' The botanical collections made during the progress of the biological survey 

 of Panama, conducted by the Smithsonian Institution several years ago, con- 

 tain many specimens of Piperaceae, which, together with other unidentified 

 material, were sent to the late Casimir de CandoUe, the preeminent authority 

 upon this family, for elaboration. Among the Panama specimens are repre- 

 sented 27 new species and four new varieties ; descriptions of these, by 

 Mr. de Candolle, are given herewith, the types being in the U. S. National 

 Herbarium. The results of Mr. de CandoUe's study of the Central American 

 material, chiefly from Guatemala and Costa Rica, will be presented else- 

 where. — Frederick V. Coville.
