It seems probable that tbis is identical with B. twmidulum, but I 
had considered it a variety of B. hydrophanum. F¥riele and Jeffreys 
refer B. tumidulum to B. hydrophanum Uan., as a variety. The 
latter is described as smooth, with a smooth epidermis, and is a more 
elongated form, with less convex whorls. . Mérchi, Friele (Nyt. 
Mag. Naturv., xxiii, [p. 4], pl., figs. 7, 7a, teeth and operculum, 
1877), seems to be a closely related form, and also has a roundish 
operculum with a central nucleus. Jeffreys unites this, also, to B. 
hydrophanum. Uf B. tumidulum Sars be really a variety of B. 
hydrophanum Uan., then the latter must, apparently, be added to 
the list of species inhabiting the Grand Bank.

This name is proposed, provisionally, for the shell figured by Gould 
(ed. I) and described as B. Humphreysianum* by Dr, Stimpson, It 
differs from the European species, of that name, as already mentioned 
by Jeffreys and others, in having a ciliated epidermis and in other 
characters. ; 
This shell is remarkable for its swollen, rounded whorls, the deep 
excavation of the columella-lip, the anterior expansion of the rounded 
outer lip, and the thinness and nearly smooth surface of the shell. 
This shell may, perhaps, prove to be only a variety of some pre- 
viously known species. In that case, Gouldii may still be used as a 
variety name, to designate the form. It does not appear to corre- 
spond with any of the forms described by European writers. 

* IT add references to this European shell, which, probably, has not been met with 
on the American coast.
