In addition to these, there are in the museum of the Cana- 
dian survey a few fragmentary crinoids, several species of 
Polyzoa, a few Brochiopoda, pelecypoda and Gasteropoda, and 
one pteropod, (an undetermined species of Tentaculites) from 
the Corniferous of Ontario, that liave yet to be studied. 
From this h?t it would appear that corals form by far the 
most conspicuous feature in the fauna of the Ontario Corni- 
ferous. But, although in places this formation is mainly a 
large coral reef, it is obvious that quite a number of the species 
that have been proposed therefrom are based upon very insuf- 
ficient characters. For some time past the writer's friend and 
colleague, Mr. L. M. Lambe, has been engaged in a much- 
needed revision of the Canadian palaeozoic corals, and when 
tills revision is completed, as it is hoped it soon will be, it will 
doubtless materially reduce the number of species from the 
Corniferous of the province. On the other hand, the num- 
bo'- of species of polyzoa, brachiopoda and mollusca from that 
formation, in collections that have yet to be studied, will be 
quite largely increased. 
The fossils of the Hamilton formation of Ontario have been 
reported on by Billings, Nicholson, Hall, and more recently 
by the writer, who has published two small monographs upon 
them.. In the latter of these, published in November, 1898, 
219 species are recognized and recorded as follows: 
Sponges 2 
Corals (inclusive of Stromatoporoids) 40 
Echinodermata 16 
Vermes 14 
Polyzoa (=Bryozoa) 40 
Brachiopoda 61 
Pelecypoda (=Lamellibranchiata) 13 
Gasteropoda 12 
Pteropoda 3 
Cephalopoda 8 
Ostracoda 3 
Phyllopoda i 
Trilobita 4 
Fishes 2

Several additional species of Fenestellidae and Monticulipo- 
ridre are indicated, in the Canadian survey and other collec-
