About forty specimens of the above species were collected 

 by me, in April, 1901, in the Kiukiu Islands. The body 

 reaches about 2 cm. in length and 7 mm. in maximum width ; 

 the proboscis is 2-2.5 times as long as the body and much 

 narrower (Fig. 23). The color is deep green on the body and 

 a lighter green on the proboscis ; the anterior ventral portion of 

 the body shows through the body-wall a reddish color caused by 

 the sexual cells in the oviduct. Thus, in the color of the female 

 the species approaches closer to Bonellia pumicea Sluiter (36) 

 than to the Mediterranean specimens of B. minor ; but the 

 anatomy of the female as well as the general structure of the 

 parasitic male, essentially agrees with the description and figures 

 of the latter species given by Rietsch except in the one point 

 that the anal glands in the female Japanese specimens bear short 

 branches, from each of which arise about 5-7 funnels which 

 are relatively longer than in the Mediterranean specimens (see 

 Fig. 101). 



Fig. 102, drawn from a stained preparation, represents a 

 male which was found in the pharynx of a female. The males
