GLACIAL BOULDERS OF OUR FISHERIES.—HONEYMAN. 2138 
sponge—Reniera. This was for some time, singular by the incor- 
poration of the diatom, Grammatophora serpentina, in abund- 
ance. From this I gave it the specific name anguillellide. 
Mr. McLeod, of Demerara, gave me a piece of Pecten tenui- 
stricatus from Chester, N.S., with an incrusting sponge,a Reniera. 
My collection in the Canadian Department of I. F. E., Lond, 
1883, contained a short, branching sponge, which was found 
attached to a valve, of Ostrea virgineana from Prince Edward 
Island. This is Swberites edowardit. 
Notre.—Two other boulders have been added to our collec- 
tion. X is of Lower Carboniferous Limestone. Its weight is 
31 lbs. On itare two Suberites, one Myxilla, and two Stellittas 
etoile- pistol et. 
Boulder Y has a Suberites.
