These beds contain comminuted remains of land plants, and inipressions that 

 bear a strong resemblance to Fucoidcs cauda-galli. With these are associated, 

 among other species, Strophomena hlainvilli, Rcnssclaeria ovoides, two undetermined 

 species of Choneies, Spirifera gaspensis,Lcptocoelia flabcllites, Avicula woodwardi^z.\-\6. 

 Granimysia verncuili. I'he beds to the northeast of these, along the southwest 

 side of Gaspe harbor and bay, as already indicated, are upwards of 4000 feet 

 higher in the series. They contain a few interrupted bands of a red color near the 

 top, some of them with casts of shrinkage cracks ; and along the strike, between 

 Pointe Lourde and Cape Haldimand, some of the best characterized specimens 

 of the land plants of the formation are to be obtained. In the upper 760 feet, 

 eight beds are seen to be marked by the vertical rootlets of Psilophyton ; and on 

 one of these, 200 of the rootlets were counted in a square of 6 inches. 



Sir William Dawson described the flora of these beds in detail' With 

 this we are not here specially concerned, but we may take note in passing 

 that Dawson subdivided the series of Gaspe sandstones into three parts : 

 a lower division embracing the beds at Little Gaspe and Gaspe Basin, 

 coordinated with the Oriskany and Onondaga divisions ; a middle division 

 including the sandstones of Bois Brule and Cape Oiseau {aitx Os ; on 

 modern English maps Ozo) equivalent to the Hamilton group and an 

 upper division represented by the outcrops of Long Cove and conceived to 

 be the equivalent of the Chemung group. This is a somewhat arbitrary 

 subdivision apparently based upon the distribution of the terrestrial flora 

 found in the rocks and the author distinctly states his interpretation of 

 the Gaspe sandstones as a whole as the equivalent of the entire Devonic 

 system in its more westerly representation. Most of these plant remains 

 were derived from near Tar Point on the south shore of Gaspe Bay and 

 on the north shore from Little Gaspe west. 



It is the marine fauna of these sandstones that chiefly interests us, 

 best represented at or near the locality mentioned by Logan, which lies 

 back of the first mountain at Gaspe Basin on the portage road crossing 

 from the upper basin to I'Anse au Cousins on the Dartmouth river. In 

 traversing this mountain along the old portage trail through the Avoods 

 the direction of which is for the first part nearly at right angles to the 

 portage road, one finds fossiliferous blocks all of a highly weathered cal-
