Tarzan and the Tarzan Twins

The opening passage of "Tarzan and the Tarzan Twins, with Jad-bal-ja, the Golden Lion" specifies that its events occur immediately after those of "The Tarzan Twins." In relation to other Tarzan stories, the two parts of the Tarzan Twins tale presumably fall between Tarzan and the Ant Men and Tarzan, Lord of the Jungle chronologically, as the initial part was published between these two novels.
