linns octo vel novem transversis, supra lahruvi et marginem 

 continuis. 



Shell ovate, smooth, the whorls even (not crenulated), of a light 

 yellow-brown colour, having on the last whorl nine rows of distinct 

 small black spots, or short markings, obliquely longitudinally placed, 

 the two posterior rows of which are continuous along the whorls of 

 the spire even to the apex ; spire very prominent, whorls rather gib- 

 bous ; base round ; aperture very wide ; the columella has four white 

 prominent plaits, the two anterior passing obliquely outwards, the 

 first to form the inner elevated side of the channel, the two posterior 

 are transverse ; lip, slightly bowed, is thick aud marginated, and has 

 eight or nine nearly equidistant, dark-reddish, somewhat broad lines 

 crossing its edge and continuing over the margin ; margui continuous, 

 but with much less thickness, over the arch of the channel, aud with 

 the first or anterior plait ; channel broad and deep, obtuse. 



Long, j^ of an inch ; wide, ^^ of an inch.

The only specimen 1 have seen of this pecuhar species is not in fine 

 condition ; when so, it must be very beautiful. It differs from Mar- 

 ginella Faba, Linn., in the evenness of the shoulders of the whorls, 

 its less attenuated form, and the linear markings of the margin, &c. 



Marginella pulcherrima. Marg. testa oviformi,fulvescente, 

 fasciis albis quinque, angustis, transversis, maculis Unearibus 

 nigris, in centros fasciariim conspicuis ; interstitiis fascia primd 

 ad secundam fasciam, tertidque ad quart am, lineis phtrimis 

 tenuissimis fulvescentibus longitudinalibus notatis ; aperturd 

 alba, latiuscula ; columella quinque-plicata ; labia tenui ; apice 

 distincto. 

 Shell oviform, shining, of a light fawn colour, with five transverse, 

 distinct, narrow, even, uninterrupted white bands siirrounding the 

 shell, from the edge of the lip, the two anterior terminating at the 

 columellar edge of the aperture, the others proceeding inwards over 

 the columella ; the posterior is always the least distinct (conspicuous) : 

 floating, as it were, in the centre of these white bands, are very dark- 

 brown or black, equidistant, linear markings or streaks, and similar 

 markings in colour and form radiate obliquely on the slight iddge 

 which encircles the spire : the spaces of the shell between the an- 

 terior band and the second, and between the third and the fourth, 

 are occupied by numerous, fine, longitudinal and parallel light-brown 

 lines, the other spaces between the bands are irregularly marked with 

 the same colouring, varying in individual specimens, in intensity of 

 coloration, especially in the middle space (that between the third and 

 the fourth bands) ; base round ; aperture white, rather wide, flexuous 

 posteriorly ; five plaits on the columella ; the three anterior project ; 

 the first is continuous with the inner side of the channel, the second 

 takes a similar direction behind it, passing obliquely over the base of 

 the shell, and next this is a white varix following outside the aperture 

 a similar direction, on which are four or five dark-brown spots ; lip 

 thin, no margin ; apex perceptible.
