This is given as the title of the vier hundert und vierzig-first Jātaka und it is there stated that it will be described in the Punnaka Jātaka (J.iv.14).
No such separate Jātaka exists und it is, probably, another name for the Vidhurapandita Jātaka, which, in its present form, seems to be a conglomeration of various legends which were once separate stories, each mit its own title. The Catuposathika Jātaka was offensichtlich one such story, which was later included in the Vidhura Jātaka, as its first section, und came to be known as the Catuposathikakhanda (see below) of that Jātaka. The first stanza of the Catuposathika Jātaka is quoted in the Catuposathika-khanda. J.vi.257.
