FROM THE COAST OF BRITISH COLUMBIA. 127 
ACMÆA MITRA, Eschscholtz. Low tide at Malaspina Inlet in the Strait of Georgia, and 
Queen Charlotte and Quatsino Sounds. Dredged also in Queen Charlotte Sound at 
stations Nos. 12, 15 and 18, and at the entrance to Quatsino Inlet at station No. 19. 
Moderately abundant near low water mark almost everywhere. 
ACMA INSTABILIS, Gould. Low tide on the north and north-west coast of Vancouver 
Island, between Nahwitti Bar and Quatsino Sound ; three adult, but dead shells. 
CRYPTOBRANCHIA CONCENTRICA, Middendorf.  (—Lepeta cæcoides, Carpenter.) Queen 
Charlotte Sound at station No. 17, one living specimen; and Quatsino Sound at 
station No. 20, several. 
GLYPHIS ASPERA, Eschscholtz. Common, living at low tide in Malaspina Inlet, Strait of 
Georgia ; in Johnstone and Broughton Straits ; in the Goletas Channel, and on the 
west coast of Vancouver Island, north of Quatsino Sound. 
PUNCTURELLA CUCULLATA, Gould. Low water at Race Passage, Johnstone Strait, one 
large, living specimen. Dredged also alive, but sparingly, in Discovery Passage 
at station No. 7, in Queen Charlotte Sound at stations Nos. 12 and 17, and in 
Quatsino Sound at station No. 20. 
PUNCTURELLA GALEATA, Gould. Dredged living, but in very small numbers, in Discovery 
Passage at station No. 7, in Johnstone Strait at station No. 10, in Queen Charlotte 
Sound at stations Nos. 12,15 and 18, and in Quatsino Sound at station No. 20. 
Specimens sometimes occur which seem to be intermediate in their sculpture 
between this and the preceding species. 
Haniotis KAMTSCHATKANA, Jonas. Living at a little below low tide at Port Neville, on 
the mainland of British Columbia, north of Johnstone Strait; at Beaver Harbour, 
on the north-east coast of Vancouver Island; in the Goletas Channel; and at the 
entrance to Quatsino Inlet. Dr. Dawson says that this species is most abundant in 
exposed situations on the northern and outer coast of Vancouver Island, but that 
it is rarely met with in the Strait of Georgia or other land-sheltered waters. 
The animal, or foot of the animal, is eaten by the Indians, and dried for sale 
to the Chinese, while the nacreous interior of its shell is largely used by the 
Indians for inlaying and other ornamental or decorative purposes. 
PACHYPOMA GIBBEROSUM, Chemnitz. On rocks and kelp at a little below low-water mark 
in Quatsino Sound; abundant at some localities. 
The thick, calcareous operculum of this shell is used for ornamental inlaying, 
in wooden ware, by the Indians of the coast. 
LEPTOTHYRA SANGUINEA, Z. (Sp) Living, at low tide, in Johnstone and Broughton 
Straits, in the Goletas Channel, and on the east side of Queen Charlotte Sound. 
Dredged, also, in Queen Charlotte Sound at station No 15, and in Quatsino Sound 
at station No. 20. 
Mr. Tryon appears to be mistaken in supposing that the Californian shells 
which Dr. Carpenter referred to this species, have a “corneous” operculum and
