, 

 but all brachiopods occur as dolomite casts. Large single corals 

 are usually represented b}" imperfect specimens of which the 

 internal tabulate area has been removed ; hence definite genera 

 cannot be identified, though several mav be present. In these 

 circmnstances it seems better not to make any statement with 

 reference to genera or species that appear to be absent. 



Barrow Hill. 



South-south-east of Breedon Cloud, and at a distance of less than 

 a mile from it, a small exposure of dolomite occurs in a disused 

 quany. Formerly the rock was worked for lime, but the place is 

 now rather overgrown. The quany faces all directions in tui'n. 

 The beds on the northern side dip north-eastwards, but at the 

 southern end the dip is south-westward on account of a fault. 

 The rock consists of a dense yellow dolomite very similar to the 

 denser, poorly idiomorphic, and purer dolomite of Breedon-on- 

 the-Hill and Breedon Cloud. Xo deep-red haematite inclusions are 

 present, although particles of insoluble matter or unaltered calcite 

 give a cloudy appearance to the cr3"stals. A little limonite is 

 present. So far as I am aware, no fossils have been recorded from 

 this inlier. Most specimens observed or collected by me were in a 

 bad state of preservation, but the following may be quoted : —

Yery small exposures occur on both sides of the stream and road. 

 Only a few feet of dense yellow dolomite exhibiting slight fiexures 

 are seen, and I Avas unable to obtain any fossils.

The southernmost inlier of the district is situated quite close to 

 Charnwood Forest, and about 2^ miles south-east of Breedon Cloud. 

 The exposures are very small and particularly barren. About 

 24 feet of dark impure limestones, quite unlike the Breedon 

 yellow dolomite, somewhat thinl}' bedded and separated by thin 

 bands of shale, constitute all that is to be seen. Numerous pockets 

 in the limestone are filled with a brownish marl. The dip is about 

 10° northwards, and the limestone is faulted against the pre- 

 Cambrian on the south. The onlv fossil that I obtained was a
