Postsoript.—Since our remarks on fossil sponges, in the “ Minerals and Geology 
of Canada,” page 505, were printed off, we have received a publication of the 
Geological Survey, containing descriptions of various new species of Lower Sllu- 
rian Fossils, by E. Billings, F.G.S. In this publication, Mr. Billings describes, 
under the generic name of ZHospongia, two sponges recently brought by Mr. 
Richardson from the Chazy Limestone of the Mingan Islands, together with a 
third species (Astylospongia parvula) from the Trenton Limestone of Ottawa 
City. These, however, as compared with the generality of Silurian fossils, may 
be looked upon as quite of exceptional occurrence. Nevertheless, to prevent 
misconception, the reader is requested to alter the words “ determinate forms,” 
page 505, line 16, into “characteristic forms.”—KE,. J. C. 
TORONTO: PRINTED BY LOVELL AND GIBSON.
