During the past five yeai's approximately 1,000 new species liave been 

 described from tlie Philippines, the material on which the}'- were based 

 l)eing for most part of recent collection. In spite of the large amount 

 of work accomplishciL the nuui1)er of new Tonus that are con>stantly 

 being found is surpi'ising, and our herl)arium to-day contains several 

 hundred undescribed species, while additional ones are found in nearly 

 every collection that is uiade, especially in those from previously unex- 

 plored regions. 



In the present pa^jcr rc])resentatives ot six genera previously not 

 known from the Archipelago are recorded. Eight species, first described 

 from extra-Philippine material, are also here listed for the first time 

 from the Philippines, and about sixty species are described as new. One 

 new genus, Sagitti petal uni, of the Eliizoplioraceac, is described.
