Spira depresso-conica, lateribus concavis, apice papillari, magis exserto, sutura profunda. Anfr. 5, convexi, ultimus magnus, ad peripheriam angulatus, angulo antice evanescente, subtus convexus, juxta aperturam leniter descendens. Apertura fere rotunda, obliqua, lutescenti-albida, aliquantulum latior quam alta. Peristoma rectum, incrassato-ex-pansum, subcontinuum. Umbilicus pervius. Operculum normale. Diam. maj. 46, min. 38, axis 25 m m ; apert. cum perist. 23 m m. lata, 21 \ alta. Hab. haud procul a Bhamo, ad ripas fluminis Iravadi. Somewhat allied to C. pearsoni, Benson, and C. excellens, Pfr., but more depressed than either. It is distinguished from C. theo-baldianus, Bens., by its much smaller mouth and smoother surface. 7. SPIRACULUM ANDERSONI, sp. nov. Testa late umbilicata, depressa, discoidea, oblique striata, lineis minutis spiralibus superne et prcesertim juxta peripheriam, sed non circa umbilicum, confertissime decussata, albida, strigis castaneis fulguratis radiantibus picta. Spira plana, apice vel piano vel vix exsertiusculo, sutura profunda. Anfr. 4\, teretes, ultimus versus aperturam longe descendens, 5-6 mill, pone peristoma tubulo suturali reverse parvo, arcuatim recurvaito vel subrecto et libero, 2-3 mm. longo munitus. Apertura diagonalis, rotunda; peristoma continuum, duplex, internum expansiusculum undique appressum, postice juxta anfractum penultimum profunde angulatim sinuatum, externum expansum, supra sinum dilatatum, juxta anfractum penultimum instar cuculli plani porrectum. Operc. persimile ei Sp. hispidi, corneum, intus concavum, extus convexum, marginibus anfractuum, prcesertim externorum, lamel-latim liberis, apice planiusculo. Diam. maj. 15|-17, min. 12-13|, axis 5-6, apert. diam. intus 5 m m. Hab. ad Bhamo cum praecedente. Distinguished from Sp. avanum, W . Blanf., by its more oblique mouth, differently shaped and more expanded peristome, by the horizontal cowl-shaped projection running forwards along the last whorl instead of being vertical, the greater distance of the sutural tube from the mouth, and the much more convex operculum. 8. HELIX (TRACHIA) CATOSTOMA, sp. nov. Testa late umbilicata, depressa, subdiscoidea, cornea, tenuis, striata. Spira depresso-convexa, sutura leviter impressa. Anfr. 7, convexi, arete convoluti, ultimus rotundatus, circa umbilicum subcompres-sus, antice abrupte deflexus, valde descendens, pone aperturam subconstrictus. Apertura fere horizontalis, truncato-ovata; peristoma album, refiexum, antice et postice prope anfractum penultimum arcuatum, marginibus subdistanter convergentibus, callo tenui junctis; umbilicus latissimus, pervius.
