HYDROID8 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.
