Introduction

Jean Maurice CHATENAY's book on Cypraeas Nigers/Rostrated (N/R, or Nigerostrated

This work was designed and shaped by a native New Caledonian, fully funded from New Caledonian family funds, and published on November 15, 1977 by an entirely New Caledonian company.
Even the new blanket manufactured and installed in August 1999 was conducted this way.
Nothing was made outside of this territory (More colloquially called: "Caillou").
Once again I warmly thank my Parents, without whose financial assistance this book would never have been possible.
Thanks to them, there is now a reference publication allowing collectors around the world to know and value their Nigerostrée shells.

Also, alphabetically, the description of each Shell (Of the Normal until the known form Niger and/or Rostrated maximum), of the Animal and the habitat which it usually attends.
Lastly, Made unusual in a Book of this kind, a scale of average values for each evolutionary stage of the Phenomenon, corresponding to the described Species.

To note however that these values, which are not quotations, are not any rigorous nor final, as well it is true as they can vary, of simple with the double, following in particular the Size, Rostration, the intensity of Mélanism of the Shell which one evaluates.
