During the last two years I have had several opportunities to 

 collect ctenophores in the neighbourhood of the Misaki Marine Station. 

 The sketches and notes taken on those occasions have formed the basis 

 of this report. To supplement my observations I have also examined 

 the preserved materials in custody of the Zoological Institute, Science 

 College, and of the Tokyo Higher Normal School, all which materials 

 were collected chiefly at Misaki and to some extent at Tateyama in 

 Prov. Awa. In all eleven species have come under my observation. 

 The number includes two Cœloplana species, of which I have prepared 

 a special report to be published in another journal. The present paper 

 deals with the remaining nine species. The descriptions are based 

 exclusively on my own observation of the specimens at my disposal.
