on my authority, but I am afraid this is a mistake, for which I must 
apologize, as a re-examination shows that all my specimens are X° bipin- 
nata, 
SCAPHOPODA. 
DENTALIUM, Linne. 
127. DENTALIUM INDIANORUM, Carpenter. 
Rept. Brit. Assoc., 1865, p. 648 (August, 1864) = pretiosum, Nuttall. 
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. Jeffreys supposed 
this species to be equivalent to the British D. entale, Linne. 
128. DenraLtum RECTIUS, Carpenter. 
Rept. Brit. Assoc., 1863, p. 648 (August, 1864); and Proc. Acad. Nat. Sci. Phila., 
1865, p. 59. 
This species was first found (dead) in Puget Sound by Kennerley, 
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. Richardson, 
near Victoria in 1875. 
CADULUS, Philippi. 
129. CADULUS ABERRANS, Whiteaves. 
Trans. Roy. Soc. Canada, 1886, vol. iv., sect. iv., p. 124, fig. 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 fathoms mud. 
The shell has not so far as I know been found anywhere else in 
British Columbia, but Mr. Whiteaves has a note that it has been dredged 
near the Catalina Islands by Dr. J. G. Cooper. 
GASTEROPODA. 
PTEROPODA. 
It would perhaps have been better to have omitted all mention of 
this order as no species have been collected by recent observers, but I 
did not like to omit any name that has had a place on Carpenter's list
