 Archipelagi Calamianes, leg. coll. indigena." 



[Shell narrowly perforate, almost entirely 

 covered, elevated, conical, somewhat solid, sub- 

 transparent, finely striated and decussated with 

 spiral lines scarcely visible under a somewhat strong 

 lens, shining pale yellow, ornamented with two brown 

 bands, one narrow near the suture, the other wider 

 above the periphery ; spire much elevated, almost 

 narrow laterally, apex very obtuse ; whorls, 7, first 

 5 almost flat ; penultimate whorl somewhat convex ; 

 last whorl more convex, obtusely keeled at the 

 periphery ; base swollen, gibbous, contracted behind 

 the aperture, shortly strongly deflected ; aperture 

 very oblique, truncate-elliptic ; peristome mode- 



a thread-like margin, last whorl sub-acutely keeled, 

 both sides well separated from the keel, shortly 

 but strongly deflexed in front, base slightly convex ; 

 aperture strongly oblique, lanceolate ; peristome 

 above scarcely, outwardly and below strongly 

 expanded ; base much reflexed ; columellar margin 

 strongly dilated above ; umbilicus almost covered. 



Var. apiculata, a little higher ; whorls 6, base of 

 last whorl a little more convex.] 



I figure a specimen of the type (fig. 3), diam. maj. 

 18-5, min. 17, alt. 14-5 mm., and of the variety 

 (fig. 4), diam. maj. 15, min. 14, alt. 13-5 mm.

[Shell narrowly umbilicate, almost covered, 

 trochiform, somewhat thin, transparent, obliquely 

 striate, sculptured with rather distinct spiral lines 

 and finely wrinkled oblique folds, which are 

 antrorsely decurrent, shining, pale yellowish ; spire 

 much elevated, sides sufficiently concave, apex 

 obtuse, glabrous, dark ; whorls 6J, flat, suture 

 projecting from the keel, the whorls separated by

[Shell openly umbilicated ; umbilicus equal to 

 J of the diameter; depressed discoid, thin, 

 sculptured with very thin transverse striae, very 

 close spiral lines and 

 rather strong dis- 

 tant arcuate folds, 

 covered in the folds 

 and spiral lines with 

 a very deciduous 



membranous cuticle, dark brown ; spire scarcely 

 elevated ; apex flat ; whorls 4J, somewhat flat, 

 below rather concave in the middle, almost sulcate ; 

 keel rounded, undulated along the folds ; last
