H. testa ovata,subventricosa,tenui griseola ; costis angustissimis distan- 

 tibus ; interstitiis albidis, roseo rnaculatis, lineis rubro-nigris, confusiuscule 

 undulatis ; columella carnea et violacea. 



Shell ovate, ventricose, rather thin ; spire conical, slightly 

 muricated ; the four whirls which are near the edge are the 

 widest. The ribs are flat, oftentimes narrow, almost all mark- 

 ed at their base by four or five conical denticulations, and at 

 the upper extremity of the last whirl, by four small mucronat- 

 ed tubercles, which appear again upon the whirls of the spire. 

 The coloring of the ribs is of a light gray ; they are circled by 

 rose-colored or white bands in bars ; at their external edge, 

 which is slightly projecting, is drawn a brown or blackish lon- 

 gitudinal stroke, interrupted by small horizontal white rays. 

 The interstices of the ribs are of a grayish pearl color, waved 

 with fine strokes in double bars, which are laced with strokes 

 of a red brown. Rose-colored spots are likewise seen between 

 the ribs. Aperture ovate, of a pale yellow, with several bands 

 of a dark violet. The right lip is ornamented by the last rib, 

 which is undulated throughout its whole length. The colu- 

 mella is polished, arcuated towards the base, and has two or 

 three spots of a bluish violet.

 a new species, under the name of HARPA Rivoliana (Zoological 

 Illustrations, pi. 36), a specimen, which we consider a very old
