ANCILLA AUSTRALIS var PYRAMIDALIS (ancilla, 
a maid servant; Australis, southern; pyramidal).—Ver 
similar to the species, but smaller in size, with the callus 
much thinner, the spire more sharply pointed, and the body 
whorl considerably narrower. Practically the same colour- 
ing as the species. 
Ptrintate ‘Gull. St. Helier’s Bay; Cook Strait; Nelson. 
ANCILLA BICOLOR (ancilla, a maid servant; bicolor, 
of two colours).—A rare and small shell, similar to the 
species in shape, but only about three-quarters of an inch 
long, and of a fawn colour, banded with white and darker 
brown. 
Bay or Islands; Great Barrier Island; Manukau Har- 
bour; Mount Maunganui; Queen Charlotte Sound. 
ANCILLA DEPRESSA (ancilla, a maid servant; de- 
pressed).—This species is about the same size as the A. 
bicolor, but coloured more like the A. Australis. Being 
very wide at the shoulder of the body whorl, it is not of 
such elegant proportions; in fact it is of quite a dumpy 
figure, to use a homely expression. 
Whangaroa Harbour; Hauraki Gulf; Mount Maunga- 
nui; Cook Strait; Manukau Harbour; Banks Peninsula. 
ANCILLA MUCRONATA (ancilla, a maid servant; 
mucro, a sharp point).—This species, which is larger than 
any of the other native members of the family, has a fawn- 
coloured body whorl, banded with white and pale brown. 
The spire is slightly waisted or contracted about midway 
between the apex and the top of the aperture, which gives 
the shell a somewhat pointed or mucronate appearance, 
The largest specimen I have seen is two and a-quarter 
inches in length. Some from Devonport, in Auckland 
Harbour, have quite a blunted spire on account of an ex- 
ceptionally liberal deposit of callus, so much so that the 
mucronate character is conspicuous by its absence. 
Cape Maria van Diemen; Hauraki Gulf; Mount Mau- 
nganui; Cook Strait; Cape Farewell; Queen Charlotte 
Sound. 
MARGINELLA MUSTELINA (marginella, a little rim; 
mustelina, colour of a weasel).—A small, highly-polished 
univalve, so glossy, indeed, that it is has the appearance 
of being made of coloured glass. It is elongated, barrel- 
shaped, with a rounded shoulder to the body whorl, which 
tapers slightly towards the base, and a domed spire which 
is very low; the colour is yellowish white, with a broad
