commoner, in similar portions of the family groups here. It may 
occur at Tennessee, but I failed to recognize it in the collection I 
possess from that locality, and probably some may think the speci- 
men merely a variety, and not a distinct species. 
WINONA. 
A very large amount of shingle was exposed along the lake 
shore, and A. Wilson, Esq., informed me they had a considerable 
amount of rough weather after his arrival at the park. The quality 
of material cast up, or laid bare, induced me to imagine that a larger 
amount of specimens than usual might be safely calculated upon, but 
in this I feel rather disappointed. Perhaps this was due in some 
measure to being unable to work as steadily as in former years, 
through an attack of grip or influenza, which weakened me pre- 
viously, and the very hot weather, which rendered it difficult to 
handle the shingle. When it became somewhat cooler another visit 
was paid to the camp, and proved slightly more successful, yet 
hardly came up to the expectations entertained, although I was 
enabled to forward a few rare Cambro-Silurian fossils to the 
Dominion Geological_Survey Office, Ottawa, from the lake shore 
drift. 
Among the specimens sent was a fair example of Dr. James 
Hall’s Orthodesma Curvata, which was found in the Hudson River 
series in Ohio. Another and different species of the family was also 
sent there, but the latter was unfortunately poorly preserved. 
_ Several very fine slabs, containing numbers of the minute Leperditia 
Canadensis (T. R. Jones), were also obtained. 
The Professor published a paper in the Annals and Magazine of 
Natural History, in May, 1898, on “ The Fossil Cypridinidz,” a copy 
of which I received and to which I respectfully call the attention of 
our Geological Section. The figures displayed bear such a close 
resemblance to Leferditia Canadensis, that few of us could recog- 
nize the distinction. If the writer ever noticed this crustacean, pos- 
sibly it may have been when collecting specimens from the Mountain 
Limestones of Tipperary, Ireland. Yet he believes that since then 
he has noticed it also at Burlington Heights (the ancient Lake Beach), 
and looked upon it erroneously as an enlarged form of Leferditza. 
Although the writer made an extensive collection in Western
