FROM THE COAST OF BRITISH COLUMBIA. 113 
It had been dredged by the writer before, in 1873, at a depth of 200 fathoms in the Gulf 
of St. Lawrence. Other remarkable forms are double examples of Discorbina larisiensis, 
which are far from uncommon in Dr. Dawson’s dredgings; large varieties of Cristellaria 
cultrata, and a Frondicularia which, although common as a fossil in the Chalk of Europe 
and England, was previously unknown as a living species. 
Among the echinodermata, the most interesting species collected is the Astrogonium 
granulare, which is new to the fauna of the Pacific. 
Of the lamellibranchiate bivalves, two, viz., Pecten Alaskensis and Yoldia thracieformis, 
are arctic or subarctic shells which had not previously been taken so far to the south as 
the Vancouver region, while, on the other hand, Limatula subauriculata and Leda acuta are 
species which have not hitherto been recorded as occurring so far to the north, on the 
west coast of North America. 
The number of species of gasteropoda collected is unusually large, and among these, 
Leptochiton cancellatus, Bela violacea, Cancellaria circumcincta, Admete viridula, and Sipho 
Verkruzeni are northern forms new to the Vancouver district; while Solariella peramabilis 
and Barleeia subtenuis are Californian shells now for the first time placed upon record as 
living within it. Astarte undata and Eulima incurva (—distorta auct.) if correctly identified, 
seem to be new to the fauna of the west coast of North America ; Margarita cidaris, of which 
a fine series was obtained, was previously known only from a single specimen; and 
Cadulus aberrans and Leptochiton punctatus are here described for the first time. 
It would appear that the outer and exposed western coast of Vancouver Island is 
tenanted by a somewhat different assemblage of marine invertebrata from that which lives 
in its eastern, south-eastern and more land-locked waters. So far, Tellina Bodegensis, 
Cadulus aberrans, Pachypoma gibberosum, Chlorostoma funebrale and Olivella biplicata have been 
found by the Survey collectors on the west and north coast of the Island only, while 
Acmeæa instabilis, Cryptobranchia concentrica, Haliotis Kamtschatkana and Phorcus pulligo, though 
not exclusively confined to the outer coast, appear to be rare in its eastern and south- 
eastern waters. The exact geographical distribution of the different species around the 
coast of Vancouver Island, however, has yet to be ascertained, and the preceding remarks 
have only been written with the view of directing attention to the subject. 
For critical and valuable suggestions in regard to some of the mollusca collected, and 
for the identification of eight species of gasteropoda, the writer is indebted to Mr. W. H. 
Dall of the United States National Museum at Washington. 
The following is alist of the species that have been identified so far. 
FORAMINIFERA. 
MILIOLINA SEMINULUM, L. Strait of Georgia at station No. 2, Discovery Passage at station 
No. 7, and Queen Charlotte Sound at station No. 17,—one specimen at each. 
Minioniwa FERUSSAON, d’Orbigny. With the preceding at station No. 17, one specimen. 
RHABDAMMINA ABYSSORUM, M. Sars. Strait of Georgia at stations Nos. 4 and 5, Queen 
Charlotte Sound at station No. 17, and Quatsino Sound at station No. 20,—abundant 
at each,
