Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Maharaja Pariksit, subduer of enemies, this Revata constructed a kingdom known as Kusasthali in the depths of the ocean. There he lived and ruled such tracts of land as Anarta, etc. He had one hundred very nice sons, of whom the eldest was Kakudmi.
