 maining and measures : Length, 18.6 mm. ; greater diameter, 12 mm. ; 

 lesser diameter, 8.5 mm.

Shell elongate-conic when complete, flesh-colored with interrupted 

 spiral zones of brown. Some of these zones are fulgurated, others merely 

 elongated dots, and still others of these dots are joined into bands, while 

 the one below the periphery is most conspicuous and broader than the 

 rest. The base is also marked by interrupted bands, though less con- 

 spicuously so than the spire. The inner peristome is white, while the 

 outer is slightly rayed. Nuclear whorls 2, straw-colored, strongly 

 rounded. Postnuclear whorls well rounded, marked by slender, slightly 

 retractively slanting axial riblets, which are about as wide as the spaces 

 that separate them and which render the summit of the whorls feebly 

 crenulated. Suture moderately constricted; periphery somewhat inflated, 

 strongly rounded. Base narrowly umbilicated, somewhat inflated, strongly 

 rounded, and marked by the continuation of the axial riblets. The 

 columellar wall of the umbilicus is marked by few obsolete spiral threads 

 near its outer margin. The last whorl is slightly solute. Aperture ovate; 

 peristome double, the inner projecting slightly above the outer and 

 slightly expanded; the outer slightly expanded, more so on the outer 

 and basal lips than on the columellar border, where it is only about 

 one-third as broad as on the rest. Operculum thin, corneous, typically 

 chondropomoid. 



The specimen described and figured (U.S.N.M. No. 403919) was 

 collected by Dr. Wetmore on Beata Island. It has 3.5 whorls and meas- 

 ures : Length, 14 mm. ; greater diameter, 9.4 mm. Some specimens are 

 considerably larger than this, one with 4 whorls measuring: Length, 

 18 mm.; greater diameter, 11.2 mm.
