524 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.xxiv. 
The following groups have been separated as a subfamily by Fischer 
on account of the edentulous rhachidian plate, but the advisability of 
this is as yet uncertain. 
Genus Liomesus Stinipson. Type, Buccimim dalei J. Sowerby. 
Shell bucciniform, usually solid, with a short twisted canal, smooth 
pillar and body, the outer lip thickened but not reflected, the opercu- 
lum with apical nucleus; periostracum conspicuous, often villous; the 
rhachidian tooth is replaced by an edentulous plate and the laterals 
are simple curved denticles; the ovicapsules are pouch-shaped, solitary 
and pedunculate, attached by the edge of the disk and opening at the 
top. 
Genus Beringius Dall, 1879. Type, Chrysodoinus crehricof^tatus Dall. 
Shell large, the last whorl ample, the canal short and wide; the 
nucleus subglobular, followed by a series of nearly equal turns, form- 
ing a cylindrical tip to the adult shell in most species; operculum 
small, not fully defending the aperture, somewhat arcuate, subovate, 
with apical nucleus; radula with an edentulous rhachidian plate; ovi- 
capsules large, pedunculate, resembling those of Liotnesu.'i. 
The sculpture in this group varies from smooth to fine spiral stria- 
tion and even strong spiral ribs, but no species have been observed 
with axial ribbing, unless Clu^ysodoimm kennicottii Dall should prove 
to belong to this group. 
The family Buccinidm has recently been reviewed by Cossmann^ in 
a memoir in which a large number of new names have been applied to 
fossil forms; but 1 am unable to regard any arrangement as final 
which does not take into account our knowledge of the relations of 
living species based on the anatomy, etc. 
Troschelia Morch (1876,+ Boreofxisus Sars, 1878), founded on -Fusus 
hcTniciensis^ according to the character of the radula is more closely 
related to Fusus than to any of the Buccinoid genera, though, from the 
form of the shell, often associated with the latter. 
CHRYSODOMUS TABULATUS Baird.

Chrysodonms tahulatus Baird, Proc. Zool. Soc. for 1863, p. 66. — Carpenter, 2d 
Rep. Brit. Assoc., 1863, p. 604. 
Vancouver Island to Catalina Island (in water constantly deeper 
southward) in 5 to 150 fathoms. U.S.N.M., 15503. 
This species is of a yellowish white color, often with a deeper tint 
in the throat. In its tabulated whorls it is almost unique, the only 
other form being the O. pericoddion of Schrenck, from the Japa- 
nese seas. Its analogue in the Bucchiince is found in B. hirasei Pilsbry 
and B. taphrimn Dall, for which I have proposed the section Sulcosinus.
