SOME years ago I published, with the late Professor T. Rupert 

 Jones, F.R.S., a description of two small Limuloids referred to 

 the genus Bellinurus, sent me by ray friend Dr. H. M. Ami (then of 

 the Canadian Geological Survey), who obtained them from the 

 LovEfiai-Carboniferous Marine Series on the Intercolonial Railway of 

 Canada, in Colchester County, JSTova Scotia (Geol. Mag., 1899, 

 pp. 387-95, PI. XV, Figs. 2 and 3), under the specific name of 

 B. grandcevus. Fig. 2 was collected from the sixth cutting east of 

 Riversdale Station and Fig. 3 from the third cutting east of Colnary 

 River. 



Dr. Ami subsequently sent me a further collection of specimens 

 made by him in 1907, from the Carboniferous Series, Glace Bay 

 Mines, Cape Breton, Nova Scotia. Before describing these, how- 

 ever, I venture to give a few notes on the country whence they 

 were obtained, taken chiefly from Dr. Ami's account of Nova Scotia.^ 



Nova Scotia, New Brunswick, and Prince Edward Island form a 

 group of provinces known as "the Maritime provinces", on the 

 eastern flank of the Dominion, and with Newfoundland represent 

 the most approximate land to our shores in North America. 

 •The peninsula of Nova Scotia, 268 miles in length, varying from 

 60 to 100 miles in width, forms a part of the ancient Acadia, being 

 connected by an isthmus with the Province of New Brunswick at 

 the head of the Bay of Fundy (well known for its high tides), its 

 main axis being from north-east to south-west, and its mountains, 

 with its appendage Cape Breton Island being, geologically, outliers 

 of the Appalachian system on the mainland to the south-west. The 

 northern limit of the Carboniferous system touches the Gulf of 

 St. Lawrence at Miscou Head, and extends in a broad band along 

 all the inner coast of Nova Scotia and into Cape Breton, and comes 

 out near Sydney upon the coast of the Atlantic, where the waves 

 wash the coal-seams on the sea-shore. Carboniferous rocks also 

 occur in the Magdalen Islands and at the south-western point of 

 Newfoundland, where a seam of coal 3 feet thick crops out near the 

 shore. 



The Island of Cape Breton is really a continuation of Nova Scotia, 

 from which it is only separated by the Strait of Canso; it is 

 108 miles long, and contains the important coal-field of Sydney, 

 which extends along the Atlantic shore for 32 miles and covers an 

 area of over 250 square miles. Thirty-four seams occur in this 

 section, but only a few of them have been worked. 



Pictou Coal-field, situated on Northumberland Strait, has the 

 finest harbour on the whole north coast of the province. Here the
