The original locality given by Pease, "Roratonga, " was an 

 error on the part of Pease. Garrett, who supplied the types 

 to Pease, states that he collected them on Aitutaki. 



The shell is oblong, somewhat cylindroid, cinnamon-brown, 

 opaque, with little gloss. Surface is densely pitted, with un- 

 evenly developed oblique striae or traces of them, strongest 

 below the suture. Whorls convex, the last having a long, 

 somewhat oblique furrow in the upper palatal position, ter- 

 minating at the lip. The peristome is well expanded and 

 thickened within except at the sinulus, colored like the out- 

 side. The rather long angular lamella is straight within, 

 anteriorly curving outward and joining the lip some distance 

 from its insertion. Parietal lamella about as long as the an- 

 gular, more immersed, somewhat curved. The columellar 

 lamella is deeply placed, small in a front view: below it is a 

 small immersed subcolumellar lamella, visible in an oblique 

 view. There are three rather short, deeply placed palatal 

 folds, the iuterpalatal a little shorter, the lower palatal nearly 

 basal in position. The upper palatal, foreshortened in the 

 figure, is moderately long, laminiform. 



Length 2, diam. 1.15 mm.; length of aperture 0.8 mm.; 5 

 whorls.

 the Pease collection, no. 48314 Mus. Comp. Zool. The shells 

 were quite dirty, this doubtless accounting for the discrepan- 

 cies between Pease's description and that now given.
