whorl, more attenuated at the base, with the whorls 'of the spire more con-

 faintly stained with light-brown at the extreme base.

MARGmELLA (GlABELLA) PICTURATA, n. Sp. 



Shell small, rather thick, resembling a miniature M. gemma^ A. Ad. 

 (^=f estiva, Rv. var.) whorls six, spire conically exserted ; rufous-brown, 

 throughout indistinctly mottled, round the centre a rather broad white 

 band and row of distant, regular, square, dark-brown spots, a second less 

 distinctly marked band near the base of the last whorl ; columella regularly 

 four-plaited, aperture straight, very narrow, outer lip much thickened 

 and reflexed, marked with three brown spots.

MaEGINELLA (VoLYARIIfA) INCONSPICUA, n. sp. 



This small species belongs to the same group as the succeeding, both 

 being allied to M. neglecta, Sow. ; shell white, shining, smooth, whorls three 

 to four, the last one contracted at the base, swollen above ; margin of the 

 outer lip slightly flexuous, two upper plaits on the columella small and 

 transverse, the two lower ones large and nearly perpendicular.

Marginella (Volyariita) deformis, n. sp. 



This small shell resembles no species of the genus known to us, 

 except M. suavis, Souv., Journ. de Conchil., 1858, p. 376 ; the present species, 

 however, differs in not having its last whorl as regularly cylindrical, but 

 abruptly inclined to one side, making the aperture shorter and more con- 

 tracted, and giving the shell a somewhat deformed appearance ; the two 

 lower plaits on the columella are of a different character, instead of being 

 nearly transverse, as are the two upper ones, they are almost perpendicular ; 

 on the last whorl instead of three, there are only two pink bands, both very 

 broad, the band on the upper whorl is also just above the suture, not beneath it.

CITHA.RA AMABILIS, n. Sp., PI. I. Fig. II. 



Shell small, oblong, fusiformly ovate, spire short ; whorls seven, longitu- 

 dinally strongly ribbed, ribs rather distant, on the last whorl unusually 

 convex, these ribs, on the last three whorls, are formed of swollen, almost 

 spherical granules, on the two apical whorls they are very small, colourless 

 and without sculpture, on the other two the ribs are also colourless, but with
