I AET. S. T. IKEDA : THREE NEW AND 



In this place I beg again to express my most sincere thanks 

 to Professor Mitsukuri and Professor Iji:\rA, to whom both I 

 owe much in completing this as well as my former paj^er on 

 Gephyreans. My thanks are also due to my friend, Mr. Miya- 

 JiMA, to whom I am indebted for the gift of the unique specimen 

 on which I had based Thalassema miyajimai. Further I owe 

 a debt of gratitude to Messrs. Yatsu and Tsuchida for much 

 valuable advice and assistance rendered me at Misaki.

The single (female) specimen as yet known of this species 

 was obtained by Mr. Miyajima in 1900 while on a collecting 

 tour in the island of Okinawa, Loochoo Islands. It was found 

 in a hollow in the coral rock along the shore in Tomari, a 

 village two miles distant from the port of Naha. 



On dissecting the female specimen I was fortunate enough 

 to discover in the body-cavity a remarkable worm which I consider 

 to be the parasitic male of the species. 



The Female. 



A colored drawing, in double natural size, of the female in 

 the living state was made on the spot by the collector. It is 

 now reproduced in fig. 1, PI. I., of this paj)er.
