"ad Thyet-Mio prope fluvium Irawadi, non procul a finibus provinciae Burmanicae Britannicae" . Material examined. Bens. col., Thyet Myo", UMZC I.102845 (3 shells, type status uncertain); Pegu, Thayet-myo, "typical" , "aperture figured", NHMUK 1906.4.4.70. Remarks. Protoconch elevated, no spiral lines visible; R1 with rather regular, widely spaced ribs, and somewhat weaker spiral lines; R2 long, with widely spaced ribs; there is a lamella on each rib which is slightly bent in the direction of the anterior neighbour. Reeve (1878) named the shell figured by Hanley and Theobald (1874) on pl. 97, fig. 7, as Alycaeus microstoma , and published drawings (pl. 4, species 28). The type specimens were not examined by us, but that species was considered to be a synonym of Alycaeus sculptilis Benson, 1856 by Godwin-Austen (1914).
