Delessert's Volute. Shell fusiformly oblong, slightly 

 recurved at the base, spii-e acuminated, apex sharp, 

 whorls longitudinally lyi-ately ribbed, ribs numerous, 

 narrow, rather sharp, somewhat flexuous, interstices 

 striated, transversely obsoletely marked with faint 

 pricked grooves, columella slightly arched, thj'ee- 

 plaited at the base, with numerous fine thread-like 

 plaits above, aperture oblong-ovate, lip thickened, 

 vai'icose, sharp at the edge ; flesh-coloured, profusely 

 stained with orange-red, transversely marked with 

 red and chestnut hues, interior of the aperture white.

Hab. Tiger Bay, Madagascm\ 



Distinguished from the V. mitraformis, to which it is 



the nearest allied species, by its more acuminated growth, 



narrower and more numerous vilis, and bright orange-red 



colour.

The spindle-shaped Volute. Shell somewhat elon- 

 gately fusiform, contracted and rather largely emar- 

 ginated at the base, spire acimiinated, papillary at 

 the apex, whorls slanting round the upper part, 

 then a little swollen, smooth, minutely decussately 

 striated beneath the lens, columeUa three-four-plaitcd, 



plaits very oblique, inconspicuous, aperture rather 

 narrow, lip rather thin, but little reflected ; brownish 

 white, loosely reticulated with light chestnut trian- 

 gularly configiu'ed lines, columeUa and interior of the 

 aperture orange-carnelion.

Hah. Australia. 



It has been remarked that this beautiful species is 

 scarcely distinguishable from V. papillaris, but a compa- 

 rison of the figm'cs of each in this monograph, wiU show 

 that, independent of form, they are characterized by a 

 very diflerent design of painting. The apex is much less 

 papiUary in the species under consideration, and the shell 

 is uniformly larger, and of a more attenuated growth. 

 The pattern consists merely of a loose irregidar net-work 

 of light chestnut, not disposed in bands of clouded 

 blotches, nor exhibiting any sharply-defined triangular 

 light spots.

 The jiitre-shaped Volute. Shell fusiformly ovate, 

 spire rather acuminated, whorls longitudinally lyrately 

 ribbed, ribs obtuse, rather flatly convex, interstices 

 striated, columeUa three-plaited at the base, with 

 numerous fine thread-Uke plaits above, aperture 

 oblong-ovate, lip thickened, varicose ; whitish, 

 painted with, blotches of pui-plish chestnut, interstices 

 marked transversely with fine brown lines, aperture 

 whitish.

Voluta multicosiata, Broderip. 

 Hab. AustraUa. 



This species is less sharply acuminated than the V. De- 

 lessertiana, and the ribs are broader and about one-fourth 

 less in number. The painting is very diff'erent, both in 

 colour and design.
