 or more cross arms united at tlie ends and tlms pi'esentiiii,' a 

 more or less roin})lete diskdike sliape (r/. r). Knd-platos are 

 well developed in pedicels; tliey are small in |>apil]ae. Nu- 

 merous C-shaped l)odies (_/', g) are found in the layei- below tliat 

 of the tables (0.08 mm. in larj^est diam.). They are also jiresent 

 in an immense numltei' in the cloacal wall, and to some extent 

 in the tentacular wall. The bent, toothed or smooth sujiporting 

 rods (/() are found in large numliers in tlie wall of both jiedieels 

 and papillae (0.48 mm. long.). 



It seemed to me very remarkable that the present species 

 which has hitherto been found exclusively on the Atlantic coasts 

 of Europe and Africa, should ])e found here in Japan. I there- 

 fore made a very thorough and careful examination to see if 

 the Japanese specimens did not present some features difTerent 

 from B. iirai'di. But 1 could not find a single point which would 

 justify me in putting them in another species or in establishing 

 a new species for them. At the same time, I should like to call 

 attention to the remarkalile similarity which a species descril)cd 

 recently by Sluiter {Bnllvjplotes ruhicimchis) presents to my speci- 

 mens as well as to tlie description of S. tiznrcU. >Should that 

 Sluitee's species turn out to be identical witli the one under 

 ti'catmeut, an intermediate station is established for the species, 

 and the occurence of it in Ja])anese waters may not seem so out 

 of place.
