bella (Nitidella) Dalli I have compared some of our shells with Smith’s 
type and find no ditference whatsoever. 
AMPHISSA, H. and A. Adams. 
233. AMPHISSA CORRUGATA, Reeve, sp. 
Buccinum corrugatum, Rve., Conch. Icon., Mon. of Bucc., no. 110 (February, 1847). 
Common both between tides and in deeper water. 
The littoral specimens are usually much overgrown with Polyzoa. 
There is a variety that is smaller than the ordinary form, and which in 
some respects approaches A. versicolor, Dall, and A. undata, Cpr. It is, 
however, I believe, only a variety of A. corrugata The specimens 
recorded by Mr. Whiteaves as A. versicolor, from Houston-Stewart Chan- 
nel and Cumshewa Harbour (Queen Charlotte Islands), should most 
probably be referred to this form. 
TROPHON, De Montfort.

234. TROPHON MULTICOSTATUS, Eschscholtz, sp. 
Murex multicostatus, Esch., Zool. Atlas, pt. 2, p. 11, pl. ix., fig. 4 (1829). 
I have retained for this species its familiar west coast name, though 
there is little doubt but that our shell is a form of the European Trophon 
clathratus, Linne, sp. (Syst. Nat., ed. xii., vol. i., pt. 1, p. 1223, no. 563, 
1767). The species occurs here in two forms, the ordinary one with 
the interior of the shell white, and a rarer one with the mouth dark 
chocolate colour. I have seen a specimen of this form in the Natural 
History Museum, South Kensington, labelled as a distinct species, but 
Dr. Dall, who has seen one of my specimens, regards it as merely a 
variety of T. multicostatus. This species occurs not uncommonly at Vic- 
toria, and it was taken by Dr. Dawson in Queen Charlotte Sound and 
Johnston Straits, but not at the Queen Charlotte Islands. 
235. TRopHON OrRPHEUS, Gould, sp. 
Fusus Orpheus, Gould, Proc. Bost. Soc. Nat. Hist., vol. iii., p. 142 (May, 1849); and 
U.S. Expl. Exped., Mollusca, p. 234, fig. 285-2858 (1552). 
This species, according to Dr. Newcombe, is the most abundant 
Trophon at Victoria. It has also been taken by Dr. Newcombe at De- 
parture Bay, and possibly by Dr. Dawson in Cumshewa Harbour. Mr. 
Whiteaves gives it from three localities in Queen Charlotte Sound, but 
he has evidently confused this species with the next, and I believe all 
the specimens in Dr. Dawson’s collections should be included under 7. 
Stuarti.
