On the Foraminifera of Barhadoes. {Etude sur les Foraminifhres de la 

 Barbade, Sec) By M. Erioist Vai^dex Broeck, &c. 8vo. 98 pages, 

 with 2 plates. Brussels, 1876. (From the ' Annales de la Soc. 

 Beige de Microscopic.') 



This memoir on some recent Foraminifera collected by the late 

 L. Agassiz at about 100 fathoms depth, near Barbadoes, in the 

 West Indies, is of considerable interest on account of the careful 

 treatment of the Microzoa under notice, the elegant and trustworthy 

 illustrations, and the enlightened views of Foraminiferal classification 

 and nomenclature which the author clearly and earnestly advances. 

 The series of forms is not numerous, but very interesting as 

 varieties and subvarieties of well-known t3'pes ; and these serve as 

 a groundwork for a thoughtful exposition of the principles of clas- 

 sification adopted by Von Reuss in Germany and by Carpenter and 

 others in England. The Foraminifera described and figured are : —
