96 GLESSULA, NON-PENINSULAR INDIA TO INDO-CHINA. 



The outer lip is a little sinuous, being retracted above; it is 

 moderately thickened or obtuse. 



Col. Beddome considers this species identical with G. facula.

"Shell turrite-conic, smooth, corneous, longitudinally 

 striated. Whorls convex, suture excavated; lip thickened 

 within ; columella very deeply arcuate ; apex obtuse. Length 

 0.7, diam. 0.3 inch." (Benson). 



Length 18, diam. 8, aperture 7.5x4 mm., whorls 8 (Pfr.). 



The shell is ovate-oblong, yellow. The embryonic whorls 

 are smooth, a little over two. Subsequent sculpture consists 

 of rather close grooves, most prominent at the suture, which is 

 rather deeply impressed, though the whorls are only moder- 

 ately convex. The suture descends a little near the lip. The 

 aperture is rather small, outer lip decidedly obtuse, thick- 

 ened, its rounded edge bicolored, white and yellow. The 

 outer lip is slightly retracted in the upper part. Length 20.5, 

 diam. 9.5 mm., whorls 6% (fig. 15).

Godwin-Austen (1875) considered pyramis, butleri and il- 

 lustris as subspecies of G. crassilabris. The latter is de- 

 cidedly more robust than illustris, which belong to a differ- 

 ent group ; pyramis and butleri are both more elongate shells.

Shell ovate-oblong, rather solid, smooth, lightly striate, 

 sculptured with a few rather widely spaced, deeply impressed 

 strise; glossy, olive-corneous. Spire convexly pyramidal, the 

 apex obtuse, suture impressed; whorls 6^2 to 7%, a little 

 convex, angulated at the shoulder, crenulate, the last over 

 one-third the total length. Aperture vertical, semioval;
