This species varies considerably in size, and in the bands being 

 darker and paler, and in their sometimes being edged with yellow. 



38. Cyprmainterrupta. — The Broken-banded Cowry. 



Testa oblongo-ovata, subumbilicata, albido-casrulescente, inter- 

 rupte trifasciata, punctisque fulvis nebulata ; basi lateribusque 

 albis; subtus convexa, aequaliter subsulcata. 



2. decorticata. Testa albido-violacea, interrupts trifasciata ; 

 fasciis antice bifidis.

Shell oblong-ovate, blueish-white, clouded with minute yellowish 

 dots, and with three broken brownish bands, the two foremost of 

 which are generally divided spirally into two, and the hinder one 

 mostly single and formed of oblong transverse spots ; the spire is 

 slightly concave, covered ; the base and sides white ; the edge 

 slightly thickened all round, rounded on the sides, and slightly 

 produced at the posterior extremity ; the anterior extremity orna- 

 mented with a brown lunate spot on its upper part ; teeth smallish, 

 even, slightly extended over the lips, so as to make the base 

 evenly grooved. 



This shell agrees in some measure with the description oiCyprcea 

 tabescens of Solander's MSS. {Martini], t. 28. f. 294, 295.) ; but 

 the teeth are small and closer, and the bands are differently 

 placed, as the hind one is only a little distance from the spire. 

 I therefore consider it a distinct species, which is always to be 

 known by its evenly sulcated base and articulated bands. 



39. Cypraa quadrimaculata. — The Four-spot Cowry. 



Testa oblongo-ovata, albido-caerulescente; dorso punctis minu- 

 tis, fulvis, nebulato ; basi marginibusque albidis ; extremitatibus 

 nigro bimaculatis ; subtus planulata insequaliter semisculata.

Shell oblong-ovate, blueish-white, with the back speckled with 

 minute fulvous dots ; the spire flat ; the base and margin white ; 

 the edge slightly thickened, rounded at the sides; the extremi- 

 ties rather produced, with two blackish-brown spots on the upper 

 part of each; the base flattish; aperture rather narrow; teeth
