Callistan n. 1	1933 E. H. Hinton Monsters of Callisto in Wonder Stories Oct. 229/2 Our hosts had put all their blankets and tarpaulins at the service of the men, and had joined the weary circle at the fire’s edge, after turning over the rocket runabout to Diane for her private castle. On the morrow, she and Boaz and the three Callistans would start for Nunei, and there arrange for a transport ship to come back for the rest of us.
Callistan adj.	1933 E. H. Hinton Monsters of Callisto in Wonder Stories Oct. 199/1 For some little time the attraction of the little planet had made us independent of our gravity lines. As soon as we should enter the Callistan heaviside layer, the retractible helicopter screws would be broken out to oppose the gravitational pull, so that under the single influence of magnetic attraction we should drift downward in a bee line to our berth in Nunei. And it was in that moment of my premature self-congratulation that I had the first inkling of disaster.
