60 GLESSULA, CEYLON. 



the last whorl, and obsolete on the base. The summit is ob- 

 tuse, rounded, first whorls smooth. Whorls G 1 /^, moderately 

 convex. Suture elegantly- but somewhat irregularly denti- 

 culate. Aperture vertical; outer lip obtuse; columella very 

 short, moderately or deeply concave, subhorizontally and 

 very deeply truncate. Length 14, diam. 6, length of aper- 

 ture 5.9 mm. Length 13.5, diam. 6.1, length of aperture 

 5.9 mm.

This species differs from G. ceylanica by its very much less 

 deeply concave columella. It is a smaller and more slender 

 shell than G. serena, which seems to be its nearest ally. The 

 denticulation of the suture is a prominent feature. Though 

 "live" shells, the surface is eroded in places. The whitish 

 flecks probably will not be found on shells from stations 

 where they are less liable to erosion. 



11. G. VERUINA (Benson). 



Shell cylindric-turrite, very much lengthened, dirty whit- 

 ish, unevenly striate ; the spire gradually tapering above ; 

 suture impressed, crenulate ; apex obtuse. Whorls 12!/2 to 13, 

 narrow, cylindric, the last scarcely two-elevenths the total 

 length. Aperture vertical, truncate-oval ; peristome unex- 

 panded, acute; columella slightly arcuate. Length 25, diam. 

 5 mm. (Bens.}

This rare species has not been figured. 



12. G. COLLETS Sykes. PL 7, fig. 13. 



Shell elongate, thin, smooth, obscurely longitudinally 

 striated, brown or brown-corneous, the apex rather obtuse ; 

 suture impressed. Whorls 6 to 6%, a little convex, the last 

 half the length of the shell. Aperture nearly vertical, lunate- 

 oval, columellar margin callous, paler, obliquely truncate. 

 Length 8, diam. 2.8 mm. (Sykes).
