bella (Nitidella) Balli} I have compai-ed some of our shells with Smith's 

 type and tind no ditference whatsoever. 



AMPHI8SA, H. and A. Adams. 



233. Amphissa corrugata, Eeeve, sp. 



Buccinnin corrugatuni, Kve., Conch. Icnn.,Mon. of Bucc, no. 110 (February, 1S47). 



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 ordinaiy 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 Hai'bour (Queen Charlotte Islands), should most 

 probably be referred to this form. 



TROPHOX, De Montfort. 



2M. Trophon multicostatus, Eschscholtz, sp. 



Miirex mulficosfafiis, Esch., Zool. Atlas, pt. 2, p. 11, pi. ix., fig. i (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 A"ic- 

 toria, and it was taken by Dr. Dawson in Queen Charlotte Sound and 

 Johnston Straits, but not at the Queen Charlotte Islands. 



235. Trophon Orpheus, Gould, sp. 



Fusus OrjjJuu.s, Gould, Proc. Bost. Soc Nat. Hist., vol. iii., p. 142 (May, 1849); and 

 U. S. Expl. Exped., Mollusca, p. 234, fig. 285-28oB (1852). 



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 possibl}' 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 T. 

 Stuarti.
