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 Scoétii, at 
the base of the spire. 
Length, 290 inches; altitude, 1,2°; breadth, 155°.

The only specimen I have seen of this peculiar shell is in the Bri- 
tish Museum, and may not be an adult. 
3. Cypr#a Bicotor (Two-coloured Cowrie). Cyp. testd pyriformi, 
colore floris lactis ; fasciis latis, interruptis, brunneis, centrali 
latiori ; basi latiusculd, rotundata ; aperturd subspirali, latiusculd ; 
dentibus numerosis, prominentiusculis, columellaribus crassis, supra 
sulcum columellarem extensis ; margine externo crasso, punctato, 
punctis brunneis discretis ; extremitatibus brevibus, obtusis ; canali 
antico pallidé rufescente-flavo. 
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 cclu- 
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.
