Marginella tricincta. Mar. testd obeso-ovatd, cinereo-carules- 

 cente,fusco trifasciatd , labro incrassato, luteo, intiis Icevi ; colu-

Marginella blanda. Mar. testd ovatd, tenui, sardonychid, obso- 

 lete fasciatd; spird vix occultd, pallidd ; labro subincrassato et 

 subrejlexo, intus lavi ; columella albidd, sexplicatd, plicis superi-

Hab. Cape Blanco, west coast of Africa ; in twelve to fifteen 

 fathoms. 



Marginella imbricata. Mar. testd ovatd, albidd, maculis rufis 

 quadratis prope medium unifasciatd, aliter punctis transversis or-

In one specimen the tessellated band which encircles the body- 

 whorl is broken up into a number of small spots and punctations, so 

 that though these markings present usually a nearly square shape, 

 they are most probably disposed to vary. The shell in some respects 

 approaches M. interrupta. 



Marginella muralis. Mar. testd elongate ovatd, fere subcylin- 

 draced, lacted, nitidd ; maculis pallide rufis quadratis transversis 

 ornatd, interdum albo marginatis, majoribus per series ires dispo- 

 sitis ; labro vix incrassato, subinflexo, intiis sulcata; columelld 

 plicis tribus inferioribus distinctis, obliquis, alteris superioribus 

 obsoletis transversis. Axis 5^ lin.

This is a remarkably pretty glittering species, and the specific 

 name seems justified by the appearance of the pale red regularly- 

 disposed square markings, which resemble the extremities of the 

 bricks in a wall. The labrum is not merely toothed within, but di- 

 stinctly sulcate. It approaches M. Kiener's M. maculosa, but the 

 ornation is quite of a different character, and it has no angular ele- 

 vation on the body- whorl. 



Marginella sagittata. Mar. testd retuso-ovatd, pallidd, lineis 

 rufis sagittatis transversis, alteris longitudinalibus confiuentibus, 

 ornatd; apice puncticulato ; labro subinfiexo , inttis Icevi ; columelld 

 vix quadriplicatd. Axis 5 lin.

Shell shortened, ovate, the ornation consisting of reddish brown, 

 transverse, arrow-headed markings, disposed in regular series and 

 connected by waved longitudinal lines. The labrum is not the least
