In tlie last of these contributions thirty genera of Ruhiacese were 

 described. In the present one descriptious are given of the twenty- 

 three remaining genera. Our account of the species of Psychotria ought 

 to have been included here. But, owing to an unfortunate circumstance, 

 it has been necessary to keep it back for publication in the next paper 

 of the series. In the accompanying key to the genera, PsycJwtria ia 

 however included. The species described in the present paper number 

 123, and of these 47 are believed to be new.
