band of brownish yellow or dark brown, obliquely arranged 
round the middle, two narrow bands of the same colour 
above, separated by white, and another narrow band of 
brownish yellow or dark brown winding spirally round the 
base. The mouth is long and narrow, about seven times 
the height of the spire, the aperture being very narrow 
above and more widely open at the base, which is rounded. 
The columella has four plaits upon it. The shell is about 
g third of an inch long, and a little over a fifth of an inch 
wide.

MARGINELLA PYGMAEA (marginella, a little rim; 
pygmaea, a dwarf).—This is a charming little shell of 
about a quarter of an inch in height, with a wide, high 
shoulder to the body whorl, and shaped remarkably like 
the oil jars of ancient times, such as those in which Ali 
Baba, of the “Arabian Nights,’’ must have concealed his 
fellow scamps. It is milk white, and glistening as a dew- 
drop, resembling in general features the Fulgurarias or 
Volutes. There are about four whorls, and four plaits on 
the columella. The spire, like the lid of the oil jar, is very 
short, about one-fourth the height of the aperture; the 
body whorl tapers down gracefully to the base, the aper- 
ture being narrow above and wide below.

DRILLIA NOVZE ZELANDIE $(drillen, to bore, 
hence a drill; N.Z.)—A small, somewhat slender, spindle- 
shaped spiral univalve, found throughout New Zealand, 
but nowhere common. Of a delicate pink or pale rose 
colour, it is about one inch in length, the body whorl 
rounded, with a typical notch at the extreme base. There 
is also a notch in the outer lip, just below the suture, at 
the upper part of the aperture. The spire terminates in 
a fine point, and the sculpture consists of spiral grooves 
and fine longitudinal ribs. Some specimens are nearly 
white. 
Takapuna; Mount Maunganui; Wanganui; Wellington 
Harbour; Chatham Islands. 
BATHYTOMA CHEESEMANI (bathys, deep; tomos, 
a cutting; dedicated to T. F. Cheeseman).—Pale brown or 
purplish in colour, and about one inch in length, this small 
spiral univalve has a globular body whorl and tapering 
spire, the entire shell being fusiform or spindle-shaped.
