variety of fidicula” which makes me doubt whether he had genuine 
fabulata before him.

Lastly there is B. violacea of which a single living specimen was 
taken, according to Whiteaves, in Alert Bay by Dr. Dawson, 
The two last named species approach in form the next genus and 
would not be likely to be confused with typical Belas. 
MANGILIA, Risso. 
We have four species : 
203. MANGILIA scULPTURATA, Dall, sp. 
_ Bela sculpturata, Dall, Proc. U. S. Nat. Mus., vol. ix. (1886); p. 299, pl. iv, fig. 
1 
204. MANGILIA ANGULATA, Carpenter. 
Rept. Brit. Assoc., 1863, p. 658 (Augt., 1864); and Ann. Mag. Nat. Hist., series 3, vol. 
Xv., p. 394 (May, 1865). 
205. MANGILIA INTERFOSSA, Carpenter. 
Rept. Brit. Assoc., 1863, p. 658 (Augt., 1864); and Ann. Mag. Nat. Hist., series 3, vol. 
xv., p. 29 (Jan. 1865). | 
206. MANGILIA LEVIDENSIS, Carpenter. 
Rept. Brit. Assoc., 1863, p. 658 (Augt., 1864); and Proc. Acad. Nat. Sci. Phila., 1865, p. 63. 
= funebrale, Dall, Amer. Journ. Con h., vol. vii., p. 100 (1871), teste Dall, Proc. 
U.S. Nat. Mus., vol. ix. (1886), p. 299. 
The first three of these species are closely related. M. interfossa and 
angulata have not been detected here since Carpenter’s time but sculptur- 
ata is common in nearly all the Vancouver Island localities I have 
examined. It was taken also at the Queen Charlotte Islands by Dr, 
Dawson, M. sculpturata is a rather variable shell and Dr. Dall tells me 
that northern specimens lack the colour band that is so conspicuous in 
our shells. 
M. levidensis is a beautiful shell quite distinct from and considerably 
larger than tbe three last mentioned. It has only been found, recently, 
by Dr. Newcombe and myself. at Comox and Victoria. The type 
specimens of levidensis and angulata were from Puget Sound and of inter- 
fossa from Neeah Bay. 

Dr. Newcombe has a shell apparently of the present genus which 
Dr. Dall has informed him is probably of an undescribed species. Still 
another shell which may belong here was described by Mr. E. A. Smith 
as Pleurotoma Vancouverensis (Ann. Mag. Nat. Hist., series 5, vol. vi., p. 
286 (1880), but I have not seen the description and do not know the 
species.
