Yur. DUBIA Pilsbry. PL 38, fig. 61. 



"Rather transparent, conspicuously distantly striped with <!<<]> 

 purple-red ; whorls contracted round the upper part, then rounded ; 

 aperture small." 



Mouth of Gaboon River, W. Africa. 



This is P. strigata Reeve, 1862. I have seen neither this form 

 nor the preceding ; but they seem to me scarcely distinct from P. 

 pulla. 



P. PETITI Craven, 1882. PI. 39, figs. 84, 85. 



Shell very small, subrimate, shining, microscopically spirally stri- 

 ate ; color corneous with irregular spots of reddish brown, except 

 immediately below sutures, where they are replaced by a band of 

 alternate oblique white, cream and reddish flammules ; whorls 4i, 

 very rapidly increasing ; apex obtuse ; aperture subcircular, colored 

 inside, the same as outside ; columella a little thickened, white ; sut- 

 ure deep. There is sometimes a band of large blotches on periphery. 



Alt. 3, diam. H mill. 



Mouth of Congo River, W. Africa. 



P. DEANIANA Pilsbry, 1888. PL 64, figs. 40-43. 



Shell rather thin, ovate-conic, subtranslucent, corneous or orange- 

 colored, marked with very distinct round or oval dots of deep crini- 

 Bon, ><-;ittered over the surface or gathered around the base and 

 suture, sometimes with large maculations of opaque white ; spire 

 conic, apex acute ; whorls 5, moderately convex, often obtusely an- 

 gular and with a light or translucent girdle around the base ; aper- 

 ture ovate, slightly less than half the total length of shell, showing 

 the coloration inside ; columella thin ; generally imperforate, some- 

 times lacunate in large specimens. Alt. 5-6, diam. 3? mill. 



Corisco, W. Africa. 



This lovely little species is allied to the preceding, but differs in 

 the longer, conic, acute spire, larger size, and the pattern of colora- 

 tion. 



I am indebted to Rev. A. Dean, of Muncy, Pa., for numerous 

 specimens. 



P. VITREA Desh., 1863. PL 39, fig. 83. 



" Shell ovate-turbinate ; apex rather obtuse ; very smooth, shining, 

 polished, diaphanous- white ; whorls 6, convex, the last large ; base 

 obtuse, imperforate; aperture ovate; operculum white, solid, con- 

 vex." Alt. 7, diam. 4 mill. 



Ins. Reunion.
