3. Thin-bedded, fine-grained, blue limestone; some beds 
shaly, and all with thin shale partings. Contains many Beat- 
ricia and is the equivalent of the upper Beatricia zone at Ellis 
bay. Some limestone conglomerate is present with pebbles up 
to 2 inches in diameter, composed of dark-blue, flint-like lime- 
stone. 30 feet. 
2. Thin, irregularly-bedded, blue limestone with a little 
blue shale. Many Beatricia . 25 feet. 
1. Nodular, fine-grained, buff-coloured limestone in thin 
beds, essentially no shale. Resembles the rock of zone 2 of the 
south shore section and is correlated therewith. Forms the 
cliff on Vaurial river just above the falls. Base of the Ellis Bay 
formation. 22 feet. 
Section on the South Shore, Junction Cliff to Ellis Bay 
Ellis Bay Formation. 
12. Thin-bedded, greyish-blue, compact limestone with 
conchoidal fracture. Contains colonies with abundant individ- 
uals of Parastrophia lenticularis, P . reversa , Paleofavosites aspera , 
and other corals. 60 feet. 
11. Thin-bedded pale-blue limestone. Some layers covered 
with many Leptcena rhomboidalis and Dalmanella testudinaria. 
20 feet. 
10. Thin-bedded pale-blue limestone intergrading laterally 
with coralline limestone. Bedding decidedly undulatory. At 
the top a layer with well developed pillow structure. The zone 
approximates 7 feet in thickness, but where the reef-like masses 
rise into the zone above the thickness is at least 10 feet. Con- 
tains an abundance of Haly sites, Paleofavosites , and Lyellia. 
9. Fine-grained, well-bedded, pale-blue limestone. Con- 
tains an abundance of Schuchertella pecten, other fossils rare. 
9 feet. 
8. Nodular, shaly, blue limestone and shale. Contains 
Hormotoma gigantea , Platystrophia regularis, Beatricia un~ 
dulata, B. nodulosa , and other fossils, 
the Vaurial River section. 
Correlated with zone 3 of 
18 feet. 
7. Concealed above water, but exposures beneath water 
show it to be composed of limestone. 
12 to 15 feet.
