Hab. North Coast of Austraha ; Jukes. 



Closely allied in form to V. Norrisii, it diflers in being 



eucu-cled with four rows of distant chestnut-red spots, of 



which there is no trace in that species.

The much-desired Volute. Shell cylindrically oblong, 

 somewhat Olive-shaped, spire short, conical, obtusely 

 papillary at the ape.x, whorls smooth, slanting round 

 the upper part, then rather swollen, and gi-adually 

 attenuated, coluinella strongly fom'-plaited, aperture 

 rather narrow, lip but Uttle thickened ; pale rose-

SOWERBY, MS. 



Hah. Port Lincoln, South Austrabo. 



This very beautifid new Volute, from the collection of 

 the Rev. W. E. Crotch, remarkably distinct fi-om any 

 species hitherto known, may be regarded as the type of a 

 new section of the genus, partaking of the Cone and Olive 

 foi-m. It is of a delicate orange-roseate hue, crowded 

 throughout with fine sharply zigzag chestnut-red mai'ks, 

 exhibiting two faint bands. The body-whorl is covered 

 with an extremely thin deposit of enamel of a milky hue, 

 by which the painting is only very sKghtly obscured, 

 whOst the columella and interior of the aperture are of a 

 rich orange-red carneUon. Near the lip the painting sud- 

 denly assumes a more exact style of patteni, disposed in 

 triangular reticulations of a darker blueish tint, as if the 

 pencil, so to speak, of the animal had been labouring up 

 to this time in a distm-bed condition. It is the only spe- 

 cimen that has been yet seen.

 Ferussac's Volute. Shell ovate, rather ventricose, 

 somewhat truncated at the base, spii-e short, sutures 

 rude, apex papillary, whorls smooth, or roughened 

 with ridges of growth, rounded at the upper part, 

 columella rather depressed, four-plaited, front plait 

 strong, hind plait nearly obsolete, apertm-e wide open ; 

 dull bay brown.

Hab. ? 



An extremely rare species, described and figured some 

 five and twenty years since by IMr. Donovan, from a 

 polished specimen, which he states to have been treasm-ed 

 for a long whUe previous in a private cabinet. It was 

 supposed to have been received from the Strait of Magal- 

 haens. The specimen here figured is from the collection 

 of the Rev. W. R. Crotch, and there are two or thi-ee in the 

 British Mnseum, of which the locality is equally unknown.
