From the Northern slope of Mount Easton , on a hearing of 290 deg. (mag.) 
and a distance of 3 miles from the Thomson-] or dan function. 
(Nos. 383-389. Collected by Mr. William Baragwanath, jun.) 
The present collection contains:— Dicellograptus affinis T. S. Hall; 
Climacograptus tubuliferus Lap; Glossograptus fergusoni T. S. Hall, be¬ 
sides some other unidentifiable species. The fauna seems rich and would, I 
think, repay further search. 
The age of the beds is Upper Ordovician, while that of the beds imme¬ 
diately to the east, as already reported, is Silurian.
