A. E. Yerrill — Catalogue of Marine Molluseci. 
In order to make this list more complete, I include here the fol- 
lowing species of Buccinum, although they may not have been taken 
south of Newfoundland and the Gulf of St. Lawrence. 
Buccinum Tottenii Stimpson. 
Buccinum ciliatum (pars) Gould, Invert. Mass., p. 307, 184] ; ed. II, p. 368, (non 
Fabr.) 
Dawson, Canadian Nat., ii, p. 415, pi. 7, fig. 5, 1857, (non Fabr.) 
Buccinum Tottenii Stimpson, Review Northern Buccinums, Canadian Nat., ii, p. [23], 
Oct., 1865. 
Buccinum %ot1enii Jeffreys, Northern Species of Buccinum, Ann. and Mag. Nat. 
Hist., vi, p. 425, Dec.. 1880. 
Friele, Catal. Norweg. Nordm. Exp. Spitzb. Moll, p. 278, pi. 7, figs. 11, 12 (denti- 
tion). 
f Tritonium terrce-novce Morch, Catal. Moll, du Spitzberg, p. 14, (extract from Ann. 
Soc. Malacol. Belg., iv, 1869). 
Buccinum terrcc-nova Leche. Kongl. Sv. Yet.-Akad. Handl., xvi, [p. 61], pi. 2, figs. 
30a, b (shell), 30c, d (dentition), 1878. 
Grand Bank, Newfoundland, — coll. Totten (t. Stimpson). Several 
specimens from the Grand Bank have been presented to the TJ. S. 
Fish Com. by the fishermen of Gloucester, Mass. Off Metis, R. St. 
Lawrence! (coll. Dawson.) Spitzbergen, 20 to 50 fathoms, — Leche, 
Friele. 
By Jeffreys, B. Terrce-Novce (Morch) is regarded, after an exami- 
nation of the original specimens, as identical with B. Tottenii. To 
judge from some of the descriptions and figures, it would appear to 
be a variety of B. cyaneum , as Morch himself suggested. The figure 
given by Leche appears, however, to represent a carinated variety of 
B. Tottenii. 
Buccinum tumidulum G. O. Sars. 
Op. cit., p. 263, pi. 25, figs. 5, 6, pi. x, fig. 13. 
This species is remarkable for the nearly smooth, ventricose whorls, 
for the wide extension of the enamel over the body-whorl (as in B. 
hyclrophanmn ), and especially for the nearly round operculum, which 
has a central nucleus. 
From the Grand Bank, I have a thin, white shell, which agrees ex- 
actly with Sars’ figure in size and form, but it lacks the operculum. 
It has the same extension of the enamel, and is finely and closely 
spirally striated; close to the suture there are slight and short undu- 
lations. The columella-lip is excavated and curved as in Sars’ 
figure.
