SHELLS FROM THE MOLUCCAS. 151 
var. lineolata Martens. 
The specimens from the last-named locality agree for 
the greater part with pl. 16, fig. 6 of v. Martens; other 
ones are smaller and less marked with the greyish spots, 
they have the bands 3 and 4, if one of them is lost it 
is the Srd; other specimens are quite destitute of bands. 
One very remarkable specimen is distinctly keeled by a 
prominent rounded keel near the base and it has a second 
one near the umbilicus. I am, however, convinced that it 
is only a monstrosity, perhaps caused by some wound of 
the soft parts, while in the act of building the shell. 
The specimens from Porto, Saparoea, belong to this 
variety by their colours, though in shape they come near 
to var. nitidiuscula Boettg. Those from the neighbourhood 
of the kampong Saparoea have the shape of var. nitidius- 
cula, but they are slightly flattened; many of them have 
the same pattern as var. lineolata, but the lustre of var. 
nitidiuscula, some are banded and others without bands, 
even nearly white; they pass imperceptibly into 
var. nitidiuscula Boettger.

From the kampong Saparoea. A few specimens, one brown 
or yellowish white, with one or two bands, and one spe- 
cimen without bands. 
Another specimen from Aboro, Haroekoe, is yellowish 
white, with the bands 3 and 4. 
A large number from Porto, Saparoea, also collected 
by Baron van Hoévell, shows a great diversity of colours 
and markings; the chief variations are: 
a. more or less dark brown, with the bands 3 and 4 or 
one of them. 
b. under part of shell nearly white, the upper part with 
obsolete flames; bands 3 and 4 or one of them. 
c. like the preceding, but the space between the suture 
and rd band chestnut-brown.
