PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [April 22, 



associate it rather with that of Ogwell. The slates on either side 

 of the Teign estuary are Devonian, and apparently they rise from 

 beneath the limestone ; but there is much difficulty in ascertaining 

 this with certainty. They are entirely argillaceous, and in part red 

 or claret- coloured, and are altered by the igneous rock at Colway 

 Cross, which seems to rest upon them. 



The fossils of these limestones are so well known by the lists of 

 Phillips*, Grodwin- Austen t, and Sedgwick and Murchison^:, that it 

 is not necessary to enumerate them here. In the subjoined Table 

 will be found the local distribution of the species which have been 

 hitherto met with in the slates which immediately underlie these 

 upper Hmestones of the south- east of Devon ; but it is very far from 

 complete, as the several localities, as well as some others not men- 

 tioned, have not by any means been thoroughly searched. The 

 species from the vicinity of East and West Ogwell are given on the 

 authority of Mr. Godwin- Austen § ; the rest are from the 'Palaeozoic 

 Fossils' of Professor Phillips, and other sources ||.

11 This Table must be taken in connexion with Table III, which gives the dis- 

 tribution of species in the corresponding rocks in a difFerent area, and together 

 include, I believe, all the recorded species on tliis horizon.
