Notes on Japanese Schizopoda. 



By 



K. Nakazawa, Rigakuslii. 

 With Plate VIII. 



In my studies of the Japanese Schizopoda I have been able thus 

 far to collect seventeen species in all. Of that number, five are 

 referable to species already known, viz., Neomysis intermedia Czer- 

 niavsky, Enphaiisia pellucida Dana, Euphaiisia spleudens Dana, Rhoda 

 inermis (Kröyer) and Rhopalophthalmus egregius Hansen ; while the 

 remaining twelve seem to be new to science. It is proposed in this 

 paper to give diagnoses of these new species and, in addition, of 

 RhopalophtJialinus egregius Hansen, since this species has been but 

 imperfectly known. 



I beg here to express my thanks to Prof. Dr. Ijima for the kind 

 encouragement given me during my studies and also to all those 

 gentlemen who helped me in collecting the material.
