Xenophon (3.5.1) states that Tithraustes, not Pharnabazus, sent Timocrates, but the Hellenica Oxyrhynchia states that Pharnabazus sent him. For chronological reasons, this account is to be preferred. See Fine, The Ancient Greeks, 548
Xenophon, at 3.5.2, claims that no money was accepted in Athens; the Hellenica Oxyrhynchia says otherwise. George Cawkwell, in his notes to Rex Warner's translation of Xenophon, speculates that Xenophon may be denying that money was accepted at Athens because of his sympathy for Thrasybulus (p. 174).
