The animals described in this paper were obtained while I 
was working at the Marine Biological Station, Departure Bay, 
Vancouver Island, in the summer of 1911 during my tenure 
of the Reid Fellowship. They include two species — one 
belonging to the genus Phorouis (Wright, 1856), the other 
to the genus Phoroiiopsis (Gilchrist, 1907).

This is a colonial form occurring in large compact, more 
or less hemispherical masses attached to the cretaceous 
sandstone forming the islands situated in Departure Bay. 
'I’he colonies (Fig. 1) measure 5 cm. or more in diameter, and 
generally adhere to overhanging rocks near low-water mark. 
Each colony is composed of numerous individuals with 
brownish chitiuous tubes, so very much intertwined that it is 
difficult to obtain a complete specimen from the tangled 
mass. The proximal ends of the tubes are rounded off, and 
the whole tube seems scarcely as long as the expanded 
animal. The total length of an average large specimen is 
40 mm., the tentacles forming 2 to 6 mm. of this ; the width
