Amer. Jour. Conch., vol. vii., p. 136, pl. xv., fig. 11 (November, 1871). 
A single specimen of this little shell was dredged, in about five 
fathoms, in Clayoquot Sound last September by Dr. Newcombe. It was 
determined for him by Dr. Dall. Tornatina harpa was described from 
Monterey, California, “ Three specimens adhering to the tentacule of 
Actinias.”

This shell is not very common. It has been recorded from the 
Straits of Georgia, Quatsino Sound and the Queen Charlotte Islands, by 
Mr. Whiteaves, under the name C. alba. Dr. Newcombe has dredged it 
at Comox and Clayoquot Sound, Prof. Macoun at Sooke, and I have 
dredged it in Departure Ray. 
I have seen the type of C. propinqua which is in the Naturai History 
Museum, South Kensington. It is a fine specimen of C. attonsa.

= Bulla hyalina, Turton, Mag. Nat. Hist., vol. vii., p. 353 (1834).

GbE  ebC. 
Five immature shells were found by me among roots of kelp washed 
ashore near Clover Point, Victoria, in 1888. Dr. Dail, to whom these 
were submitted, referred them doubtfully to debilis, Gould. 
Lately I have seen a full-grown specimen taken at Sooke by Prof. 
Macoun, and I find it to accord exactly with the description of Utri- 
culus hyalina in Jettreys’s “ British Conchology,”’ and also with the figure 
of Gould’s Bulla debilis in the “ Invertebrata of Massachusetts.” 
D. pellucida is not a very common species in Kuro. ean seas. Jeffreys 
has noted about thirty localities for it on the British coasts, and quotes 
it also from Norway, Sweden, Iceland and Greenland, and from Madeir: 
and the Canary Islands. 
As debilis it is on record from Eastern American coasts and it is now 
recorded I think for the first time from the Pacific Ocean. 

'T adopt the synonymy of this species as given by Verrill in Proc. U.S. Nat. 
Mus., 1880, p. 382:
