on my authority, but I :ini afraid this is a mistake, for which I must 

 apologize, as a rc-examination shows that all my specinu-ns arc X. bipin- 

 ixata. 



SCAPHOI'ODA. 



DENTALIUM, Linne. 

 127. Dkntalium indianorum. Carpenter. 



Rei)t. Brit. Assoc, IStiM, ]>. (US (Au.nnst. 1S(>4) =; /n-i'fio.sii m, Xiittall. 



Common in our northern waters though not yet met with on the 

 eastern or southern coasts of Vancouver Island. 



Shells of this species were formerly of considerable value as a 

 medium of exchange among the Indians and they are still extensively 

 used by the aborigines for ornamental purposes. Jetlreys supposed 

 this species to be equivalent to the British D. enfale. Linne. 



128. Dentalium reotius, Cai'penter. 



Kept. Brit. Assoc, ]S(«, p. (?4S (Aujiust, 18(>t) ; and Proc Acad. Nat. Sci. Phila., 



180.=;, p. .5!). 



This species was tirst found (dead) in Puget Sound by Kennerlej^, 

 and Carpenter speaks of it as being " very rare." The only British 

 Columbian specimen I have seen or heard of, is the one in the Geolo- 

 gical Museum at Ottawa, which was dredged alive by Mr. Eichardson, 

 near Mctoria in 1875. 



CADULUS, Philippi. 



129. Cadulus aberrans, Whiteaves. 

 Trans. Roy. Soc Canada, 188«i, vol. iv., sect, iv., p. 124, tig. 2. 



This species was one of Dr. Dawson's discoveries. It was dredged 

 by him in 1885, very abundantly in Forward Inlet, Quatsino Sound, in 

 10-20 f-ithoms mud. 



The shell has not so far as I know been found an^'whei'e else in 

 British Columbia, but Mr. Whiteaves has a note that it has been dredged 

 near the Catalina Islands by Dr. J. G. Cooper. 



GASTKROPODA. 



PTBEOPODA. 



It would perhaps have been better to have omitted all mention of 

 this order as no species have been collected b}' recent observers, but I 

 did not like to omit any name that has had a place on Carpenter's list
