1877.] Upper Burma and Yunnan. 35 



Paludomus Andersoniana, n. sp. 



Large and globose ; spire produced and pointed ; of a very striking 

 greenish yellow colour, with four intense black bands on the last whorl, the 

 one at the suture and the two near the base about the width of the broadest 

 band on P. ornata ; the second band from the suture twice this width, this 

 latter, in all but very old specimens, is very distinctly visible within the 

 aperture ; whorls seven, the first two or three generally decollated, trans- 

 versely 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 jDortion and by the distinct, though minute, 

 granular margin. Dr. Anderson obtained several hundred specimens in all 

 stages of growth at Mandalay, Ava, Bhamo, Kabyuet, and Myadoung. One 

 of the best distinguishing marks from its var. Peguensis is the great width 

 within the aperture of the second brown band ; the band nearest the base, 

 on the other hand, is comparatively smaller ; in P. Peguensis (even in 

 young specimens) the two upper bands are altogether wanting, the third 

 very narrow, the last broad and diffused over the basal portion of the colu- 

 mella. This is probably the Paludomus sp. of Theobald from the Shan 

 States, J. A. S. B., 1865, p. 264. 



Long. max. 29, diam. max. 22 mil. 



Var. Peguensis (an sp. n. ?) 

 Paludomus regulata, Bens., var., Con. Indica, pi. 108, fig. 6. 



Differs from the preceding by 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. Unfortunately, all the speci- 

 mens have lost their opercula. The specimen figured in the ' Con. Indica' 

 is a very old decollated one. 



Type of variety from Pegu, long. 21, diam. 16 mil. 



Paludomus oenata, Bens. 



Faludomus ornata, Bens., A. & M., 1856, 498 ; Con. Indica, pi. 108, fig. 8. 



Specimens of this very handsome species from Ava, Pegu, and Manda- 

 lay are in the Museum Collection ; it is well characterized by its seven 

 produced and solid whorls, acute and prominent spire ; the Ava specimens 

 are not decollated, though quite adult ; those from the other two localities
