Elonichthys browni. 



E. elegantulus. 



E. ellsi (Lambe). 



Though by some geologists it has been claimed that the 

 Albert series and the correlated Horton series of Nova 

 Scotia are of Devonian age yet the palaeontological evidence 

 indicates that they are of Carboniferous age as pointed 

 out by Lambe [6] in the following words. 



"There is a great similarity between the fishes of Albert 



mine and those described by Dr. Ramsay Traquair 



from the Calciferous Sandstone series of Scotland; they 

 belong to the same genera, but differ as to species. The 

 genera of Palaeoniscidae ; Rhadinichthys, Elonichthys, 



and Canoblus have been considered to be typical of 



the Carboniferous age". 



From the Albert series have been recovered several 

 species of plants. These include " Aneimites acadiens and 

 Lepidodendron corrugatum, the characteristic and omni- 

 present species of the Horton group, to which the Albert 

 series belongs."* 



The strata of the Albert series are exposed in the vicinity 

 of Albert Mines and at other localities to the east and west. 

 In some of these places the strata are comparatively un- 

 disturbed and lie with low angles of dip ranging in value 

 between 5° and 30°. In the Albert Mines area, however, 

 the strata form a rather tightly compressed anticlinal fold, 

 and in places are vertical. At this locality they are uncon- 

 formably overlain by division two of the Intermediate 

 group. 



The Albert series is of especial importance since it is 

 from the sandstone members of this series that the petro- 

 leum and natural gas of the Stony Creek field (situated a 

 few miles north of Hillsborough) are derived. The Albert 

 series, with the same general characters as at Albert Mines, 

 is exposed over a few detached areas extending east from 

 Albert Mines for about 15 miles (25 km.). The same strata 

 outcrop at intervals for about 25 miiles (40 km.) to the 

 west of Albert Mines and there occur along the northern 

 slopes of Caledonia mountain. The Albert series has been
