6. G. CEYLANICA (Pfeiffer). PL 6, figs. 7, 8. 



Shell ovate-oblong, striatulate, silky, thin, tawny-corneous; 

 spire pyramidal, the apex obtuse. Whorls 7, a little convex, 

 the last three-sevenths the total length, inflated. Columella 

 short, arcuate, abruptly truncate. Aperture rather wide, 

 semioval; peristome thin, acute. Length 16, diam. 8, aper- 

 ture 7.5x4 mm. (P/r.).

Closely related G. nitens, but the description and figure 

 indicate that the whorls are much less convex in ceylanica. 

 Colonel Beddome records specimens of ceylanica 30 x 14 mm. ; 

 but their specific identity may possibly be doubtful. 



7. G. DESHAYESI (Pfeiffer). PL 6, figs. 6, 12, 13. 



Shell turrite-ovate, rather thin, nearly smooth, glossy, 

 corneous-brown; spire long, convex, the apex rather obtuse, 

 suture simple, rather deep. Whorls 7, convex, the last two- 

 fifths the length, rounded at base. Columella somewhat 

 twisted, broadly and obliquely truncate. Aperture slightly 

 oblique, rhombic-semioval ; peristome simple, obtuse, the right 

 margin somewhat spreading. Length 11, diam. 5, aperture 

 4y 2 x2i/ 2 mm. (P/r.).

Smaller than G. nitens, and of a richer brown color, but 

 otherwise it is closely related. The whorls are strongly con- 

 vex and the surface very brilliant. Some of the upper post- 

 embryonic whorls are rather distinctly striate. The suture 

 is much less distinctly crenulated than in G. nitens, nearly
