subsequently found to belong to the Articulata, and not to the fishes 
(Pisces) at all. Indeed it is generally supposed the latter appeared ~ 
for the first time in an upper Silurian Sea. A few, however, may 
possibly have put in an appearance at an earlier date. I cannot 
remember having ever seen figured a carved tail-spine to a Crus- 
tacean, and one can scarcely realize such an appendage. 
THE MUSEUM CASES. 
In looking over the two cases at the upper end of the room con- 
tain our local specimens, you may notice a few additions have re- 
cently been made. Hitherto we had no specimens of the rare Conu- 
laria of the Niagaras, figured and described by Dr. Spencer under the 
head C. Niagarifica. ‘The one we now possess is incomplete and 
probably did not attain its usual size (about nine inches in length.) 
Another Conularia, also figured by Spencer as a Hamilton Pteropod 
(Niagara), I did not succeed in getting. It appears to be very rare - 
indeed. I have seen only the one Mr. Turnbull found and one I 
found many years ago. A third specimen, undescribed, and a single 
one alone seen, resembles a modern Theca in appearance. It is 
narrow, sharply pointed at the end, nearly six inches long, and does 
not present any well-marked ornamental striz. 
The more characteristic Pteropod of the Niagara beds, Conularia 
Niagarensis, has two representatives in the case. When better pre- 
servid ones turn up we can transter them to the less conspicuous 
side cases for exchange. 
The insufficiency of space for the display of local organic 
remains has been considerably lessened by the Council of the 
Association furnishing the Section with the trays we applied for. If 
I recollect aright, it was proposed originally to have a single com- 
plete Brachiopod, or Lamellibranch, duly named and labelled in 
each small paper box. But internal casts of each valve, showing 
teeth and muscular impressions, as well as outward marking of shells, 
are also required by students, independent of varieties in each 
family, which often widely differ from the original stock. 
I would suggest, subject to your approval, to substitute smaller 
paper boxes for some of the larger ones, and to transfer the acces- 
saries, viz, single valves, to the trays, which appear more suitable 
. for careful examination. We have a considerable number of fossils
