(JbESSULA, CEYLON. 53 



I. SPECIES OF CEYLON. 



The Ceylonese Glessulre are closely related to those of southern 

 India, and in a few cases seem to be of identical species. Such 

 cases should receive very careful comparison. The following 

 forms, described from Peninsular India, have been identified by 

 reliable authorities from Ceylon. 



G. beddomei Blanf. , No. 34. 



G. sattitraeiui* ' H. Ad.' Hanley & Theobald, No. 49. 



G. pusilla Beddome, No. 52. 



1. G. INORNATA (Pfeiffer). PI. 6, figs. 10, 11, 14-17. 



Shell turrite-oblong, solid, closely striate; pale tawny, varie- 

 gated with darker streaks; nearly lusterless, having a woody 

 appearance. Spire turrite, the apex rather obtuse, suture lightly 

 impressed, very closely crenulated. Whorls 7^, rather flattened, 

 the last nearly equal to two-fifths the total length, the base 

 slightly compressed and smoother. Columella very deeply 

 arcuate, white-calloused, obliquely, abruptly truncate. Aper- 

 ture sinuous-semioval, white within. Peristome simple, obtuse, 

 the right margin spreading. Length 28, diam. 11, aperture 

 11.5x5 mm. (Pfr.). 



Ceylon (Pfr.): Kandy (Nevill, Simon); Matelle East and 

 Ma Ellia (Layard). South Canara forests (Beddome).

The first 2 whorls seem to be nearly smooth, but with a 

 finely crenulate suture; then fine, distinct strise begin, strongest 

 near the suture, weaker below. On the spire these stria? are 

 separated into groups by occasional deeper grooves or larger 

 striae; and more or less trace of such irregularity may often be 

 traced on the last whorl. Under the compound microscope, 

 the surface is seen to be very densely covered with minute granules 

 arranged in spiral lines (pi. 6, fig. 16). These give it a charac- 

 teristic silky sheen, unlike the smooth species. Specimens 

 before me measure as follows, all being adults with the lip blunt.
