tending without interruption half of the distance from the angle 

 of the aperture to the base, and concealing the upper part of the 

 perforation; the callus is then reduced to half its width by a rect- 

 angular truncation. Altitude 36, width 28 mm. 



It is with the greatest pleasure that Iname this shell in honor 

 of Monsieur Stanislans-Meunier of Paris, as a token of highest 

 esteem and friendship, and a souvenir of his charming expeditions 

 geologiques.

Shell greatly flattened, smooth except for fine arcuate 

 growth-lines which are strongest on the under surface; whorls five, 

 the first two minute, conical, subsequent volutions flattened 

 above, concavely excavated beneath; umbilicus partly overhung 

 by a tongue-like callus capping the pillar-like umbilical callus 

 which enters and stops up the perforation; aperture large; outer 

 ip slightly sinuous beneath the periphery; the under surface and 

 interior of some specimens show traces of an original chestnut 

 color. Diameter of largest shell 36, altitude 12 mm. 



The nearest ally of this fine shell is Humboldt's larger 

 species, N. glauca, living from Acapulco to Panama.
