this locality, on the liné of strike of these slates, in the state of Maine, 
graptolites of the age of the Llandeilo rocks were subsequently found, 
showing the extension of a band of Ordovician slates southwest into the 
state of Maine. Subsequently the same band was traced eastward 
through New Brunswick to the Baie Chaleur. Thus was established the 
existence of a belt of Ordovician rocks crossing northern Maine and New 
Brunswick, southward of the belt of Silurian (Upper) rocks discovered 
by Gesner. 
Ordovician strata were next discovered in southern New Brunswick 
at St. John, where there are beds with Arenig graptolites infolded with 
the Cambrian rocks of that place. As these beds with graptolites are an 
integral portion of the upper division of the St. John Cambrian terrain, 
it is evident that there is here a second belt of Ordovician rocks in New 
Brunswick. . 
But though we have been able to recognize two bands of these rock 
in the province above named, no Ordovician strata have yet been de- 
termined in Nova Scotia. It is true that Dr. Honeyman had claimed 
that the fossils of Wentworth Station were Lower Silurian, but this view 
was contested by Mr. Billings, who could find here nothing older than 
the Clinton Group. 
On examining the fossils sent me by Mr. Howley from Newfound- 
land, and referring to notes made some years ago on others collected in 
Cape Breton by the officers of the Geological Survey of Canada, it be- 
came evident to me that still another belt of these rocks existed along 
the Atlantic coast. This belt has remained unrecognized owing to the 
scarcity, and, in many cases, the bad condition of the fossils. 
The fossils more recent than the Cambrian in southeast Newfound- 
land, are those of Great Bell and Kelly’s Islands in Conception Bay. 
Mr. Billings described some of these many years ago, but he left unde- 
termined the generaof his species which I describe below. Under modern 
methods of determining genera, it becomes necessary to know something 
of the interiors of the Brachiopods, and as these are not described nor 
figured by Billings for the species in question, | sought from Mr. Howley 
an opportunity to examine those in the museum at St. John’s, and from 
Mr. Whiteaves, those at Ottawa. 
The declared age of the rocks containing these fossils has been 
governed by that of the adjoining and very characteristic Cambrian 
faunas (in Newfoundland, Lower Cambrian, in Cape Breton, Upper) and 
so the indications of these rare and obscure genera of Paleozoic type later 
than the Cambrian, has been overlooked. In Newfoundland, the Ordo- 
vician or Silurian rocks are, in Kelly’s Island, gray micaceous sandstones, 
and in Great Bell Island, pale gray, white-weathering, coarser sandstones, 
dipping at a low angle ; while the Cambrian rocks of the mainland ad- 
joining are shales with limestone beds and dip at a higher angle.
