The number of species here enumerated is the same as that of DeCandoUe's ' Prodro- 

 mus,' one of DeCandoUe's species {Fh. Foivrecmum, DeCand.) having been suppressed, 

 and a new one {Fh. Fernencmum, Seem.) added. Fh. Thouarsiauum, DeCand. will pro- 

 bably have to be excluded from this genus, its habit being entirely different from that of 

 the genuine Phyllarthrons.
