I took a few examples of this ground species about two miles up Papenoo valley, 
on the northeast coast of Tahiti. They were all found lurking among the roots of 
ferns. When Mr. Pea.se described it, he gave the habitat “ Tahitian archipelago,” 
and in liis list of Polynesian land shells (Proc. Zool. Soc., 1871), he erroneously cites 
“ Raiatea ” as its locality. 
Unfortunately I liave only three examples before me, so I cannot decide on its 
variation. All my duplicates, which Avere acquired by Mr. Pease, were A’ery uniform 
in shape. It may he described as an elongate-ovate, rather thin, dull brownish or 
olive-browii sliell, 18 to 20 mill, in length by 9 to 10| in diameter. The spire which 
compri.ses half the length of the shell is more swollen than in the elongate dextral P. 
Otuheitaua. Tlie parietal region is usually toothed, and the peristome is thinner, not 
so much reflected, more flattened and oblique. No banded examples occurred. 
])r. Hartman gives the wrong locality. The locality is rightly indicated on his 
chart.
