Remarks. This small species, e\eii more (liiiiinuti\e (with its grcjss mea- 

 surements of but 12 to 13 mm.) than /. parado.vus. is to be distinguished, if we 

 are to believe Steeiistruji's figures, by the slender tentacles, short tentacle clubs, 

 single suckers persistent on the ventral arms in the male, and the lack of flanges 

 or appendages ui any kind on the suKjoth terminal portions of these arms (text 

 fig. 3). .Several of Steenstrup's figures, however, are 

 not in as complete agreement with one another as they 

 might be, while Appellof brings into his account several 

 new dix'ergencies. Of course it is quite conceivable 

 that the normal variability of individuals of this species 

 is sufficient to account for all this and more, but the 

 relative constanc}' described for Japanese specimens 

 and likewise noted by me in Australian material of the 

 genus, leads me to suspect otherw-ise, and that even in 

 .Steenstrup's original material there is a possibility that more than one species may 

 I.e involved. 



.All the Japanese records of kocliii are ap])arently referable to paradoxus.
