This is a very complete memoir on Swiss Unionidae. 



The following is described and figured as new: 



Anodonta Pictetiana, Mortillet, (pars). 



Mollusques terrestrea et fluviatiles de la Voyage du Dr Friederich 

 Welwitsch, execute par ordre du Gouvernment Portugais dans les 

 Royaumes d'Angola et de Benguella. By Arthur Morelet. 4to. 100 

 pp.* of text, and nine beautifully colored plates. Paris (Bailliere et Fils), 

 1868. 



Thirty-odd pages of this work are devoted to a physical de- 

 scription etc. of the countries whence come the shells that are 

 afterwards figured and described ; then follow, in an appendix, 

 lists of the species and shells described from Tripoli, Egypt, and 

 the more southern provinces of Africa, very important as a con- 

 tribution to geographical distribution. We are informed that 

 the natives of Dongo use a species of Achatina, strung like our 

 Indian wampum, as their money of commerce. Married females 

 universally wear these strings of shells as ornaments, but to 

 unmarried ones they are forbidden.
