or at somewhat irregular intervals. On the last two or three 

 whorls the striation is still coarser, and chiefly on the upper 

 part of each whorl, the lower part being much smoother. 

 Specimens from Poona before me are more slender than those 

 from Bombay, measuring 21 x 7 mm., with 10^2 whorls. 



The sculptured embryonic whorls show that this species is 

 not related to G. tenuispira. I am much inclined to doubt 

 that the specimens recorded from the Sylhet region are really 

 notigena. They are probably tenuispira.

Shell turrite, rather solid, smoothish, corroded in dots, pale 

 corneous. Spire a little convexly turrite, rather acute; su-

 base. Columella very deeply arcuate, obliquely distinctly 

 truncate. Aperture slightly oblique, sinuate-semioval ; peris- 

 tome simple, thin. Length 15, diam. 4%, aperture 4x2 mm.

Shell oblong-turrite, thin, slightly striatulate, glossy, sub- 

 pellucid, tawny-corneous. Spire somewhat turrite, the apex 

 rather obtuse; suture subimpressed, closely denticulate.

 the total length, tapering at the base; columella slightly 

 arcuate, shortly truncate a little above the base of the semi- 

 oval aperture; peristome simple, acute, the right margin 

 slightly arcuate. Length 18, diam. 6%, aperture 6% x 3,
