This index has been initially prepared from a list of the US stories reprinted. The total page count is too high and it is likely that one or more stories were edited for this reprint. It was common for Federal to merge continued stories by removing the title page of the later parts, or by reducing and combining artwork on some pages.
The cover has been hand-recoloured (note the pen marks) for this Australian edition based on the same colour scheme as the original US printing.
Story ties in with previous story in the original House of Mystery issue, "The Rings of Kur-Alet".
