IX.—On some Marine Invertebrata dredged or otherwise collected by Dr. G. M. Dawson, 
in 1885, in the northern part of the Strait of Georgia, in Discovery Passage, 
Johnstone Strait, and Queen Charlotte and Quatsino Sounds, British Columbia ; 
with a Supplementary List of a few land and fresh water shells, fishes, birds, 
etc., from the same region. By J. F. WHITEAVES. 
(Read May 27, 1886.) 
As stated in his preliminary report,’ Dr. Dawson’s geological explorations of certain 
parts of the coast of British Columbia, in the summer of 1885, in which he was assisted 
by Mr. D. B. Dowling, were prosecuted by means of a schooner. In the intervals of 
the more purely geological work, this mode of locomotion afforded many opportunities, 
which were utilized to their fullest extent, for collecting marine invertebrata, on the 
shore, by the towing net or by the dredge. The title of the present paper sufficiently 
indicates the area examined, at many points within which collections were made at low 
tide. The material collected by the towing net, being to a large extent microscopical in 
its character, has not yet been examined. The dredge was used successfully at depths of 
of from seven to fifty fathoms, at the following localities :— 
STATIONS. STRAIT or GEORGIA. 
No, 1.—Ballinac Channel, opposite Lasqueti Island, in forty fathoms. 
2.—False Bay, Lasqueti Island, in ten to twenty fathoms, sand and gravel. 
3.—Off the mouth of Qualicum River, Vancouver Island, in forty fathoms, sand and gravel. 
4.—Off the north end of Texada Island, in fifty fathoms, sandy mud, 
5.—Between Hernando and Cortez Islands, in eight to twenty fathoms, sand. 
6.—Between Mary and Cortez Islands, in fifteen to twenty fathoms, sand. 
Discovery PASSAGE. 
7.—Dunean Bay, Vancouver Island, in ten to twenty fathoms, sand and gravel. 
8.—EIk Bay, Vancouver Island, in twenty to twenty-five fathoms, sand and gravel. 
JOHNSTONE STRAIT. 
9.—Blinkinsop Bay, on the mainland of British Columbia, in ten fathoms, sand and mud. 
10.—Forward Bay, Cracroft Island, in fifteen to twenty-five fathoms. 
Queen CHARLOTTE SOUND. 
(Including Blackfish and Fife Sounds and Broughton Strait.) 
11.—Farewell Harbour, between Swanson, Lewis and Berry Islands, in nine fathoms, gravel. 
12.—Fresh Water Bay, Swanson Island, Blackfish Sound, in ten fathoms, gravel and coarse sand.
