with the thicker portions of the Nova Scotia coal-areas, and would 

 also give a greater probable value to the productive coal-measures. 

 In so far as these are concerned, the quality and distribution of the 

 coal would seem, as might be expected, to resemble that in tlie 

 eastern coal-fields of Cape Breton. The beds as yet found appear 

 from Mr Howley's report to be six in number, ranging from one foot 

 two inches to eight feet in thickness, three of them having over four 

 feet of good coal. The coal is apparently a free-burning bituminous 

 variety resembling that of the Cape Breton mines. 



The distribution of the beds in Cape Breton and in the Cumberland 

 coal-field and in New Brunswick has been carefully mapped on a 

 large scale by the officers of the Survey, so that any geological 

 observer now visiting the region would go with advantages altogether 

 unknown at the time of my earlier explorations. The mining indus- 

 tries have also been largely extended, the total out[)ut having increased 

 to nearly two millions of tons, and the mining villages and districts 

 having advanced greatly in population and in external appearance. 



My own work has been limited chiefly to palgeontology. In the 

 Report of the Peter Redpath Museum for 1883 will be found the 

 description of the following species from the lower Carboniferous 

 limestones of Nova Scotia and Newfoundland : — 



1. Nova Scotia. 



Discites Hart a, Dawson, [^Gyroceras Hartii, Acadian Geology] 



described from more perfect specimens. 

 Loxonema cara, S. N. 

 Pleurotomaria Acadica, S. N. 

 Sanguinolites JBrooJcJieldianus, S. N. It is nearly allied to *S'. plicatits 



of M'Coy. 

 Aviculopecten Lyelli (var. alternans). Notice of new specimens 



showing varietal forms. 

 Bermicea insueta, S. N. An encrusting Polyzoon. 

 Afegastroma laminosum, 9 v., S. N. A remarkable stromatoporoid 



form not previously known in the Carboniferous, and resembling 



some Erian and Silurian stromatoporoids, though gencrically 



distinct. 



2. NEWFOUNDLAND. 



Serpulites Miirrayi, S. N. 

 Macrocheilus Terranovicus, S. N. 

 Pteronites Gayensis (var. ornatus). 

 Serpulites annulatus, Dawson.
