Wings above dark chocolate-brown ; anterior wings crossed 
near end of cell by a broad transverse yellow fascia, almost

XXIV.—Polyzoa of the Queen Charlotte Islands: Prelimi- 
nary Notice of new Species. By the Rev. THomas HIncks, 
B.A., F.R.S. 
In this paper I propose to give a diagnosis of a number of 
Polyzoa from the Queen Charlotte Islands, entrusted to me by 
Dr. G. M. Dawson on behalf of the Geological Survey of 
Canada. 
These forms will be more fully described and figured in 
a special report on the Polyzoa of these islands, which I hope 
to publish hereafter. As the preparation of the plates may 
occupy some time, it seems better to record the new species at 
once, and so avoid the risk of being anticipated after much 
labour has been expended on the work. 
All critical notes on the species will be reserved for the 
Report. 
Family Membraniporide. 
MeEmBRANIPORA, De Blainville. 
Membranipora nigrans, n. sp. 
Zowcia ovate (variable, sometimes arched above and nar- 
rowing downwards, sometimes broad-ovate, sometimes oval), 
irregularly disposed, margins much elevated, crenate, the 
whole front of the cell covered by a rather coarse stout mem- 
brane of a black colour; oral valve large ; on each side at the 
top a pointed avicularium, placed on the margin, depressed at 
the base, the beak sloping upwards, mandible directed ob- 
liquely downwards; very large avicularta, slightly raised in
