24 SPECIES OF PAPUINA, PLANISPIRA, STROPHOCHEILUS AND DRVMAEUS. 



S. .■4inifarnr:i, Orb., described in the "Mag. de Zool," 1835. Moll., 

 p. 15, and figured in the " Voyage dans L'Amerique meridionale " p. 302, 

 t. 38, figs. I, 2, is a much smoother shell, the two lower nepionic whorls 

 are sculptured with fine close-set raised striae, and the post-nepionic whorls 

 are covered with a fine spiral granulation. 



The lower nepionic whorls of rw/o>;us have rather distant strong radial 

 riblets, the jjenultimate whorl is granulated, but the last has no granulation, 

 but strong rugose oblique striae or lines of growth. 



Comparatively speaking, r?<;/o.s7/.s' is a rough-looking shell, while 

 ,-<a/ifami~.i is a smooth one. 



Strophoeheilus (Bonis) versatilis, n. sp. 



PL vi, fig. I. 

 Shell almost imperforate, the opening consisting of a slight chink, oblong- 

 ovate, solid, yellowish-brown with darker oblicjue stripes, spire short ; whorls 

 5^, moderately convex, the first two smooth, the next i^ having rather 

 distant, strong, oblique riblets, the middle whorls finely granulated, the last 

 conspicuously malleated, more especially on the last half-whorl, nepi(Miic 

 whorls 3^ ; aperture narrowly ovate, whitish within ; peristome white, thick- 

 ened and rather expanded, slightly depressed at base of columellar margin, 

 right margin suddenly thickening about half-way down, causing a somewhat 

 tubercular-like projection ; a thick white callus over the parietal wall con- 

 necting the margins of the peristome.

i^a?^.— (Brazil ?). 



This partakes of the characteristics of several known species ; in form 

 it is similar to aurltus, Sowb., the sculpture of the middle whorls is like that 

 oi cantanallanm, Rang., and its nepionic and last whorls have similar sculp- 

 ture to that of bronni, Pfr. 



Strophoeheilus (Bonus) semimalleatus, n. sp. 



PI. vi, fig. 2. 



Shell imperforate, solid, oval, yellowish-brown cuticle below, reddish-brown 

 above ; whorls neady 6, first one smooth, the next three with rather con- 

 spicuous close set oblique striae, last whorl with more distant, irregular lines 

 of growth and plainly malleated, slightly ascending at its termination ; 

 aperture oval, light- brown within ; peristome thickened but expanded only 

 at the coUumellar margin, white, continued across the parietal wall by a 

 white callus connecting the right margin. 



Maj. diam. 51, alt. 90 millim.
