nearly 6, very convex, the last flattened below the suture, else- 

 where well rounded. Aperture circular, somewhat oblique, bluish 

 and showing the bands inside; peristome rather narrowly reflexed, 

 its face rounded, faintly red-tinted or bright red, continued in a 

 callus across the very short parietal wall; the columellar margin 

 overhanging and partially concealing the small umbilicus. 



Alt. 30, diam. 32 mm. ; antero- posterior diameter of aperture 

 21, width 191 mm. 



Alt. 29, diam. 31 mm. ; antero -posterior .diameter of aperture 

 20^, width 19 mm. 



Operculum circular, multispiral, concave externally; diam. 

 15^ mm. 



Oshima, (Mr. Y. Hirase, No. 644). 



Related to C. jourdyi Mori., fulguratus Pfr., courbeti Anc., and 

 their allies, species of Tonquin and Burma. It is remarkable for 

 its elevated spire and brilliant peristome. 

 Pupinella oshimae n. sp. 



Shell pupiform, dark purplish brown under a papery whitish outer 

 color, apparently the result of weathering, densely and finely striate 

 when unworn. Whorls 6, slightly convex, the first four forming 

 a conic spire, the penultimate and last whorls of about equal diam- 

 eter ; last whorl somewhat produced forward below. Aperture 

 vertical, the opening small and circular; peristome broadly reflexed, 

 white or nearly so, very heavily thickened on the face, produced 

 forward in a flange around the opening, interrupted by minute 

 channels at the base of the columella and posterior end of the lip, 

 these channels expanding funnel-like outwardly; parietal callus 

 very strong at its right end, emitting a branch which rises high 

 above the termination of the outer lip. 



Length 10, diam. 4.8 mm.; diam. of aperture, inside of peris- 

 tome, 2.2 mm. 



Oshima (Mr. Y. Hirase, No. 645). 



This species differs strongly from P. rufa Sowb. and its slightly 

 differentiated local forms fnihstorferi and tsushimana, in the rela- 

 tively enormous development of the peristome, reducing the open- 

 ing of the aperture; in the vertical, not oblique plane of the aper- 

 ture, and especially in having the tongue of the parietal callus 

 defining the posterior canal, very much longer, rising high above 

 the termination of the outer lip. The latter is abruptly truncated
