54 GLESSULA, CEYLON. 



Length 29, diam. 13, aperture 12 mm. ; whorls 8. 



Length 28, diam. 11.5, aperture 11.7 inm. ; whorls 8. 



Length 24, diam. 11.7, aperture 10.5 mm.; whorls 7J. 



The color is yellow or olivaceous, with some reddish streaks. 

 The interior is pale lilac or flesh-colored. 



This is one of the most distinct species of the genus. Col. 

 Beddome has mentioned a " var. minor, length 18 to 20 mm." 



Pfeiffer has described and figured a variety which is u more 

 distinctly striate, silky, brownish-tawny " (pi. 6, fig. 17). 

 This form is thought by Col. Beddome to be G. beddomei Blanf. 



2, G. LANKANA Pilsbry, n. sp. PI. 7, figs. 1, 2, 3. 



Shell oblong-turrite, thin but rather solid, yellow or tawuy, 

 with some narrow darker or chestnut streaks on the spire. 

 Surface very glossy, finely and deeply striate, the strise unequal, 

 in places being as narrow as the intervals, but occasionally much 

 wider. Under the compound microscope a very faint spiral 

 striation is visible, the spirals being very weakly beaded in 

 places. The first 2 whorls are smooth. Spire conic with 

 straight sides and' obtuse apex. Suture irregularly crenulate. 

 Aperture vertical, flesh-tinted inside. Outer lip obtuse, form- 

 ing a regular arch. Columella moderately concave, obliquely 

 truncate at base. 



Length 27.2, diam. 11, length apart. 10 mm.; whorls 8J. 



Length 27, diam. 11.2, length apart. 10.5 mm.; whorls 8J. 



Ceylon: Matella District (Layard). 



Closely related to G. inornata, but more glossy and having 

 much less distinct microscopic granulation, as may be seen by 

 comparing fig. 3 with pi. 6, fig. 16. The outlines of the spire 

 are straighter; there are more whorls in the same length, and 

 the aperture is smaller. G. beddomei has a more prominent 

 and more deeply truncate columella. 



3. G. PARABILIS (Benson). PI. 7, fig. 4. 



Shell oblong-ovate, rather solid, glossy, rugose-striate, decus- 

 sated with most minute, obsolete spiral striae, whitish under a 

 buff-corneous cuticle. Spire long-conic, the apex obtuse, suture 

 lightly impressed, subcrenulate. Whorls 6, subplanulate, the 

 last a little convex, scarcely three-sevenths the shell's length.
