132 NOVA SCOTIAN GEOLOGY—HONEYMAN, met 
Upper Silurian. This is its first occurrence in Nova Scotia, away 
from Arisaig. Jt appears to be a prior occurrence. 
17. Tentaculites, s. p—This isa small species like that of B, 
“Upper Arisaig,” Middle Silurian. 
19. Arthrostawros godfreyi.—This is the Cruciform organism, 
associated with Maclurea. Its obvious form is that of a Roman 
cross, not altogether straight in the body, the lower part of it 
being bent to the left. It is jointed. The number of joints is 
eleven. The ninth has two branches or arms of equal length 
proceeding from it in opposite directions. The right one has a 
tendency upward, not being altogether at right angles to, the 
straight part of the stem. The joints are compressed bead shaped, 
and are generally half an inch in diameter. The only form that 
T have seen figured, which has any thing in common with it, is 
the Arthroclema pulchella, Billings. Of this the joints are 
differently shaped, and the branches are more numerous. While 
Clema signifying a twig is sufficently appropriate as representing 
the shape of the latter, Stawros is more appropriate to the speci- 
men before us. 
The Maclurea and Arthroclema are Lower Silurian forms in 
Canada. 
Localities. 
The localities in the Moose and Bear rivers area, having fossils 
are: Ist the New Mines. 2nd the Old Mines. 38rd Beaver river 
above the bridge and at Rice’s mill. 4th the continuation of 
Rice’s mill strata, at Moose river. 5th Bear’s river midway be- 
tween the Village bridge and Victoria bridge. 
Inferences. 
We are thus led to the conclusions— 
1. That the magnetyte strata of Moose River are not newer 
than the Middle Silurian Period. 
2. That the Quartzites at Bogart’s and their eastern extension 
are of Trenton, if not Calciferous, age. 
I have already on lithological considerations, regarded the great 
quartzites of Gaspereaux River, Kings County, and their asso- 
ciated argillites as possibly of Lower Silurian age——Tvransactions 
1878-9.
