8. Three Miles East of Churchill River. 



Pentamerus (Sp. Undt.) Three casts of the ventral valve of a rather 

 finely-ribbed Pentamerus in some respects like P. occidentalis 

 Hall, from the G-uelph limestone of Elora and Hespeler, Ont. 



9. Gillam's Island, Nelson Eiver. 



Atrypa reticularis, Linnseus. Two specimens. Upper Silurian or 

 Devonian. 



10. Walker's Island, Oxford Lake. 



Atrypa reticularis, Linnaeus. Five detached specimens, four with very 

 fine ribs and one with remarkably coarse ones. Matrix a pale 

 brick-red colour, just like that from the last locality. 



11. York Factory. (Loose.) 



Cyathophyllum Davidsoni, Milne-Edwards. (=Acervularia profunda, 

 Hall.) One characteristic but much worn specimen. 



Favosites (Sp. Indt.) A small rolled and rounded mass, of a species 

 with small corallites. 



The fossils from the last mentioned locality are certainly Devonian, 

 but they may have been drifted from some distance.
