194 Fossiliferous RocJcs in Nova Scotia, 



A few notes by aiiotlier observer wlio is doav labouring in the 

 same interesting field may not be unnecessary and unacceptable. 

 A catalogue of the most interesting Silurian Sections in Nova 

 Scotia is already given in the paper referred to. To this I 

 would now add two altogether new and equally interesting local- 

 ities, -which I shall endeavour to describe, adding some observa- 

 tions upon a supposed extension of the Arisaig Section. 



The first of these localities is to the S. W. of Merigomish in the 

 county of Pictou and on the north of the Metamorphic hills that 

 extend between Barney's River and East Kiver, vide Dawson's 

 Geological map of Nova Scotia. The first and lowest part of 

 the section, as yet observed, occurs at a place where the Antigo- 

 nishe and New Glasgow new road crosses a small brook about 

 3 J miles west of Barney's River and to the east of French River 

 and about 5 or 6 miles from the Gulf of St. Lawrence. Here there is 

 a quantity of shale which is apparently very little altered, having 

 fossils in good preservation. At the side of another small brook 

 to the westward, we have similar shale with correspondeng fossils. 

 This appears to be equivalent to the Arisaig group of Clinton age, 

 as we have here the Graptolitkus Clintonensis, Strophomena 

 corrugata and a species of Orthis which is characteristic of the 

 Graptolite shale of Arisaig ; we also found a trilobite which is 

 however different from any that has been met with at Arisaig. 

 We have also fossils like those of the upper Silurian group of 

 Arisaig, abounding in the drift from French River, till near 

 Sutherland's River, where there is a small brook which is crossed 

 by the road already referred to, and which has on the one side 

 drift with Silurian fossils and on the other or northern side the 

 lower carboniferous Conglomerate. 



Among these fossils we find Homalonotus Daiosoni, Dalmania 

 Logani^ BeyricMa pustulosa^ Chonetes A^. Scotica. Chonetes tenui- 

 striata, Crania Acadiensis and other organisms characteristic of 

 the Arisaig series. 



There is thus every reason to suppose that we have here dis- 

 covered a section exactly parallel to that of Arisaig. On account 

 of its inland position we cannot have the aid of old Neptune in 

 disentombing its ancient inhabitants, so that its fauna cannot be 

 collected and studied w^ith equal advantage. It is nevertheless 

 to*be regarded as interesting on account of its similarity ; and as col- 

 lections of its organisms even under existing circumstances are by 

 no means insignificant, either in number or variety, it is possi-
