CYPRiEA 



environs of Paris^ at Laugnaji, near Bordeaux, and in 

 Normandy; also in Italy and Piedmont: we have seen 

 specimens of a very fine fossil species, nearly resembling 

 C. Mus, but much larger from the Netherlands: they 

 seem to be confined to the newer formations. 



In order to illustrate this Genus, we have been 

 obliged to give two plates, in which are contained the 

 following species : 



Fig. 1. Cypreed Mauritiaria In its juvenile state, before the outer lip is formed. 



2. The same species in its intermediate stage. 



3. A beautiful variety of C. Mappa in its adult state. 



4. C cylindrica. This, besides being the most elongated species we know, 

 has also another peculiarity, that is, the last volution so m<ich exceeds the rest 

 as to form an umbilicus above the point of the spire. 



5. Two views of C. pusttdata. 



6. Two views of C. madagascariensis. 



7. Cypreea elegans^ a fossil from Nehou. 



8. C. Gervillii, Nob. so named because it was discovered by our excellent 

 correspondent M. De Ger^'ille on his own Birth Day, and therefore eminently 

 belongs to him, it is a beautiful fossil found at Nehou ; the following are its 

 specific characters : 



C. Testa oblonga, lineis trans versis plurimis confcrtis, elevatis, acutis^ ia- 

 tegerrimis, in partem auticam duplicatis.
