 nearly to cover the spire.

Marginella t^eniata. Marg. testd ovali, cylindricd, pallide fulvd, 

 fasciis fuscis tribus cinctd ; spird brevi ; aperturd elongatd, postice 

 subangustatd ; columelld plicis quatuor, quarum duo: anticce ma- 

 jor es ; labio externo Icevi, late reflexo. 

 Differing from M . avena in having a shorter spire and the outer 

 lip more broadly reflected. 



In Mr. Cuming's collection. Locality unknown. 

 Marginella albo-cincta. Marg. testd subconicd, subangitlatd, 

 lavi; spird productd; anfractibus angulatis, ultimo fascid albdprope 

 unguium, et alter o ad terminum anticum cincto inter fascias fusco 

 maculato et punctis nigris picto ; columelld quadriplicatd. 

 Provisionally described from a young specimen in Mr. Cuming's 

 collection. When full-grown it would probably resemble M. nube- 

 culata in form. 



Marginella Pseudo-faba. (M. Faba, Lam. Anim. s. vert., vii.) 

 Marg. testd angulatd, antice attenuatd, subrecurvd, pallide fulvd, 

 griseo-nebulatd, punctorum irregularium seriebus 10 sparsim 

 cinctd ; spird prominuld ; anfractibus angulatis, ad angulum valide 

 crenulatis, crassis, paululilm arcuatis, postice angulatis, antice 

 emarginatis, attenuatis. 



Much more angular than the true M. Faba, and has the anterior 

 part of the body- whorl tapering and bent upwards. 



In Mr. Cuming's collection. From the river Gambia, West Africa. 



Marginella Fauna. Marg. testd ovali, subcylindricd, pallidissime 

 earned, spird brevi ; columelld oblique quadriplicatd ; labio prope 

 medium incurvo, extus subincrassato . 



Slightly resembling M. pallida, but more oval; the lower part of 

 the aperture less open, and the outer lip thicker. 



In Mr. Cuming's collection. From the isle of Curasso. 



Marginella multilineata. Marg. testd ovali, stramined, lineis 



rubris numerosis cinctd; spird pene celatd, apice fascid rubrd cir-

in medio tumidd, antice callosd, plicis quatuor ad quinque incequali- 



bus ; labio externo albo, intus crenulato, in medio subangulato, extus 



tenuiter reflexo. 



On the whole resembling tessellatus, but it is much shorter, with 



the outer lip less varicose on the outside, and coloured by numerous 



red lines instead of the square patches. 



In Mr. Cuming's collection. From Belieze, bay of Honduras; 

 Mr. Dyson. 



Marginella varia. Marg. testd elongatd, Icevi, antice expansd,
