 NoRRis's Volute. Shell somewhat squarely ovate, ven- 

 tricose, spire short, rather obtuse aud uoduled at the 

 a])ex, whorls smooth, concavely angled round the 

 upper part, spinosely squamate at the angle, colu- 

 mella slightly arched, four-plaited ; yellowish and 

 greenish, two-banded round the midtUe aud stained 

 at the upper part with short blackish Mues in olive- 

 green blotches, ai-eas between the bands sparingly 

 flaked with ireegular snowy spots and lines, colu-

This species, which is not uncommon, difi'crs constantly 

 from V. nivosa, in being of a shorter and broader growth, 

 coronated with sharp spinose scales. It is also charac- 

 terized by a more confused style of painting, of a peculiar 

 sea-green tint of colom-ing. The open white flakes of 

 F. iiivosa are here represented by small broken opake 

 white lines. The shell is very similar in other respects, 

 but in all the specimens I have seen, the peculiarities above 

 noted are well marked, and apparently of specific ira- 

 ])ortance.

 The peppered Volute. Shell oblong-ovate, thick, spire 

 rather short, somewhat obsoletely noduled at the apex, 

 whorls smooth, concavely slanting round the upper 

 part, obsoletely tubercled at the angle, columella 

 four-plaited ; light fleshy-ash, very closely peppered 

 thi-oughout with minute orange-brown dots, longitu- 

 dinally lightning-marked with rather distant olive- 

 black waved streaks, the colour being partially ob- 

 scured with thi-ee bands of greenish-white, columella, 

 base, and interior of the aperture bright orange-car- 

 neliou.

The painting of this beautiful species in all its detail, is 

 of too minute a character to be rendered in a figure. 

 The entire surface of the shell is peppered, so to speak, 

 with small orange-brown dots, and over this are a number 

 of rather distant jagged olive-black streaks running in 

 zigzag style from the sutures to the base. This being 

 the design of the painting throughout, about one-half 

 of it is partially obscured at intervals by three bands of 

 greenish-white film, the pattern being seen thi-ough it. 



The species is at present unique in the collection of 

 Thomas Norris, Esq., to whom I am indebted for this 

 opportuuity of figuriug it of the natural size.
