Shell depressed, rather thin, slightly striated, very shining, 

 diaphanous, lemon-coloured ; spire very shortly raised, with the 

 apex acute ; suture callous, scarcely impressed ; whorls nearly 

 five, gradually enlarging, the last broader, scarcely angulated at 

 its periphery, rather flat beneath, slightly excavated near the 

 columella ; aperture oblique, lunate, modified by two teeth ap- 

 proximate to each other, one lamelliform, entering on the body 

 of the penultimate whorl, the other, which is sharp, on the 

 columella ; peristome simple, thin. Height 3, greatest breadth 

 6J, least breadth 5 mill.

6. Proserpina bidentata. B.M. 



Shell very similar to P. nitida, but much smaller ; besides the 

 deep spiral line which accompanies the suture, there are several 

 other feebly impressed spiral lines; the surface is not so smooth, 

 although equally brilliant ; the colour is yellowish-green ; the 

 aperture has only two teeth, one near the base of the columella, 

 and another a little above it. Specimens of P. pulchra, of the 

 same size, have five teeth well developed, as have also the least 

 of our specimens of P. nitida. Greatest breadth 0-21. least 

 breadth 0-13, height 0-08 inch (C. B. Adams).
