ADDITIONAL NOTES. 
LICHENALEA HALL. 
— 
Some years before he died, the late Dr. James Hall furnished 
the writer with the figures of ‘‘Lichenalea Concentrica’’ and the 
fragment of a parasite attached to Strophostylus he had named 
‘Var. L. Parvula.’’ The former is not at all uncommon in the 
Niagara chert here; the latter represents, perhaps, a distintt 
species which is frequently discovered fixed on one of the plain 
globular Niagara sponges. I cannot remember finding it at- 
tached to either ‘‘ Aulocopinas’’ or the more numerous “‘ Rusosig- 
num.’’ In searching for flint-flake fossils in glaciated drift-chert 
and also in a layer in the Hamilton quarries, I occasionally found 
what I considered a distinct and well marked species of the 
Bryozoon. I therefore concluded during the past collecting sea- 
son to carefully examine the eight feet of upper Niagara chert 
which remains unremoved by glacial action. A little beyond the 
railway rock cutting, the writer had not been very long at work 
when he discovered three or more members of the family which, 
he thinks, may be new species. They are not confined to a singie 
bed, and the section of a sponge was obtained in one of the layers; 
the weathered chert in which they were embedded was very 
brittle near the edges and some were destroyed in extracting, but 
three in good preservation were secured. In describing the type 
of the Genera Lichenalea Concentrica, it appears to me Dr. James 
Hall himself entertained doubts of his own correctness in assign- 
ing one or more fragments in his possession to the Bryozoon in 
question. I would eall your attention to his own remarks on the 
subject: ‘‘The variations in expression, in the many forms of this 
species (Lichenalea Concentrica), size, proportion and arrange- 
ment of the cellules upon the surface, and the aspect produced 
by weathering or maceration, are so great as often to induce a 
reference to distinct species.’’
