xiiriety oi' fidicuhi" which makes mo doubt whether he had genuine 

 tabulata before him. 



Lastly there is B. violacea of which a single living specimen was 

 taken, according to Whiteaves. in Alert Baj' 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, Kisso. 

 We have four species : 



203. Mangilia scuLPTiTRATA. Dall, sp. 



Bria srulpfiirafa, D.ill, Proc, V. S. Nat. Mus.. vol. ix. (1886); p. 2iHt. pi. iv. fi^r. 7. 



204. Mangilia angulata. (Carpenter. 



Kept. Brit. Assoc, 18(5.S, p. f5.=)8 (Augt., 1864); and Ann. Mag. Nat. Hist., .series H. vcd. 



XV., p. 394 (May, 1865). 



205. Mangilia interfossa. Carpenter, 



R('lit. Brit. Assoc. 1863. p. 6.58 (Augt., 1864) ; and Ann. Mas. Nat. Hist., series 3, vol. 



XV., p. 29 (Jan. 1865). 



200. Mangilia levidensis, Carpenter. 



Rept. Brit. A.ssoc, 1863, p. 6.58 (Augt., 18(>4); and Proc A ad. Nat. Sci. Phila.. 1865, p. 63. 

 = funcbralc, Dall, Amer. Journ. Con h., vol. vii., p. 1(X) (1871), teste Dall, Proc 

 U. S. Nat. Mus., vol. ix. (1886), p. 299. 



The tirst 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. 

 Daw.son. 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 con.sidei-ably 

 larger than the three last mentioned. It has only been found, recently, 

 by Dr. Xewcombe and myself, at Comox and Victoria. The type 

 s])ecimens of levidensis and angulata were from Puget Sound and of inter- 

 fossa tVoni Xeeah Bav. 



Dr. Xewcombe has a shell apparently of the present genus which 

 /Dr. Dall has informed him is probably of an undescribed species. Still 

 another shell which niav belong here was described by Mr. K. A. Smith 

 as Pleurotoma Vancouver ensis (Ann. Mag. Nat. Hist., series 5, vol. vi.. ]). 

 280 (1880), but [ have not seen the description and do not know tlio 

 species.
