Shell perforate, thin, depressed, shining, smooth above and below, color yellow-ochre above and below, with what appears to be a narrow red band at the suture caused by the overlapping of the whorls; suture very slightly im- pressed, whorls 5J regularly increasing in size, flat above, rounded below, sUghtly shouldered, outUne of the spire nearly straight, last whorl not descend- ing. Aperture oblique. Peristome simple. Columella obliquely descending, shghtly thickened, very sUghtly flattened and reflexed only within the umbilical depression. G. d. nam. 1. d. mm. alt. Fig. 5.— Fretum manni Clapp. Radula. The reddish suture-line caused by the overlapping of the whorls while noticeable in many species of Fretum, is particularly well marked in this species. The radula (Fig. 5, M. C. Z. 32,550, slide 1,639) has a formula of 40-7-1-7-40. 24. Fretum pamuaensis, sp. nov. Plate 2, fig. 1-3. Type. M. C. Z. 36,773.
