no. 2073. HOLOTHURIANS FROM NORTHWEST PACIFIC— OHSHIMA. 255 



with larger holes, measuring 220-280/* in diameter (fig. 17c). No 

 anal teeth and papillse are found. No account concerning tentacles 

 and viscera can be given for want of the anterior part of body. 



The present species very much resembles G. californica Ludwig, 

 but differs from it in having tables besides the spinose plates. I 

 take much pleasure in dedicating this new species to the late Prof. 

 Hubert Ludwig of the University of Bonn.
