This specimen is much larger than the type, measuring 63 mm. 

 in mantle length. It deviates from Chun's description in having 

 more numerous tubercles on the hyaline streaks of the mantle, and 

 longer arms, the order of which is 3, 4, 2, 1, instead of 3, 2, 4, 1. 

 Further, the arms and tentacles both have more suckers, and the 

 connective suckers of the tentacles are accompanied with fixing pads 

 not only at the carpal region, but throughout the entire series.
