I AM happy to record Mr. Dillvvyn as the first systematic 

 writer who separated this from Mar. persicida, which has 

 reddish spots, and is quite a distinct species. The present 

 is a pretty, though common shell, and observed by Adanson 

 in great plenty on the African coast. 



MARGINELLA prunum, 

 Grey Date Sliell — middle Jigures. 



M. tcAtd ovatd, grised, immacidatd ; spird parvd, conicd ; aperturd 



fused ; columella 4 plicatd. 

 Shell oval, grey, imuiaculate; spire small, conic ; aperture brown ; 



pillar 4 plaited.

The plaits are very strong, and, together with the outer lip, 

 white ; equally common, and from the same country, as the 

 last. " 



MARGINELLA faba.

The whorls of this pretty shell are plaited into little nodules ; 

 it is usually very small. The supposed variety figured by 

 Martini, and mentioned by Mr. Dillwyn, I am inclined to 

 believe, may be a distinct species.
