Stephanos of Byzantium - Ethnika
Kyllene: a mountain of Arkadia, 9 stades from the foot 80, named after Kyllene, a Naiad nymph. In this mountain, they say, the thrushes become white, but nowhere else at all, and they utter variegated voices; they are hunted by moonlight, but by day, if anyone were to attempt it, they are very difficult indeed to hunt. There is also Kyllene, a harbour of the Eleians. The ethnonym is 'Kylleneus' and 'Kylleniou'; Hermes is also called 'Kyllios', by syncope of 'Kyllenios'.
