The magpie Purpura. Shell ovate, rather thick, some- 

 what venti-icose, whorls angulated at the upper part, 

 encircled beneath mth two rows of rather distant 

 prominent tubercles, interior of the aperture striated 

 with reddish brown, aperture yellowish, tessellated 

 with black at the margine.

The comparison of affinities which M. Kiener draws be- 

 tween this species and the P. armigera, is quite uncalled 

 for, the two species being far removed from each other ; 

 it approaches rather to the P. bitubercularis, but may be 

 distinguished by its broader and more ventricose shape, 

 and by the more solid and obtuse growth of the tubercles, 

 the aperture also difl'ering in being striated.

The double-tubercled Purpura. Shell oblong-ovate, 

 transversely impressly striated, whorls slightly angu- 

 lated at the upper part, encii'cled beneath with two 

 rows of acuminated prickly tubercles, denticulated 



within ; exterior conspicuously variegated with ashy

I consider M. Kiener perfectly correct in his illustration 

 of tliis species, and that his figm-e is in every respect iden- 

 tical with that of Seba.

The intermediate Purpura. Shell oblong-ovate, 

 spire short, a little acuminated, whorls slightly de- 

 pressed at the upper part, transversely impressly 

 striated, encii'cled with rows of obsolete tubercles, 

 apertxire rather large, lip flatly thickened, nodulous 

 within; very black, spaces between the tubercles 

 blotched with white, columella and edge of the lip 

 stained with purple-brown.

Rai. ? 



An interesting well-defined species, quite distinct from 

 either of those between which M. Kiener has considered 

 it intermediate.
