the Cook’s group, about four hundred miles from its metropolis. It is also distributed 
in limited numbers throughout every valley on Tahiti, but is not found on any other 
island in the same archipelago. Its extensive range is most remarkable, and it is the 
only species known to be common to more than one group of islands.

This species only occurred to my notice in one valley, on the southwest coast of 
Tahiti, where it is abundant, lurking beneath decaying leaves and under heaps of 
loose stones. 
The type is yellowish fulvous, and invariably marked by three nazrow, revolving, 
reddish brown bands in the body-whorl, and two on the spire. The rather narrow, 
dull whitish peristome is moderately reflexed, rounded, and the margins united by a 
layer of callus on the parictal wall, which latter is edentate. It is always dextral, 
and the rather long spire equals half, or a trifle more than half, the length of the shell. 
Var a. Body deep chestnut-brown, with or without a pale sutural band, pale base 
and bilineated spire. 
Var. 6. Uniform pale fulvous or tawny, with a darker apex.

This delicate arboreal species is excessively rare, and has only occurred to my 
notice in two valleys on the west coast of Huaheine. 
It is more fragile and more robust than P. attenwata, the nearest allied form. 
The spire is less than half the length of the shell, and the suture is margined by a 
white line. ‘The dull whitish peristome is widely expanded. ‘The aperture is never 
dentate, and the yellow-corneous shell is faintly tinged with greenish. 
The animal varies from pale luteous-yellow to light brownish yellow. The soft 
parts, as seen through the transparent shell, are mottled with slate-colored spots. The 
foot is about the same length as the shell, and the ocular peduncles are very long and 
slender.
