short channel running upwards ; spire very prominent ; margins flat 

 and thin, extending much outwards ; the angle formed by the attach- 

 ment of the outer margin to the shell is of a light brown colour, from 

 which anteriorly radiate lines of the same colour over the upper 

 surface of the margin. 



Differs from Cyp. Scottii in its short and gibbous form, in the re- 

 markable flat and broad cream-coloured base, in the very extended, 

 flat and thin margins : the posterior channel has much the form of 

 that of Scottii, but terminates at the apex, and not, as in Scottii, at 

 the base of the spire.

The only specimen I have seen of this peculiar shell is in the Bri- 

 tish Museum, and may not be an adult.

 Shell pyriform, when young more ovate, smooth and shining; of 

 a light cream- colour, having three broad, irregularly interrupted 

 bands of a brown or fawn colour, extending entirely across the shell, 

 the middle one being the broadest, the posterior the next so ; base 

 broad, rather convex, pale cream- colour ; aperture subspiral, rather 

 wide; teeth numerous, rather prominent, on the lip about thirty 

 curving round its edge, and extending about one- third over the lip ; 

 on the columellar side teeth about seventeen, extending from the 

 edge of the aperture over the columellar groove to end on its inner 

 ridge, diminishing on that ridge in prominence towards the posterior 

 extremity, where the denticulation is scarcely observable ; the colu- 

 mellar groove of equal width the whole length; margin, external 

 very thick and prominent (not crenulated), somewhat angular at its 

 outer edge, along which are many small brown distinct spots ; simi- 

 larly coloured spots, but a little larger, are also on the columellar 

 side, where a slight margin exists, and which becomes prominent only 

 to form the anterior extremity ; extremities short, obtuse ; the anterior 

 channel has a very faint orange tinge.

Differs from the Cyp. piperita of Gray in not being cylindrical, but 

 of a pyriform shape ; in being very gibbous, and a much heavier and 

 thicker shell ; in having only three bands, which are very broad and 

 conspicuous ; Cyp. piperita having four, which are generally narrow 

 and obscurely visible in the adult shell, and on the later-formed part 

 of the shell uninterrupted.
