EXPLANATION OF PLATE L 



Figure 1. Pupa ringens, Nobis. 



P. testa cylindracea, attenuato-subacuta, subfusca, subumbi- 

 licata ; rugis albis longitudinalibus obsoletis crebris ; sufuris 

 crenatis ; apertura quinquedentala ; labro margine albo, reflexo- 



Hab. Brazil. 



This shell has one single and one double tooth on the 

 inner lip, and two single and one triple tootb on the 

 outer, and has a blackish stripe from the umbilicus 

 round under the reflection of the lips to the suture of 

 the body whorl. 



Figure 4.4. Pupa egregia, Nobis. 



P. testa ovato-turgida, reticulata obsoleta, rosea, ventricosa ; 

 plicis obliquis undatis ; anfractibus convexis, apertura alba, 

 columella subtortuosa ; labro repando. 



Hab. Brazil. 



This is also a land shell, and very light for its size ; 

 the margin is elevated round the whole aperture ex- 

 cept at the superior extremity. It has a line of orange 

 surrounding the entire margin, and the plaits on the 

 convexity of the whorls resemble those of the Bucci- 

 num undatum. 



Figure 2. Megaspira Ruschenbergiana, Lea. 



This is a new and interesting land shell from Brazil, 

 for which Mr. Lea considers it necessary to form a 

 new genus. His description of it will appear in the 

 Transactions of the American Philosophical Society 

 of Philadelphia.
