In 1922 Prof. Torsten Gislen recorded and gave notes on tvvo specimens from 

 Dr. Sixten Bock's Expedition to Japan station 12, and in 1927 he recorded and gave 

 notes on two more from Dr. Th. Mortensen's Pacific Expedition station 9. Drs. 

 Bock and Mortensen worked in cooperation in southern Japan, and Bock's station 12 

 and Mortensen's station 9 were in reality the same station, occupied by them jointly.
