[Cnidaria] recommended hydromedusae keys for the eastern tropical Pacific

[Andrew Remsen]

I'll be participating in an extensive eastern tropical Pacific cruise 
next month and will be imaging in-situ hydromedusae and other cnidarians 
in the 0.5mm to 5 cm size range and was wondering if anyone has 
recommendations on the best keys to use for identifying them?
Thanks
