Remarkable for its broad, abbreviated form. In some of its 

 characters it is allied to N. muricata, but its surface has much 

 more numerous and more delicate asperities. Some specimens 

 are distorted and still more finely sculptured, losing in a great 

 degree the longitudinal folds. Bucc. scabrum, Dunker, must be 

 like it, but is described as larger, more solid, and slender. 



Nassa cinctella. T. solida, ovato-conica, nitida, albida 

 linea unica rufa cincta, plicis longitudinalibus acutis ad 10 et 

 striis volventibus ad 8 decussata : spira conica, anfr. 7 planius- 

 culis anguste tabulatis, ultimo subgloboso § long, testae ade- 

 quante : apertura angusta, ovalis, 4 long, testae hand equans ; 

 labro crenulato, extus incrassato, intus 7-sulcato ; columella? callo 

 haud appresso, concinne rugoso; incisura. siphonali angusta, pro- 

 funda. Long. /^ ; lat. £ poll. Hab. Pacific Ocean. 



This very pretty shell is well marked by its short conical 

 form, its few prominent ribs, shouldered whorls, and thread-like 

 vitta. It accords well with Bucc. Jonasii, Dunker, except that 

 one of the principal characters of that shell is to have the interior 

 of the lip smooth. 



Nassa. casta. Testa tenuis, lanceolata, vitrea, alba fasciis 

 rubiginosis binis cincta, longitud. costato-plicata ; plicis ad 14, 

 striis remotis volventibus decussantibus : spira acuto-conica, anfr. 

 8 convexiusculis, apicalibus politis, ultimo § long, testae ade- 

 quante: apertura elliptica ; labro acuto, intus 11-striato ; colu- 

 mella callosa, concinne corrugata ; sinu siphonali amplo. Long.

This elongated, glistening shell has no one with which it may 

 be well compared. It is a little like Bucc. macula in size and 

 form, but in other respects it is more like B. Cuvieri. 



Nassa acinosa. T. solida, ventricosa, ovata, lutescens cine-
