of this much disturbed band, while an outcrop at Malignant 
Brook to the south of the “Igneous” rocks of the coast section 
may be its eastern termination. Veins of iron ore occur in this 
series. 
Carboniferous series. I have already referred to this isolated 
series when describing the other isolated conglomerates at 
Malignant Cove, in the Section IIL 
We have two fossiliferous silurian series, both of which are 
very defective. Next the Mountain we have B’ and C, A. B., 
are wanting as well as C.D. and E. Next the shore (N) we 
have A.B; B’ C.C’ D. E., are wanting. Farther up Doctor's 
Brook on the rising ground south of Arisaig Pier, we have D. 
and E., (?) with C possibly underlying as well as B’ 
The arrangement of the two series is synclinal. 
A. occurs at Dector’s Brook and in Section III. Cove to the 
Westward. In the latter it is very complete and characteristic, 
dithologically and paleeontologically. The lowest part next sea 
is argillaceous, the next is arenaceous, the third is argiil-aren- 
aceous, and respectively—have fauna, characteristic, ]st—orthis 
and athyris; 2nd — trilobites, cyclonema crebristriata, stro- 
phomena corrugata, petraia; 3rd—lingula, petraia. 
B. at Doctor’s Brook is characteristic in its Graptelites. At 
the Cove in its lingula at the Cove at Arisaig Pier, in its 
trilobites, corals, Xe. 
B’ C.C’ D., require no revision. I would refer to “Geology of 
Arisaig,” Quart. Jour. Geol. &e., 1864. E. at its junction with D. 
in section is characteristic in its fawna, there as well as in 
McAra’s Brook and McAdam’s Brook, its litholology is distinetive. 
The only part of this Typical Series that calls for special Re- 
vision 1s A. and B., with associate rocks (a.) When my collections 
were examined by Mr. Salter and Sir R. I. Murchison in 1862, 
T had not discovered the bed of graptolites in the lower part of 
B. at Doetor’s Brook, consequently these were not taken into 
consideration when A was correlated with the “ May Hill Sand- 
stone.” I have no doubt that Sir R. I. Murchison would have 
considered the Diprionidean graptolites as of Lower Silurian 
age and have regarded B as of that age and consequently A as
