In the present catalogue are listed 68 species of hermit-crabs so 

 far known from Japan. They are referable to 1 5 genera. Of the 

 above number of species, four seem to me to be new to science and 

 are here described for the first time, viz., Parapagnrus ijimai, Pagurus 

 watasei, Eiipagnrus gotoi, and Diogenes nitidimanus. Of the genera 

 given in this paper, Parapagurns is taken in the broad sense of 

 including Sympagurus Smith under it. 



In my studies of the group I have had at disposal the entire 

 collection in the Zoological Institute of the Science College, Tokyo 

 Imp. Univ. For the facilities and useful advices given me in that 

 Institute, it is my pleasant duty herewith to return my cordial thanks 

 to Professors Ijima, Watasé and Goto. My thanks are also due to 

 several other gentlemen who have assisted me in obtaining materials 

 from different parts of the country. I am under special obligation to 

 Professor S. Ikeda of the High School of Kagoshima, by whose inter- 

 mediation I have been able to examine not only the collection of 

 that school but also the specimens belonging to some other public 

 institutions of that city.
