Akune, Satsuma Province. One female. Cat. No. 332857

The specimens from station 4946 agree very well with Hoyle's 

 original description, the only discrepancies from this being that 

 the longest arms are not the second pairs but the fourth, and that 

 the fins extend straight to above the spine and do not pass on to 

 the ventral surface of the mantle. The remaining specimens accord 

 with Appellof's description better than that of Hoyle's, especially in 

 the structure of the gladius.

This variety is separated from the typical form by the weaker 

 hectocotylization, by the smaller size of spermatophores, by the more 

 rounded contour of the posterior end of the gladius and by the para- 

 bolic curvature of the posterior rim of the iimer cone. Measurements 

 of type: dorsal length of mantle 34 mm.; breadth of mantle 14 mm.; 

 maximum breadth of fins 2 mm.; length of fu'st arms 13 mm.; of 

 second arms 9 mm.; of tlind arms 8 mm.; of fourth arms 10 mm.; 

 diameter of largest armsucker 0.4 mm.; of largest tentacular sticker 

 0.6 mm.; breadth of gladius 7 mm.
