234 ROYAL ."-OCIKTY OF CANADA 



As the Brachiopotla (though not mollusca) were treated in the former 

 paper, they have been, for convenience, also considered in this, and arc 

 included in the foregoing calculations. If the four species of this group 

 are eliminated, it will leave us a total of true mollusca of four hundred 

 and fifteen species. 



The principal papers, relating specially to British Columljian mol- 

 lusca, that have appeared since the date of the Preliminary Catalogue 

 are: 



(1.) A paper by Dr. C. F. Newcombe, entitled "Some new or rare 

 Species of Marine Mollusca recently found in Britisli Columbia." It was 

 l)ublished in the "Nautilus,' vol. x, pp. l(J-20 (June, 1896), and adds 

 thirteen species to our list and gives interesting notes on several others. 



(2.) An important paper by Dr. Dall, "Notice of some new or inter- 

 esting Species of Shells from British Columbia and the adjacent region.' 

 This was published in "Bulletin No. 2 of the Natural History Society of 

 British Columbia," pp. 1-18, plates i and ii (January, 1897). In it Dr. 

 Dall describes and figures twenty-two new species, nearly all of them from 

 our coasts. 



There is also a list of British Columbia mollusca (prepared by Dr. 

 Newcombe) in the lately-issued " Catalogue of the Collections of Natural 

 History and Ethnology in the Provincial Museum, Victoria, British 

 Columbia." 



Besides the above many papers have been published in the Pro- 

 ceedings of the United States National Museum and of the Academy of 

 Natural Sciences of Philadelphia, and in the " Nautilus," which deal 

 incidentally with British Columbian species. Most of these papers are 

 referred to, and their titles are given, in these notes. 



NOTES. 



1. Terebratulina unouicula, Carpenter. 



Dall says (Proc. U. S. Nat. Mus., xvii, 719) that this form cannot be 

 sejyarated even as a variety from European specimens. Our species must 

 therefore stand as Terebratulina raput-serpentis, Linne. 



3. Laqueus Californicl's, Koch. 



Dr. Dall has determined that the Vancouver shells are not the true 

 L. Californicvs of Koch, but a distinct species, which is really the adult 

 form of that named by him Me</erlia Jefreysi Nos. 3 and 4 of my Pre- 

 liminary Catalogue must therefore be united, and must stand as Laqueus 

 Jeffreysil, Dall. (See Amer. Jour, of Conch., vol. vii, p. 65, ])1. xi, figs. 

 7-10, March, 1371 ; and Proc. U. S. Nat. Mus., vol. xvii, p. 725, 1894.) 



This species has been taken not rarely at low tide on Haddington 

 Island (Harvey) and in deep water oil' Nanaimo.
