IL.—Sponges from the Coasts of Northeastern Canada and Greenland. 
By Lawrence M. LAMBE, F.G.S., oF THE GEOLOGICAL SURVEY. 
(Read May 29, 1900.) 
In a paper entitled “ Sponges from the Atlantic Coast of Canada,” 
published in 1896, in the Transactions of this Society, the writer gave 
the results of a careful study of a number of recent marine sponges from 
the River and Gulf of St. Lawrence, the Atlantic Coast of Nova Scotia, 
and the Bay of Fundy. 
The present paper consists of identifications or descriptions. of 
species found farther to the north, off the coast of Labrador, in Davis 
Strait and Baffin Bay, and may be considered, in a measure, as supple- 
mentary to the first paper. The specimens are from the museum of 
University College, Dundee, Scotland, and have been received from 
Professor D’Arcy W. Thompson, at whose request the examination of 
the collection in question was undertaken. The majority of the speci- 
mens are from Davis Strait, and were for the most part collected by 
Mr. A. M. Rodger, Professor Thompson’s assistant, who accompanied 
Captain Phillips, of the SS. “ Esquimaux,” on a whaling voyage in 
1892, and also visited East Greenland in 1894 with Captain Robertson, 
of the S.S. “ Active.” References are also made to a few species from 
Hudson Bay and strait obtained, of late years, by Doctor Robert Bell 
and Mr. A. P. Low, of the Geological Survey. 
All the specimens in the collection are preserved in alcohol.
