74 THE HAMILTON ASSOCIATION. 
NOLES ON AChE Wis OSSilles: 
Since the publication of ‘‘ Number XVI Journal and _ Pro- 
ceedings’? I obtained a better specimen of the Cornulites 
therein figured which has been submitted to an expert for his 
examination. If it proves to be a new species, as I believe it 
to be, I suggested the name 7heca Niagarensis may be appro- 
priate. 
I have also to call the attention of the Section to some 
remarkably fine graptolites from the city quarries recently 
obtained. ‘The Dictyonema from blue building beds, Niagara, 
seems new. A portion of the top branch was noticed by Mr. 
Nichol who put the flag aside for me, and I succeeded in 
developing it subsequently with the chisel. The other grapto- 
lite came from the lower part of the chert, barren of this class 
hitherto as we considered. 
The Orthis (Winona lake shore) was named O. Carlugi 
(Hall) but on comparison with Salter’s figure of Orthis retrorso, 
the identity appeared so clear I referred to Schuchert’s work 
on the Brachtopods and ascertained the correctness of this view. 
It has not been mentioned as a Hamilton drift fossil, but has 
been found in Canadian Hudson River or Trenton rocks else- 
where. 
Among the fossils obtained last summer at Winona Lake 
Shore, Ontario, was one I put aside for your inspection at the 
last meeting of the Section, but unfortunately it got mislaid 
and ‘was not in the parcel whose contents you examined. It 
represented a species of Grammysia probably and occurred in 
Cambro-Silurian drift. The name was first applied (Gramma) 
a lime and Mya (Mussel) to a Devonian Lamelibranch in 1847, 
in allusion to a transverse furrow crossing the valves from the 
umbones to the middle of the ventral margin. On consulting 
a work received from the late Dr. James Hall, I find he named
