1915] PALAEOZOIC FOSSILS FROM HUDSON Bay. 9 
Aulocopella. .. . Von Aulocopium dadurch verschieden, dass der 
Skeletradiant nicht an oder dicht tiber dem Fusspunkte, sondern wie 
z. B. bei den Astylospongiden inmitten des Spongienk6rpers liegt’?! It 
is manifest that this determinative feature cannot be ascertained 
in our fragment, but the striking resemblance to Aulocopella winni- 
pegensis would suggest the sub-genus. This remarkable sponge was 
described by Dr. Rauff (op. cit.) from a specimen from Cat Head, Lake 
Winnipeg, submitted to him by Dr. Whiteaves, who refigures the 
species in the Third Volume of Palaeozoic Fossils (Page 145, Plate 16, 
Figures 1-3 and Figure 9, p. 146). On account of the great similarity 
of our specimen I am inclined to regard the section as passing vertically 
through one of the lobes of an Aulocopella resembling A. winnipegensts. 
The two species can scarcely be identical, for our form is very much 
larger and shows distinct radial pores which have not been observed 
in A. winnipegensis. 
Locality—Lower rapids, Shamattawa river, Manitoba. 
Horizon—Ordovician.
