HYDROIDS FROM NOVA SCOTIA 
173 
On a bryozoan ( Menipea ternata ) dredged in 25 fathoms in 
Chedabucto bay, Canso. 
This species has been placed in the genus Hebella by some 
authors, but it has no hydrothecal diaphragm and hence cannot 
be placed there. Since Broch found and described the coppinia 
mass there is still better evidence that the species should be 
placed with Lafoea rather than with Hebella as the gonangia of 
Hebella are not massed.
