178 K. MTTsrKrra : studies on 



nets in Yodomi in 80 fatliom-;. Strangely onougli, the species is 

 also found in abont the same depth in the Japan Sea in 

 Hakui District, Province of Noto, for the specimens from which 

 locality I am indebted to the goodwill of Mr. Y. Shioi. There 

 the specimens, dried for commerce, are known as " Mukade-iriko." 

 It is therefore reasonable to snppose that the species will be 

 found in intermediate stations. 



This species is near to SHchopus griegi ()stergre\, but I can 

 not detect any X-shaped spicules below the layer of tables. 

 Moreover the calcareous bodies in the cloaca! wall, etc., are much 

 more complex than in that species. 



I have pleasure in naming this after my friend, Mr. A. Owston, 

 wlio has been instrumental in bringing \\\) many treasures from 

 the depths of the Sagami Sea, and to whom T owe some specimens 

 of this species.
