76. G. LATESTRIATA Moellendorff. 



Shell rather ventricosely oblong, rather thin, subpellucid, 

 peculiarly sculptured with rather distant impressed striae, 

 corneous-yellow. Spire moderately long, the sides a little 

 convex, apex somewhat acute. Whorls 7, moderately convex, 

 separated by a well-impressed, subcrenulate suture. Aper- 

 ture nearly vertical, roundly-rhomboidal ; peristome unex- 

 panded, obtuse; columella rather twisted, abruptly truncate. 

 Length 10, diam. 4.5, aperture 3.5 x 2.25 mm. (Mlldff.)

77. G. PAVIEI L. Morlet. PI. 12, figs. 7, 8. 



Shell imperforate, elongate, subturrite, thin, glossy, trans- 

 lucent, pale corneous, ornamented with radiating striae. Spire 

 subconic; whorls 8, a little convex, the first obtuse, following 

 separated by a simple suture, a little inflated at the suture, 

 the last whorl moderately inflated, over one-third the total 

 length. Aperture suboval, columella short, very deeply arcu- 

 ate, twisted and truncate; columellar callus thin; lip regu- 

 larly arcuate. Length 14, diam. 6, aperture 5 mm. long.

 pi. 7, f. 4; Mission Pavie, Indo-Chine iii, p. 359, pi. 19, 

 f. 13 (1904). 



Two embryonic whorls are smooth, the last becoming 

 crenulate below the suture. The following whorls are 

 grooved at unequal intervals, the grooves strongest near the 

 upper suture, weakening near the lower. The last whorl has 

 rather close grooves and wrinkles. This sculpture is visible 

 only under a lens. The columella is only moderately eon- 

 cave in specimens I have seen, and is very obliquely trun- 

 cate. The outer lip is whitish, a little thickened and obtuse, 

 as usual in adult Glessulas. A specimen from Muong-Lai
