Helicina flammeata, Muhlfeldt, MS., 1. c. (Ex. Pfeiffer.) 
This small species is confined to Tahiti and Moorea, where it lives beneath decaying 
vegetation. 
Sowerby’s type .specimens were collected by Cuming at Rurutu = “ Oheatora,” 
one of the Austral Islands. 
Some e.xamples exhibit the delicate pilose fugacious striae as mentioned in my 
remarks on inconspicua and flavescena. The color is reddish brown, straw-yellow, 
corneous or dull reddish. 
Major diam. 4^ mill.

Helicina albolabris, Carpenter (not of Homb. and Jacq.), Proc. Zool. Soc., 1864, p. 673. 
A somewhat .scarce species, found only at Tahaa, where it lives on the ground in 
the lowland forests. 
hen Mr. Pease described this species he gave the correct locality ; but in his 
catalogue of Polyne.sian land shells he give, the wrong habitat, “ Tahiti,” where it 
does not occur. 
It has the sulcate base of corrugata, but is more depressed, and the upper surface 
of the whorls is more or less corrugated by coarse transverse ribs or undulations, 
r le periphery is carinated, and the color is dull reddish brown, rarely pale yellowish
