more abundantly in its central portion*. At the latter a few plants 

 have been found in shales of Upper Devonian age. The plants found 

 at Gaspe were described in my former paper, and are — 



Prototaxites Logani, Dawson. 

 Lepidodendron Graspianum, Dawson. 

 Psilopbyton princeps, Dawson. 



Psilophyton robustius, Dawson. 

 Selaginites formosus, Dawson. 

 Cordaites angustifolia, Dawson. 



The plants from Kettle Point, noticed with doubt in my former 

 paper, I may now refer to the following species : — 



Sagenaria Yeltheimiana, Goe])]pert. . | Calamites inornatus, sp. noy. 



4. New Brunswick. — The rocks' in the vicinity of the city of 

 St. John, constituting a part of the coast metamorphic series of 

 New Brunswick, have been described in the official reports of Dr. 

 Gesner and Dr. Eobb t ; and additional facts respecting their strati- 

 graphical relations, ascertained by Mr. Matthew, were stated in my 

 paper in the ' Canadian Naturalist,' already referred to. The new 

 interest attached to these beds, in consequence of the discovery of 

 their copious fossil flora, induced me to re-examine all the sections, 

 in company with Mr. Matthew, during my late visit ; and that 

 gentleman has recently extended the limits of our observations east- 

 ward in the dii^ection of Mispec. The results of these observations 

 I shall state in some detail, as the precise age of the St. John series 

 has not until now been determined. 



The oldest rocks seen in the vicinity of St. John are the so-called 

 syenites and altered slates in the ridges between the city and the 

 Kennebeckasis Eiver. These rocks are in great part gneissose, and 

 are no doubt altered sediments. They are usually of greenish 

 colours ; and in places they contain bands of dark slate and reddish 

 felsite, as well as of grey quartzite. In their upper part they 

 alternate with white and graphitic crystalline limestone, which 

 overlies them in thick beds at M'Clakeney's and Drury's Cones on 

 the Kennebeckasis, and again on the St. John side of an anticlinal 

 formed by the syenitic or gneissose rocks, at the suburb of Portland. 

 These limestones are also well seen in a railway- cutting five miles 

 to the eastward of St. John J, and at Lily Lake. Near the Kenne- 

 beckasis they are unconformably overlain by the Lower Carboni- 

 ferous conglomerate, which is coarse and of a red colour, and con- 

 tains numerous fragments of the limestone. 



At Portland the crystalhne limestone appears in a very thick bed, 

 and constitutes the ridge on which stands Fort House. Its colours 

 are white and grey, with dark graphitic laminae ; and it contains 

 occasional bands of olive-coloured shale. It dips at a very high

t At this place the limestone is penetrated by a thick vein of graphic granite, 

 holding black tourmaline ; and at Drury's Cove, not far distant, it contains dykes 

 of dark-coloured trap.
