(Πόλλις), is first mentioned in B. C. 390 as ἀπιστολεύς, or second in command of the Lacedaemonian fleet ( Xen. Hell. 4.8.11). In B. C. 376 he was appointed navarchus or commander-in-chief of a Lacedaemonian fleet of sixty ships in order to cut off from Athens her supplies of corn. His want of success and defeat by Chabrias are related in the life of the latter [Vol. I. p. 676a.] (Xen. Hell. 5.4. §§ 60, 61; Diod. 15.34; Polyaen. 3.11.17.) In several MSS. of the above-mentioned authors, his name is written Πόλις, but Πόλλις is the preferable form.
