Grand Manan, "dredged in deep water, encrusting shells, &c." (Stimpson). 

 Gulf of St. Lawrence, at Gaspe Bay and elsewhere, dredged by Sir J. W.

 kinds of Polyzoa, Escharoides Sarsii, &c." (Hincks). A. W. Waters regards 

 this species as a Membranipora and places it in the family Membraniporidee.*

" This very interesting form occurs abundantly. It has only been noticed 

 previously amongst Dr. G. M. Dawson's dredgings from the Queen Charlotte 

 Islands. It is probably an Arctic form. The St. Lawrence specimens hither- 

 to met with are all crustaceous in habit, overspreading the stems of Hydroida. 

 The erect branching form obtained at the Queen Charlotte Islands has not 

 occurred " (Hincks).
