Remarkable on account of the finely cancellated surface, the nodose 

 angle of the whorls and the style of colouration. The ground colour is very 

 light red, varied with dark brown or red dots or short lines upon the nodose 

 angle of the whorls, and upon the three lower transverse ridges upon the 

 body-whorl. Of these, that nearest the angle is also slightly nodose. The 

 protoconch, consisting of about two whorls, is large, smooth and yellowish. 

 The labrum is thin and very finely crenulated within the margin. 



Quite distinct from P. rapenxU, Petit. The fine cancellation is quite 

 different from the sculpture of that species.

This species is I believe the N. coccinea of A. Adams MSS. as under- 

 stood by Mr. Sowerby (Marine Shells S. Africa, p. 12). As, however, I have 

 never seen a scarlet specimen, and its colouration is so variable, I venture 

 to propose the name poeeilostieta for this apparently quite common shell. The 

 manuscript name coecinea may therefore be disregarded in future. Mr. 

 Sowerby in the Appendix to the above work (p. 5), has suggested that this 

 species is the same as N. coceinella, Lamarck. This, however can scarcely 

 be correct, as that species by general consent is regarded as synonymous with 

 the common N. inerassata of British and European coasts. 



Some specimens of the present species are uniformly orange, excepting 

 the lip which is white within. Sometimes this variety has a white line round
