Apex flat but slightly concave, the wliorls rising regularly. "Whorls 8, the last descends slightly near the aperture, which is very oblique and ovate. Peristome slightly reflected, white, con- tinuous on the body-whorl, but not strongly developed. Palatal. Fig. 39.—Flcciopylis oglei. teeth 6, 3rd, 4th, and 5th equal, 6th longer, double. On the parietal side is one single vertical lamina with buttress-like sup- ports on posterior side above and ; {Godwin-Axisten). Major diam. 27, minor 25 mm.; alt. 8 mm. Hub. Assam : Sadiya (Ogle). The parietal armature consists of a single strong vertical plate, which gives oft' posteriorly two short ridges, one at the upper and one at the louer extremity (see fig. 39 rf, which gives an enlarged view of a specimen with the outer wall removed). The palatal armature consistH of six horizontal folds: the first, near the suture, very short and thin; the second, third, fourth, fifth, and.
