The list of invertebrates is compiled from materials accumu- 
lated during the summer of 1864, while the author was coasting 
from the little Mecatina Island in the Gulf of St. Lawrence to 
Hopedale, the lowest Moravian settlemeiit. Though the list is 
naturally imperfect, still it gives some important information as 
to the depth at which the dillcrcnt species were found, the nature 
of the sea-bottom, &c, : some new species are described. Dr. A. A. 
Gould, Dr. W. Stimpson, and Mr. E. S. Morse gave valuable 
assistance in identifying the species. Many typographical errors 
which will be met with in an article by Mr. Packard on the 
marine invertebrates found at Caribou Island, published in the 
' Canadian Naturalist^ for 1863, will be found corrected in this 
memoir.

In this monograph of the Polyzoa of the Northern and Arctic 
seas, Smitt describes at length, giving a detailed synonymy, 
104 species. Many of these species contain, however, as well- 
marked varieties, the species of other writers on the Polyzoa. 
In the ntimbers of the ' Proceedings of the Stockholm Academy^ 
quoted above, the descriptions of the first 62 species will be found, 
embracing the Polyzoa belonging to the Cyclostomata, Cteno- 
stomata, and the first six families of the Cheilo stomata. In com- 
piling tins monograph the author has had access to the valuable 
collections of Loven, Lilljcborg, O. Torcll, Malmgren, Uggla, 
M oiler, Steenstrup, and others.
