In one specimen the tessellated band wh!ch encircles the body- 

 whorl is broken up iuto 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 guadratis transversis 

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

 sitis; labro vix incrassato, subinfiexo, intiis sulcato ; 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 sųuare markings, which resemble the extremities of the

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

 omation 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 confluentibus, 

 ornatd; apice puncticulato ; labro subinfiexo, intiis leevi ; columelld
