In Lycia; and another [island] opposite the city of the Koronitai. Προκόννησος, one of the Sporades in the Propontis; Ἐλαφόνησος, one of the Sporadic islands, having a city of the same name. Ἁλόννησος; Ἀλωπεκόννησος, a city of the Hellespontine Chersonese, founded in accordance with an oracle that commanded that, wherever they should see fox cubs, there they should settle a city. Ἀρκόνησος, an island of Caria. Apollonius in the seventh book of the Carica. Ἀρκτόνησος: thus Cyzicus was called. Ἀρτύμνησος, a city of Lycia, a colony of the Xanthians. Menekrates in the first book of the Lyciaca. Δημόνησος, an island near Chalcedon, from someone named Δημόνησος. Ἱππόνησος, a city of Caria. Hecataeus in Asia. There is also one in Libya, as Artemidorus [says] in the seventh book. Ἑκατόννησος: thus [are called] the twenty islets around Lesbos, as Strabo [says], from Ἕκατον Apollo. For he is honored in different ways in different places: Σμινθεύς, Κιλλαῖος, Γρυνεύς. Κορακόννησος… Alexander in the third book of the Libyca. And further, Πελοπόννησος is among the compounds.
The words in -σσος that are more than disyllabic, having an ι before the end, ending in -σ, being of one gender, are accented on the antepenult: κυπάρισσος—both the plant and the hero and the city. Homer: “οἱ Κυπάρισσον ἔχον Πυθῶνά τε πετρήεσσαν” (Β 519), from Κυπάρισσος the Minyan; but others, as Didymus [says], [derive it] from the multitude of cypresses there, which some also call Κυπαρισσοῦντα and Ἀπολλωνιάδα. νάρκισσος—both the plant and the proper name. Μέλισσος. Μύρμισσος, a city near Lampsacus, as Polemon [says]. Βόλισσος, an Aeolic city on a headland near Chios. Thucydides calls it Βολίσκον in the eighth book (c. 24); but Androtion writes it with a single σ. And they say that Homer made his sojourns in this little town, as Ephorus [says]. Ἀρχέμισσος, the name of a river. Τριπόλισσος, a Thesprotian people, whom Rhianus also calls Τριπολισσίους in the fifteenth book. Βαρβάλισσος, a fortress of the East, walled all around; Θέμισσος, a city of Caria, which Dadas founded, from Θέμισσος a boy, whom wolves tore to pieces. Μούκισσος, a city of Cappadocia. Μύγισσος, a city of Caria. Hecataeus in the fourth book of Genealogies. Παροπάνισσος, a city and a mountain of India, from which the inhabitants are called Παροπανισσάδαι. But Apollodorus in the second book On the Earth says that the mountain was named from them. Some, however, want the mountain to be called Παρπάνισον with antepenultimate accent; but many both accent it on the last syllable and write it with μ, Παρπαμισόν. Strabo, however, writes Παροπαμισόν as a five-syllable word. Ὕδισσος, a city of Caria, from Ὑδίσσος, son of Bellerophon and of Asteria daughter of Ὑδέος, as Apollonius [says] in the fourth book of the Carica. Πεδνήλισσος.
