[Plate IX.] 



Pleurodonte (Caracohis) manifesta^ sp. n. 

 (PI. IX. H- 10.) 



Shell very slightly port'oratc, solid, depressed, light yellowish 

 brown, almost covered by two very dark spiral bands, one 

 broad one in the middle ot" the whorl and the other just below 

 the suture, apex much lighter in colour; whorls 5, veiy 

 convex, first three finely reticulated, the penultiuiate and 

 upper part of last whorl sculptured with very coarse granular 

 spiral sculpture, underside of body-whorl almost smooth, 

 having only oblique growth-lines, and being ornamented by 

 one dark spiral band about 2 mm. wide situated about the 

 same distance from the periphery ; the upper wall of the last 

 third of body-whorl is swollen and ascends to the middle of 

 the penultimate whorl, descending rather suddenly a little 

 distance from its termination ; aperture very oblique, white 

 within except parietal wall, which is yellowish and on which 

 the colour-band is continued ; peristome thickened and very 

 narrowly expanded, white, margins connected by a white 

 raised callus. 



Maj. diam. 32, alt. 17 mm. 



Bab. ? (probably Cuba). 



This shell, of which I have two specimens before me, is 

 readily distinguished by its strong granular sculpture and the 

 prominent swelling situated behind the upper margin of the 

 peristome : Jactuta, Gundl., has the same kind of sculpture, 

 but in that species it is very fine and scarcely seen without a 

 lens ; vianifesta also differs by its darker coloration and the 

 greater convexity of its whorls. 



In Tryon's ' Manual of the Mollusca,' ser. 2, vol. y.,jactata 

 (Gundl., Mv5»S.), Pir., is put as = »<i«a, Ptr. ; but on examin- 

 ation of a large series of mina I cannot find any with the 

 granular sculpture characteristic oijactata. 



Planispira cingarus, sp. n. (PI. IX. fig. 8.) 



Shell discoidal, umbilicus about 2 mm. wide at opening, 

 spire fiat, light below, dark brown above, with a darker supra- 

 peripheral band about 1 ram. wide encircling the body-whorl.
