themselves Cymry in Wales. The name Welshman merely signifies 
foreigner, a term used by our Norman forefathers. 
The Upper Green Band Clinton (so rich in plant remains 
at Grimsby), which you may notice in the debris at the 
Incline Railway here, below Mountain View Hotel. Embedded at 
Cayuga Co., U.S., the head shield of the oldest Eurypterus 
known to me, one discovered by Mr. Townsend, of Durham Point, 
was figured and described by Whiteaves, and is in good preservation. 
It is a Guelph one. Fragments of another, which I obtained from 
the chert here, were pronounced by Mr. Billings to be doubtful 
and too imperfect for description. Where this crustacean has 
_ been since recognized in the capping of the Niagaras (Guelph sub- 
division), and below in the Clinton sub-series, the intermediate beds 
must, as I claimed formerly, surely hold specimens also, although 
unrecognized. 
A New Graptolite from the Corporation Quarry, Hamilton — 
Another new form of the above fossil has been discovered here. 
The greater part of this family group has been described and 
figured from fragments, and the base is almost unknown In this 
one, the Radix (root or initial point), is fortunately preserved, it is 
fibrous, not bulbous, as in Inocaulis. It will come, probably, as 
regards Genera, under the head Nov. Sp., Dictyonema (Hall). 
“ Supposed New Fossils, Niagara Chert-Sil., Hamilton, Ont.— 
The Chairman, Col. Grant, produced for the inspection of the section 
a remarkably well preserved Graptolite, recently obtained from the 
Corporation Quarry, expressing his opinion that it belongs to the 
new Genera of Dr. Spencer, F. G. S., F. G. S. A., Acanthograptus, 
Nov. Species of the family first discovered at Hamilton, Ont. He 
also showed a very beautiful flint-flake fossil from the glaciated beds, 
stating it may be either a Cornulites, a shelly sea worm, or a 
Pteropod, not unlike the modern Zheca. He was unable to find 
anything figured or described by Ur. Hall or others, like it, so 
probably it may be new to science. Another flint-flake fossil diffi- 
cult to determine from the state of fossilization, 1s a Pfilodictya 
(usually supposed to be a Chetzetes or Monticulipora), the pores of 
which are displayed in one specimen. The beautiful Aryazoon, 
Sagenella Elegans (Hall) was lately found for the first time here by 
Mr. A. E. Walker.”
