aperture narrow, much curved at the posterior third of its length, 

 the other two-thirds nearly straight; teeth white, distinct, even, 

 about twenty-seven ,on the outer side, extending but slightly over 

 the lip ; on the columellar side about twenty-four, broader at the 

 anterior end, while along the continued edge of the aperture to its 

 posterior extremity are mere indications of teeth ; columellar sulcus 

 deep and broad, not extending beyond the more prominent teeth ; 

 base broad and flat, its entire circumference of an uniform dark, 

 reddish-brown colour, or spots of a similar colour, the colour lessen- 

 ing in intensity towards the middle portion of the base, which is 

 white, as is also the interior of the shell ; margins project, especially 

 that of the lip : extremities produced, the posterior forming sharp or 

 thin edges, and extending much upwards ; that on the columellar side 

 terminating at the apex of the spire ; the anterior extremities also 

 thin, and the channel upright. 



I have seen this shell only in the adult state. It has no general 

 characteristic in common with any known species ; the extremities 

 however have much similitude to Cyproea Scottii ; but it is a much 

 shorter, more gibbous, heavier and thicker shell.

antice subacuminatd, postice et mediane valde gibhosd ; colore floris 



lactis, maculis fulvis, panels irregulariter sparsis ; basi valde 



plana et laid ; marginibus externis mediane fulvo-brunneo punctatis, 



punctis discretis ; aperturd laid, subspirali ; columelld postice gib-

late distinctis ; lateris externi cequalibus paululum extensis, antice 



minoribus, circa viginti-novem ; extremitatibus, posticd productd, 



pland, canalem latam sursumformante, anticd minus productd, con- 



vergente, canalem brevem sursumformante ; spird valde conspicud ; 



marginibus planis, tenuibus, valde extensis. 



Shell ovate, anterior end rather pointed, the posterior and middle 



very gibbous ; of a cream-colour, a few fulvous spots are irregularly 



scattered over the entire back and sides of the shell, apparently the 



commencement of the deposition of colouring-matter ; base flat and 



very broad, on the outer edges are discrete fulvous brown spots, the 



rest of the base, the teeth, and the interior of the shell are of a clear 



cream- colour ; aperture wide, spiral ; columella gibbous posteriorly, 



a slight sulcus at the anterior end ; teeth form, on the columellar 



side, a single angular serrated edge, about twenty in number, wide 



apart and not very prominent ; on the other side they are more 



regular and even, extending, slightly prominent, half across the lip ; 



they are smaller and more perfect towards the anterior extremity, 



and about twenty-nine in number ; the extremities are produced, flat, 



form a broad channel, passing upwards at the posterior end of the 



shell, and terminate at the outer side of the apex of the spire ; the 



anterior extremities are much less produced, and converge, forming a
