12 SHELLS FROM THE MOLUCCAS, 
d. nearly white, with band 4 and sometimes with traces of 
other bands. 
e. like the preceding, but only with band 3. 
f. like the preceding, with bands 3 and 4. 
g. brown or yellowish white, or yellow without bands or 
with very faint ones. 
h. subvar. albina; white with a yellowish tint. 
All these variations are connected by intermediate links. 
Martin has collected at Wahaai, Ceram, a very fine 
variety , which does not agree with any other, and which 
I must consider as new. I name it after its discoverer 
var. Martini. 
(Plate 3, fig. 2). 
Shell small, much depressed, with a more transverse- 
oblong aperture, peristome widely expanded, last whorl 
commonly but slightly deflected. The shell is transparent, 
horny, with one dark brown peripherical band (n°. 3) often 
occupying only the second part of the last whorl; above 
and below the surface is adorned with alternating trans- 
parent and opaque white bands; space near the umbilicus 
uninterruptedly pellucid (one specimen has a broad brown 
band along the suture and two narrow ones between this 
and the peripherical one).

Prof. v. Martens calls the colour of his var. fasciata, 
the only one collected by him at Wahaai, pure white, 
while this new variety is remarkable by its transparency 
in fresh specimens. Moreover only one specimen agrees 
with the measurements. It may have many affinities with 
var. B. of Tapparone Canefri (Ann. del Mus. Civ. di Storia 
nat. di Genova, 1883, p. 152), but the umbilicus is not 
larger than in other varieties.
