acterizes the spire; openly umbilicated, the umbilical wall marked by 

 slender spiral threads and the axial sculpture, which is here reduced to 

 almost incremental lines. The last whorl is solute for about one-tenth of 

 a turn. Aperture broadly ovate. Peristome double, the outer moderately 

 expanded and of about the same width all around, forming a feeble 

 auricle at the posterior angle and marked by feeble, concentric lamina. 

 The inner exserted and reflected over about one-half of the outer. 

 Operculum thin, corneous, paucispiral, with the nucleus halfway be- 

 tween submarginal and subcentral, covered with a thin deposit of cal- 

 careous granules. 



The type (U.S.N.M. No. 471959) was collected by C. R. Orcutt at 

 Coteaux, Haiti. It has 4 and a fraction whorls remaining and measures : 

 Length, 14.5 mm.; greater diameter, 8.1 mm.; lesser diameter, 7.0 mm.

Plate 12, Figure 7 



Shell rather large, thin, ovate, flesh-colored, and marked with axial, 

 interrupted, distantly spaced bands of brown. Nuclear whorls decollated. 

 The postnuclear whorls are decidedly inflated, somewhat barrel-shaped, 

 narrowly shouldered at the summit, and marked on the first two turns 

 by slender, retractively curved axial riblets and equally fine spiral 

 threads, which here form a fine filelike surface. On the remaining two 

 turns this sculpture becomes very much enfeebled and the axial sculp- 

 ture almost disappears, being reduced to mere lines of growth, while 

 the spiral sculpture forms quite regular threads. The suture is narrowly 

 channeled. The periphery of the last whorl is inflated and well rounded. 

 The base is moderately long, well rounded, and marked like the spire 

 of the last whorl except that here the granulations, owing to the inter-
