determinable sex up to 57 mm. in mantle-length, 

 iii. One specimen, Misaki (Sci. Coll.). Mantle-length 74 mm. ; 



arm-order i, 4, 3, 2. 

 iv A male from unknown locality (Sci. Coll.), in which the 



fourth arm is the longest. 

 All these specimens agree closely with the description by Wülker 

 except in the arm-order and in the horny ring of tentacular suckers 

 having 15-20 short and blunt teeth instead of being quite entire. The 

 teeth are sometimes very indistinct, but can always be easily dis- 

 tinguished from the horny papillae of the papillary area.
