Authors' Notes:
[1] The crew of SCORPION reached Australia after an epic 47-day voyage. After the war one of its passengers, RAAF Sgt Athol Snook met the brother of LtCdr Ohashi and presented a frill-necked lizard to him.

Thanks go to Dr. Higuchi Tatsuhiro of Japan and Jan Visser of the Netherlands.
