Fusus. The British species are arranged by J effreys in the following manner : 
— 1. antiqtms (L.), with four varieties , (a/6a, ventricosa, striata, gracilis) and 
twelve monstrosities; 2. norvcgicus (Chemn.); 3. turtoni (Bean); 4. islandi- 
cus (Chemn.), the young of which ( Hancock) ; 6. gracilis (Da Costa) 
=islandicus of Forbes & Hanl. ; 6. propinquus (Alder), including as variety 
Tritonium turritum (Sars) ; 7. huccinatus (Lam.), distinct from vulpinus 
(Born) ; 8. herniciensis (King) = Trit. islandicum of Loven ; 9. fenestratus 
(Tmi.)= Buccinum fusiforme (Brod., Forb. & Hanl.).

[ Urosalpinx, Stimps.] Buccinum plicosum (Gould) [Menke=Fit<^ws cinereus, 
Say], feeding on oysters, piercing the shell by the tongue near its apex, 
called drill by the American oyster-breeders. Fellowes, Americ. Naturalist, 
i. pp. 200-201. 
Bachesis minima (Montagu, ^ Buccinmn) —hrunnea (Donov.)=mammt7/a<« 
(Risso) belongs to the Muricidm, not Fleur otomidee. Jeffreys, Brit. Conch, 
iv. p. 313, pi. 6. fig. 1. The same synonymy is given by Gonzalez Hidalgo, 
Journ. Conch, xv. p. 283 ; but he includes also Murex felinece (Chiaje). 
Buccinidas. 
This family, as limited by Stimpson, corresponds nearly to the 
Fusacea of Troschel, containing members of Muricidee and 
Buccinidee of former authors. It is characterized by the lateral 
plates of the radula having 2-4 strong teeth ; the central plate 
is commonly not broader than long, or, if so, its posterior edge 
is straight, and has 3-7 teeth, never more, as in the Nassida, 
Dr. Troschel subdivides this family into 6 subfamilies : — 
a. Buccinina. Median plate broader than long, sinuated in front, behind 
straight with 3 or 4 teeth. Genera : Cominella, Buccinum, and Volutharpa, 
The radula of the following is described and figured : — C. limhosa (Lam.), 
B, undatum (L.), hydrophanum (Hancock), gronlandicum (Chemn.), glaciate 
(L.), V.perryi (Jay), Troschel, I, c. pp. 69-72, pi. 6. figs. 6-14 ; Cominella ma- 
culata (Martyn) is excluded.
