and in crevices at low-water mark; it is local in distribution.

GIBBULA SUTERI (gibbula, dim. of gibbus, a hump; 
Suter, the conchologist).—A very small and thin univalve, 
found living on seaweed. It is of a grey, brownish-grey, 
or pinkish colour, with patches of blue iridescence in some 
specimens, sometimes varied and chequered with white, 
especially on the periphery or widest part of the body 
whorl, which may have conspicuous and equidistant patches 
of white. Suter states that the colour markings are very 
often like those of Photinula nitida. The sculpture con- 
sists of very fine spiral lines, crossed by equally fine 
growth lines. The outer lip is thin and sharp, lined with 
a narrow band of silvery callus. It is about three-sixteenths 
of an inch in height, and the same in diameter.

MONILEA EGENA (monilea, a necklace; egena, desti- 
tute).—A small spiral univalve, about five-sixteenths of 
an inch in diameter, of an ashy-grey-white colour, with 
longitudinal streaks of light brown, which form zigzag 
bands on the body whorl. The sculpture consists of deep 
spiral grooves between well-defined sharp ribs, four on the 
body whorl and three on the whorl above; the two upper 
ribs of each being slightly beaded. The under surface of 
the shell is white, and shows a widely-open funnel-shaped 
umbilicus surrounded by a beaded brownish band. The 
protoconch is sharply pointed, brown in colour, smooth and 
polished; while the upper whorls of the spire are usually 
worn and show the pearly nature of the shell. It is no- 
where common, and lives below low-water mark in sandy 
places. Washed ashore after stormy weather.

Lyall Bay; Stewart and Chatham Islands. 
CALLIOSTOMA PELLUCIDUM (halos, beautiful; 
stoma, the mouth; pellucid).—A slightly-waisted, sharply- 
pointed, and rather thin spiral univalve, of a pale yellow 
colour, mottled with reddish chestnut, disposed in oblique 
longitudinal irregular bands or blotches. Sculptured with 
numerous small finely-beaded spiral ribs. The body whorl 
is distinctly angled at the base, which is rather flattened; 
the columella, which is pearly, ends at the extremity in a 
slight tubercle or knob. The interior is pearly. It attains 
a height of one and a-half inches and is of similar dia-
