[TAYLOR] MARINE MOLLUSCA 19 
Many of these species were only known, in Carpenter’s time, from 
Puget Sound (that is to say United States) localities, but as nearly all of 
them have already been found to occur in British Columbian waters 
also, we take it for granted that the others will all eventually be found 
within our limits. 
In the present paper 284 marine species are noted as follows :

If we add our 67 land and fresh water species we have a total of 
351 as being the number of British Columbian mollusca at present 
known. 
Of the 81 additions to the list since 1864, more than one-half will 
be found recorded in the four papers, by Mr. J. F, Whiteaves, which 
must now be considered. 
The first of these is an account of a collection made by Mr. J. 
Richardson of the Geological Survey of Canada on the east coast of 
Vancouver Island in 1874-75. It is entitled “ On some Marine Inver- 
tebrata from the west coast of North America” and it was published in 
the ‘Canadian Naturalist,’ vol. viii, N.S. No. 8, December, 1878. 
Eleven species are herein added to our list, one of them “ Cardium 
Richardsoni”’ being described as new to science, This shell has, however. 
turned out to be equivalent to Carpenter’s C. centifilosum. The other 
additions are : 
Megerlia Jeffreysi, Modiolaria nigra, Serripes Laperousii, Kennerlia 
grandis, Pholadidea ovoidea, Surcula perversa, Buccinum polare, Trophon 
tenuisculptus, Trophon muriciformis (== Dallii) and ‘ Margarita Vahlii.” 
This last shell, which I have seen in the Geological Museum, Ottawa, 
is a specimen of the Solariella varicosa of Mighels and Adams, but though 
wrongly identified by Mr. Whiteaves, is none the less an addition to our 
list. 
Mr. Whiteaves's second paper is a more elaborate one. It is “ On 
some Marine Invertebrata from the Queen Charlotte Islands ” and forms 
an appendix (C) to the report of Dr. G. M. Dawson on his explorations
