(4) Iron Veins of the Triassic Traj?. 



Veins of Magnetite and Specular Iron occur in several locali- 

 ties in the great beds of trap associated with the Triassic red 

 sandstones of the Bay of Fundy, but so far as known these ores 

 are insignificant in quantity. 



It will be observed from the above notes, that while the iroo 

 vein of the Cobequid hills is at no great distance from the coal- 

 field of Cumberland, with which it has now railway connection, 

 the still larger and more important deposits of Pictou are very 

 near to the extensive collieries of that district, and to railway and 

 water communication, so that every facility appears to exist for 

 their profitable exploration, and it may be anticipated that they 

 will soon be rendered available for the supply of iron of superior 

 quality, more especially to meet the large and increasing demand 

 of the Dominion of Canada. 



DESCRIPTIONS OF NEW FOSSILS FROM THE DE- 

 VONIAN ROCKS OF \YESTERN ONTARIO. 



By H. Alleyne Nicholson, M.D., D. Sc, M.A., F.R.S.E., 

 Professor of Natural History in University College, Toronto. 



Having been engaged for some time in studying the fossils of 

 the Corniferous Limestone of Western Ontario, I purpose in the 

 present communication to give brief descriptions of some of the 

 new forms which have come under my notice. I shall, however, 

 simply give the descriptions, without illustrations, as I am pre- 

 paring a detailed report upon the fossils of some of the Palaeozoic 

 formations of Ontario, in which the species in question will be 

 fully illustrated.
