152 BUCCINIDA. 
dark brown epidermis, sometimes translucent, covers the living 
shell, but cabinet specimens are usually denuded of this, exhib- 
iting upon an ivory-white surface, spots and maculations of 
orange-red. The aperture is usually white, sometimes tinged 
with violet upon the columella. This pattern of coloring is most 
uniform throughout the genus ; but the species are distinguished 
by modifications of the arrangement of the color-spots, as well 
as by the differences of shoulder and umbilicus. None of the 
species are strictly banded, although in some the coloring coal- 
esces into irregular revolving masses. The coloring reminds 
one strongly of Phasianella, whilst the shell, except for the want 
of its characteristic groove and tooth, recalls the genus Pseudo- 
liva—one of the species of which was formerly erroneously 
referred to this group. The surface of the shell is invariably 
smooth, devoid of the sculpture of ribs, striz, tuberculations, 
etc. The operculum is ample, filling the aperture. The Eburne 
are natives of the tropical seas of the Eastern hemisphere. 
ZEMIRA, H. and A. Adams. Umbilicus moderate; outer lip 
with a tooth near the fore-part. The revolving channel near the 
base of the shell, ending in a tooth-like projection on the outer 
lip, has induced Sowerby to class this species in the genus 
Pseudoliva; it seems nearly related to Eburna, however. JL.

Shell ovate, solid, with a thick epidermis ; spire elevated ; colu- 
mella wrinkled, with a callosity at the upper part ; outer lip thin, 
with a small tooth anteriorly. Operculum ovate, with apical 
nucleus. 
This was originally described as a subgenus of Pseudoliva, 
which it resembles in having an inferior revolving groove termi- 
nating in a small tooth-like projection of the outer lip; the 
operculum, however, is unguiculate like that of the Eburne, 
whilst that of Pseudoliva is purpuroid. The more decided canal 
and absence of sutural channel, and the rather persistent blackish 
brown epidermis, will distinguish it from the subgenus Zemira 
of Eburna. Its locality, West Coast of America, is also a 
distinctive character; Eburna being East Indian, and Pseudo- 
liva African in distribution.
