Several specimens of a neat, white, shining Nassa, not un- 

 like the N. Cuvieri Payr. from the Mediterranean, and possibly 

 identical with N. casta Gould, an authentic specimen of which 

 we cannot find represented in our museums. The whorls are 

 seven, few ribbed, longitudinally and indistinctly spirally striate, 

 but the shell gives the impression of much brightness, whiteness, 

 and smoothness. The outer lip is denticulate within, thickened 

 without, and with two brown blotches dorsally. The columellar 

 margin is callous, white, shining. In some specimens a thin 

 brown line is seen above the sutures, in others it is absent, but 

 all have a brown ochre blotch just below the suture of the last 

 whorl, about the centre of the back of the shell. (iKo-TtXfios 

 shining).
