this latter, in all but very old specimens, is very distinctly visible 

 within the aperture ; whorls seven, the first two or three generally 

 decollated, transversely superficially ridged, ridges more or less 

 obsolete towards the centre of the upper whorls, one of them 

 below the suture more prominent than the rest ; columella pure 

 white ; the operculum constantly differs on its inner side from 

 those of the other Burmese species by the remarkably raised and 

 very rugose nucleolar portion and by the distinct, though minute, 

 granular margin.

 Paludomus regulata, Benson, var., H. & T., C. I. pi. 108, fig. 6. 



Original description : Differs from the preceding [P. anders- 

 sonicoia]l>y the slightly more rugose sculpture, by its more decollated 

 apex, by the less cylindrical whorls and less produced and pointed 

 spire (more apparent in young specimens), by the columella being 

 apparently invariably faintly stained with brown, by the almost 

 entire apparent absence of colouration on the last whorl, especially 

 in the absence of the second broad band within the aperture.
