the surface is eroded iu places. The whitish flecks will probably 

 not be found on shells from stations where they are less liable to 

 erosion." (Filshnj.)

Original description : — "A. testa turi'ito-ovata, tenuiuscula, sub- 

 laevigata, nitida, corneo-fusca ; spira elongata, convexa, apice 

 obtusula ; sutura simplice, subprofunda ; anfractibus 7 convexis, 

 ultimo I longitudinis subaequante, basi rotundato ; columella 

 subtorta, late et oblique truncata ; apertura vix obliqua, 

 rhombeo-semiovali ; peristomate simplice, obtuso, margiue dextro

 Mountains, Calicut (Pfeiffer). 



Pilsbry notes " smaller than G. nitens, and of a richer brown 

 colour, but otherwise it is closely related. The whorls are 

 strongly convex and the surface is very brilliant. Some of the 

 post-embryonic whorls are rather distinctly striate. The suture 

 is much less distinctly crenulate than in G. nitens, nearly simple. 

 The sides of the spire are slightly convex." 



The British Museum possesses three specimens, received from 

 E. L. Layard, from Pt. Pedro, in the extreme north of Ceylon ; 

 these have seven whorls and measure 12 x 6 mm. There are also 

 some specimens in the Cuming collection bearing Pfeiffer's own 

 label ; they are from Koondah, Calicut. The base is rather 

 narrow and the shells are of a paler colour than the typical form ; 

 they are also composed of seven whorls but, like the type, only 

 measure 11 xo mm.
