the HortoD series of Nova Scotia and the Albert shale series of l^ew 

 Brunswick. In the supplement to Acadian Geology, 1878, they were fur- 

 ther described under the term Lower Carboniferous Coal Measures or 

 Horton series. The foreign equivalents to this series as evidenced from 

 their fossil contents and stratigraphical relations were by him supposed 

 to be as follows: — 



I. The Vespertine group of Eogers in Pennsylvania. 

 3. The Kinderhook group of Worthen in Illinois. 



3. The Marshal group of Winchell in Michigan. 



4. The Waverley Sandstone (in part) of Ohio. 



5. The Lower or False Coal measures of Virginia. 



6. The Calciferous sandstone of McLaren or Tweedian group of 

 Tate in Scotland. 



7. The Carboniferous slate and Coomhalla grits of Jukes in 

 Ireland. 



8. Tlie Culm and Culm-greywacke of Germany. 



9. The Greywacke or Lower Coal measures of the Vosges as de- 

 scribed by Schimper. 



10. The older Coal formation of the Urals as described by 

 Eichwald. 



II. The so-called Ursa stage of Heer includes this, but he has 

 united this with the Devonian beds, so that the name cannot be used 

 except for local development of these beds at Bear island, Spitzbergen. 



In the vicinity of St. John the characteristic conglomerate and asso- 

 ciated beds of the Perry formation, and their upward passage into the^ 

 grey and dark fossiliferous shales and sandstone already referred to, can 

 be well studied on Kennebecasis island. The outcrops of this formation 

 about Kennebecasis bay appear to rest upon Cambrian and Pre-Cambrian 

 rocks, but on the east side of St. John harbour an interesting outlier of 

 this Perry formation is seen, where the red conglomerates rest upon the 

 Mispeck formation, and occupy the central part of a well-defined basin of 

 Devonian rocks. This basin contains the Avhole Devonian series as at 

 present recognized in New Brunswick from the base of the system, here 

 represented by the Bloomsbury division, through the Dadoxylon sand- 

 stone and Cordaite shale, formerly known as the Little Eiver group, and 

 the Mispeck division to the Perry at the top of the whole series. Fur- 

 ther west in the eastern part of Passamaquoddy bay the red beds of the- 

 Perry rest unconformably upon slaty and igneous rocks which are known 

 as the Mascarene series, the other members of the Devonian being ap- 

 parently absent along this part of the coast. From the contained fossils^ 

 it is possible that the Mascarene series may represent transition beds^ 

 between the upper Silurian and the lower Devonian.
