Habitat — Andaman Islands. 



Mr. Warneford collected a large series of this shell, and as, with 

 the exception of colour, there is no variation in size or texture, it 

 would seem to be a well-marked local race and possibly even a 

 distinct species. 



Melania char on, sp. nov. 



Shell elongately subulate, dark brownish black ; remaining 

 whorls 12, convex, marked throughout with lines of growth and 

 spirally sculptured with faint, somewhat distant raised striae ; 

 sutures well impressed ; columella descending in a rounded curve 

 and extending into a slight callus which reaches the lip above ; 

 peristome simple ; aperture oblong ovate ; interior slate colour.

Melania expatriata, sp. nov. 



Shell subulately turreted^ dark blackish brown ; remaining 

 whorls 4I, spirally striated on the lower half of the upper whorls ; 

 the body- whorl encircled by an infra-sutural ridge forming a distinct 

 shoulder and weakly spirally lirate throughout below the ridge ; 

 sutures impressed ; peristome simple ; columella arched, a callus 

 joining it with the lip above; aperture inversely auriform.

Habitat — Andaman Islands. 



The shoulder formed by the infra-sutural ridge presents a 

 somewhat striking appearance and recalls some of the Western 

 Pacific Island forms in which this character occurs ; the other 

 characters, however, when taken collectively or singly, easily 

 separate it from any of the species described from those regions. 



Melania multistriata, sp. nov. 



Shell decollate, subulate, dark olive brown ; remaining whorls 

 4, rather flat, sculptured throughout with fine transverse stria? 

 and coarser spiral striae ; sutures deep and incised ; columella 

 arched ; peristome acute ; aperture ovate ; interior bluish grey.
